The printing cylinder 150 has a shaft 210 on 30. During this process, the passport softener causes a further scanning device 200 to be marked on the paper web 30, the derivation of which is brought the passport pulse through the photocell 115 for each printing cylinder revolution. This pulse generates the monitoring zone signal and the cylinder - is emitted on the line 303 to the amplifier 350 pulse. This device 200 has, as from and from this via the line 305 to the passport-Fig. 3, a pair of photocells CR 1 and 35 pulse formers 450 transmit. This shaper 450 CR 2 as well as masks 284 and 266 (cf. also FIG. 2 b shapes the pulse in a manner similar to that of the shaper and 2 c). The masks 284 and 266 rotate at 430 to give a similar needle pulse over the Leider shaft 210 and cylinder 150. During a range 451 of the cylinder rotation to be determined on the pass pulse gate circuit 460, light falls. The pass pulse D is shown in FIG. 6 from the light source 270 to the photocells CR 1 and 40. The output CR2 via line 461. Since the position of the cells CR 1 and Ci? 2 output signal is known to the pass pulse storage unit 520 during their exposure, the signals transmitted by in order to end the further charging of the condensate cells are available in a specific gate C 53. The impulse is also about relationship to one another. The cell CR 1 generates the line 462 given to the gate circuit 470, monitoring zone signal whose rising edge 45 rises linearly around the arrival of the pass pulse and whose edge steepness shows proportionally.

nal the speed of the printing cylinder 150. The photocell CR 2 emits a gate C47 and C 53 via a line 302, starting from their original needle-shaped impulse at a certain point in the manure, through the monitoring zone cylinder rotation. The monitoring zone signal carried by both capacitors is controlled via the line 301 and is fed to the monitoring zone signal amplifier 410 at any point on this signal. While the same voltage is charged: The speed of the rend of the rising edge of the monitoring pressure cylinder is decisive for the steepness of the zone signal, the needle-shaped cylinder pulse is the rising edge of the monitoring zone signal. The output and given over the line 302 to the cylinder 55 equal amplitudes of different monitoring pulse shaper 430. zone signals therefore give the

When the impulses from the cylinder and the paper storage unit 510 and the passport pulse storage unit 60 are in the correct relationship to one another, 520 transferred. The two storage units are the same if they hit the monitoring zone signal built up, and each of these is through the same point.

of these capacitors, then it is proportional to the displacement between cylinder and paper web. The direction of this shift depends on which of the capacitors has the larger charge has.

The amplifier 530 amplifies the control signal dependent on the error in order to excite the solenoids 535 and 536 shown in FIG. 5 depending on the direction of the displacement. The solenoids 535 and 536 in turn control the direction of the flow of the operating fluid from the control device 80 through the pipes 73 and 75 to the servomotor 70 in order to move the piston 71 and the compensating roller 50 in a known manner and thus adjust the position of the paper web 30 accordingly . The amount of movement is proportional to the amplitude of the actuating signal. Since the differential amplifier 530 is only responsive to a difference in the charge of the two capacitors C 47 and C 53 , and since such a difference can only occur after either only the pass pulse or the cylinder pulse has been received, the amplifier 530 operates to accept the The position of the roller 50 and the paper web 30 are adjusted until the appropriate pulse is received in order to also terminate the charging of the other capacitor C 47 or C 53. When the subsequent monitoring zone signal is received, the charge on capacitors C 47 and C 53 is adjusted to the same value. The amplifier 530 returns to its original state. If no control signal is derived, this naturally indicates that the paper web and cylinder are aligned with one another.

The scanning device 200 , which supplies the monitoring zone signal and the cylinder pulse, is described in more detail below. The general characteristics of the device can be seen from Fig. 1, the various details of the construction from Figs. 2, 2a, 2b and 2c, certain mechanical details of the construction being omitted because they would unnecessarily prolong the description.

As shown in FIG. 1, the device 200 is attached in the same axis with the printing cylinder shaft 210. It has an end plate 230 with a number of openings made therein. One of the latter has a window 222 through which the pointer 224 can be seen. The pointer 224 is also mounted in the same axis with the shaft 210 and rotates with the same. The observer now sees the position of the pointer 224 through the window 222 and can then align the position of the photocell masks with the pointer 224 by means of the knurled knob or handwheel 220 , as will be explained below.

Directly above the knob 220 is a window 290 with a vertical marking line 292, through which a dial 280 provided with a graduation can be seen in order to be able to determine the respective setting of the masks for the pointer 224 and thus also for the pointer Pressure cylinder and its shaft 210. A knob 234 is attached above the window 290 to regulate the position of an electric motor 236 within the device 200, as can be seen from FIG. This motor 236 can rotate the photocell masks to any position. Furthermore, a switch box 241 is attached to the device 200 , through which various electrical connections to the motor 236, the lamp 270, the photocells CR 1 and CR 2 and a transistor Tl are passed.

The arrangement of the various components within the device 200 is shown in FIG. 2 shown. The device is surrounded by a cup-shaped housing 250, in cross section in the shape of a U, on which the end plate 230 is attached. The impression cylinder shaft 210 or an extension thereof goes into the housing 250 , which is held on the shaft by means of the hub 252 and the bearings 254 .

At its end, the shaft 210 has a recessed part in which an expansion plug 212 with a conical part made of soft metal is inserted and tightened by means of a screw bolt 214 in order to connect the shaft 210 and the hub 252 rotatably to one another. The screw bolt 214 is thus screwed into the end of the shaft 210 to bring about the necessary interaction between the shaft 210 and the hub 252 , while the nut 216 is provided to push the plug 212 out of the recess when the hub 252 is removed from the Wave 210 wants to solve.

The pointer 224 is attached to the left side of the hub 252 and rotates with the same. The position of the pointer can be determined through the glass window 222 , which in turn is attached to the gear wheel 282 together with the knob 220.

The hub 252 carries a pair of spaced apart vertical disc-shaped masks with the walls 284 and 266 as well as three spaced bearings 254. The wall 284 can consist of one piece with the hub 252 , while the wall 266 on the hub 252 by means of the screws 253 is attached. This arrangement was chosen primarily to facilitate the assembly of the various components. One of the bearings 254 carries the gear 282, another carries the rear side plate 258. The third bearing is located in the hub part of the housing 250. The shaft 210 thus rotates together with the hub 252 and the masks 284 and 266 as a unit the impression cylinder, while gear 282, plate 258 and housing 250 remain stationary during normal operation. Gear 282 can be rotated independently of the other parts by knob 220 or motor 236 , and because gear 282 is connected to side plate 258 by bolts that are inserted into spacers 249 that are out of radial dimension of masks 284 and 266 , side plate 258 is rotated concurrently with gear 282.

On the inner vertical wall of the housing 250 sits a slip ring carrier 278 in the form of an insulating block with several electrically conductive slip rings 276 separated from one another for the expansion of electrical circuits from the switch box 241 to various electrical components of the device 200 via brushes attached to the plate 258.

A front view of a portion of the side plate 258 is shown in Figure 2a. This plate is provided with a series of spaced holes 257 , each of which is a different radial distance from the center of the plate

258 has. Each of these perforations takes in a known manner. As can be seen, the opening 286 comprises a brush to a part of the common circular part 287, which is connected to the associated slip ring 276 to the front and to the rear in slots 288 , which close in parallel. In addition, a perforation 257 takes place on the circumference of the wall 284 . This photocell CR 2 for the cylinder reference signal on, in 5 slots extend in an arc of a certain radial distance from the center about 18.5 ° on both sides of a radius from the point of the shaft 210th axis of the shaft 210 to the center of opening 286.

A hole 256 takes the transistor Tl , the diameter of the circular part 287 is while through the holes 259 the bolts with substantially the same as the diameter of the spacers 249 to be exposed on it between 10 border front of the photocell CR 1, so that when the Side plate 258 and gear 282 through- the center of opening 287 to the center of which are inserted. The perforations 259 are aligned, photocell CR1 is aligned, the practically the same maximum perforations in the gear 282, so that male exposure is achieved. In this aligned the center of the photocell Ci? 2 is aligned with the th position, you get the maximum amplitude in the middle of the photocell _{15 of} the monitoring zone signal, which is located in the gear wheel 282 , whereupon the same as CR 1 for the monitoring zone. The version for the waning. The desired part of the monitoring the photocell CR 2 in the perforation 257 is so zone signals, however, from the beginning of the same create that only a very narrow slot of approximately only an arc of approximately 10 °, 0.1016 to 0.1524 mm width of the light coming from the lamp and during this part the pulses of 270 light will pass through. The perforation 255 produced 20 cylinders and paper web. The linear offer for connection to a channel 248, in the rise of the surveillance zone signal, must therefore be which wires connecting the electrical lines are at some distance from the coincidence of the connections to the lamp 270 and to the one in the center of the opening 287 with the center of the Photocell gear 282 seated photocell Ci? 1 extend. CR 1 take place. So if the position of the photocell CR1

The lamp 270 supplies the light for the excitation 25 through the circular arc in the form of the dashed line of the photocells CR 1 and CR 2 and is located between 291 is intended, then the exposure area increases see the two masks or walls 284 and for the photocell CR 1 in an essentially 266. Since the light should only excite the photocells in a linear ratio of about 10 degrees of arc, if suitable openings to be described below are indicated by the dash-dotted radius 283 . The extent to which the walls 284 and 266 of the exposed area increase to a maximum of the photocells CR 2 and Ci? 1 are aligned, value when the center of the circle, which is part of the lamp is preferably so that it is defined by the dashed line 291 , in by means of the bearing block 272 at one or more of the radius 293, which passes through the center which passes through the spacers 249 or the opening 286 on the channel 248 , falls. The angular distance is suspended while the electrical connections of FIG. 35 are placed between the line 283 and the radius 293 of the wires in the channel or tube 248 at the midpoint of the opening 287 to the axis of FIG. The lamp 270 is, therefore, shaft 210 amounts to about 10 degrees of arc with respect to the gear wheel 282 and the plate in one and reflects the desired position in which the fixed position and is exposed to the cell CR 2 by the appropriate setting Cylinder impulse of console 272 aligned with the photocells. To give up the 40. Of course, instead of the light just described, you can only excite the photocell any other arrangement described above, if the relevant perforations in the gearwheel choose a metric arrangement, which has a linear 282 and the plate 266 to the corresponding photo-increase in the signal from the photocell CR1 returns cells CR 1 and CR 2 are aligned. and the circuit connected to cell CR 1

The gear 282 is similar in shape to that of FIG. 45 and can be arranged so that the linear character side plate 258, in addition to improving the perimeter of the signal,
is provided with teeth which mesh with the If the monitoring zone signal with its gear 242 driven by the motor 236 are approximately 10 ° to the left of the line 283 . In addition, the gear 282 carries the partial starts, assuming that the plate 284 is disk 280, which moves clockwise through the window 290 50, then the mask 266 can be observed, the latter in its the photocell CR 2 free for exposure when the same location on faceplate 230 is fixedly aligned with line 283 by ring 228 so that the cylinder is held.

Since the 35 from. This pointer has a specific position in relation to a threaded hole 269 in the recesses 265 point on the printing cylinder and is aligned to the center each by approximately 22.75 arc degrees from the center of the openings 286 and 267.

The projections 264 on the on an oscilloscope, compared to the ends of the masks 260 and 262 cover a position to the output signal of the cell CR 1 fixed-circular arc of about 2 ° from the end of the respective infeed. If adjustments are required, then mask on and serve to align the 45 masks 260 and / or 262 by means of the direction of the masks in slot 267 to maintain slots 261 and screws 269 so long. If, for example, the mask 260 is set to approximately 8.5 ° until the signals are set in the correct relationship with the radius 263, then there will be one another. Subsequently, the output of the exposure of the cell CR 1 through the opening 286 signals the cells Ci? 1 and CR 2 in a certain through about 10 ° before, since the slot 288 brings the 50 relationship to the signal of the scanner 115 exposure of the cell CR 1 about 18.5 ° to the one, so that the output signals of the cell CR 2 side the aligned center of slot 267 and and scanner 115 initiates the same relationship with aperture 286. At this point the monitoring zone signal is to be had. This can be seen from the fact that the exact location in which the cell hand is made by operating knob 220, CR 2 with respect to cell CR 1 is exposed 55 if gear 242 of motor 236 is not as important as being disengaged that this exposure was brought into one with the gear 282, what happens through the specific position to that through the exposure of the actuation of the knob 234.

If it should be desired to adjust the position of the monitoring zone signal to the ready-to-print position or to bring the same into a special relationship with a finished print, then the degree of the required setting can be read on the index disk 280. Knob 234 is manually operated to disengage gear 242 of motor 236 from gear 282, whereupon knob 220 is operated to rotate gear 282 and side plate 258 along with photocells CR 1 and CR 2 . The extent of the rotation is determined by observing the angle marks on the index disk 280 with reference to the mark 292. This changes the position of the photocells CR 1 and CR 2 to the pointer 224 and the masks 266 and 284 by a certain or certain amount, so that the signals from the monitoring zone and from the cylinder can be generated in a desired location to the impression cylinder and / or to the output signal from the scanner 115. Then the knob 234 is released to bring the gear 242 back into engagement with the gear 282. Alternatively, of course, the motor 236 can also be energized in order to rotate the gear 282 and the side plate 258 together with the photocells in a desired position, the output signals of the cells being compared, for example, with the scanning signal, in order to set the correct signals from a distance Bring the extent of registration. These adjustment devices are primarily intended for the elastic adaptation of the device to different operating conditions.

Circuit details

In this regard, reference is made to FIG. 3 to 5 referenced in which units of the circuit in addition to the different voltages are given, as well as on the F i g. 6 to 8 with graphic representations certain phases of electrical states.

During the rotation of the printing cylinder shaft 210, the masks 284 and 266 release the photocells CjR 1 and CR 2 for exposure by the light source 270, as is indicated schematically in FIG. 3. First, the photocell CR 1, which has a barrier photo-effect characteristic, is exposed to light from the lamp 270 in order to generate the surveillance zone signal.

If the exposed area of the photocell CR 1 increases, the monitoring zone signal increases to the same extent as the current intensity through CR 1 increases. This leads to the transmission of a signal via the line 301 to the base circuit of the transistor T 3 in the monitoring zone amplifier 410. The transistor Γ 3 amplifies this current so that it is largely linear, like the pulse shape "^" in FIG. 6 and 7 shows. If the current coming via line 301 increases, the collector circuit of T 3 changes from -20 volts to approximately +20 volts. The potentiometer P1 is of course set to a certain part of the input current by a diversion in order to prevent Γ 3 from working to saturation. With the voltages shown and with the correct setting of P1, the collector circuit of Γ 3 reaches a peak value of about + 18VoIt at the time when the cell CA 1 is fully exposed without flattening the tip. The thermistor THl and the associated resistors are provided in order to compensate for fluctuations in operation of Γ 3 in the event of changes in the temperature of the surrounding air.

ίο The signal at the collector circuit of the transistor Γ 3 is connected via line 411 to the base circuit of transistor Γ19 in the adjuster 420, to the base circuit of the transistor Γ43 in the cylinder storage unit 510 and to the base circuit of the transistor T 49 placed in the paper web storage unit 520.

The transistor T19 in the preamp pulse shaper 420 is normally highly conductive; but as soon as the positive signal appearing on line 411 has risen by several volts, transistor Γ19 becomes non-conductive. The resistors R 19 and Λ 20 are used to bring the bias voltage on the basic circuit of Γ19 to the desired level. The negative part of the trapezoidal pulse shape - pulse shape "ß" in FIG. 7 - shows this process. The collector of Γ 29 then remains negative until the monitoring zone signal falls below a certain value and Γ19 becomes conductive again. The negative signal is applied to transistor Γ 21, which immediately becomes conductive in order to emit the square pulse “C” in FIG. 7 and “A” in FIG. This positive pulse is applied to the differentiating network consisting of the capacitor C 21 and the resistor R 21. The positive signal at the collector circuit of Γ 21 is also transmitted for a purpose to be explained later via the line 422 to the gate circuit resistor R 39, which is connected to the base circuit of the transistor T 37 in the safety gate circuit. The differentiated positive pulse from the collector of Γ21 is applied to the base of transistor Γ23. The transistor Γ 23 therefore switches off, and its collector becomes negative to emit a pulse, the characteristic of which is determined by the value of the capacitor C 23 and the resistors R 22 and R23. The transistor T 25 therefore becomes conductive due to the negative pulse in order to emit a short positive pulse in its collector circuit via the line 421, as indicated by the pulse shape "β" in FIG. 6, "£>" in FIG. 7 and "ß" in FIG. 8 is shown. This is the pre-impulse; its rise time, amplitude and length are essentially independent of the shape, the amplitude or the frequency of the input signal.

The positive pulse on line 421 is applied via capacitors C 27, C 31, C 40, C 45 and C 51 to the cylinder pulse gate circuit 440, the pass pulse gate circuit 460, the security gate circuit 470, the cylinder pulse storage unit 510 and the passport pulse storage unit 520, respectively. At the gate circuits 440, 460 and 470 for cylinder pulse, pass pulse or security circuit, the positive pulse is passed through the appropriate rectifiers or diodes D 27, D 31 or D 40 to the base of the transistors T27, 31 or Γ 39, while in the cylinder and passport pulse storage units the [ pulse is given to the base of the transistors Γ 47 and Γ53. Each of these transistors therefore receives

a bias. Since the transistors T 27, Γ31 and C 53 are charged positively via the diodes D 45 or D 51 and T39 with the transistors T29, T33 or Γ 41 tiv. Now, however, depends on the speed, arranged in a conventional flip-flop circuit, at which the monitoring zone signal increases; each of the latter three transistors will depend on the speed of the cylinder. With every arbitrary response to the positive pulse on line 5 towards the cylinder position, the condensers 421 become conductive. Sators C 47 and C 53 always point to the same positive

It is remembered that the momentum depends on the value, regardless of the speed of rotation Line 411 to the base of the transistors Γ43 and the cylinder.

The positive pre-pulse is also applied to the base and this signal in turn rises in a linear circuit of the transistors Γ27 and Γ31, ratio to the current flow or the potential 15 around the same - as already mentioned - to the emitter of these transistors accordingly to lock. The potential of these transistors will now regulate. + 20 volts to earth and the negative signal becomes

The transistors T 43 and 49 act as a buffer, placed at the base of the transistors 29 and 33, so as to prevent the switching functions in that each of them is conductive.
Storage units affect the input signals. 20 If the capacitors C47 and C 53 in the normal is the emitter of the Tran- cylinder impulse storage unit 510 or in the passsistor Γ 43 at a potential of - 20 volts, to impulse storage unit 520 is negative to about - 14 a counter bias for the rectifier D. Charge 43 volts, then transistors Γ 29 and D 45 will emit; However, since the emitter is positive and Γ 33 in the gate circuits 440 for the cylinder, in order to follow the signal on the line 411, 25 derimpuls or 460 for the pass pulse conductive, the capacitor C 47 can now be via the DC Charge negative signals to the rectifier D45 in a positive direction and follow the collectors of Γ27 and 7'31 via the resistors signal on line 411. The transistor Γ49 2? 28 or i? 32 to the corresponding bases of the as well as the rectifiers D 49 and D 51 in the pass transistors 7 "45 and Γ 51, whereby each of the pulse storage units 520 fulfill a similar radio 30 the latter is conductive,

The voltage of + 20 volts to the capacitors via line 421, and since the corresponding pre-pulse applied to C 45 and C 51, however, the emitter of Γ 43 and Γ 49 have a less basic circuit of the normally conductive transistor-positive value, the diodes D 43 renT'47 and Γ 53 a bias voltage in positive 35 and D 49 are blocked for the current flow. If the direction, so that each of them blocks for the duration of the emitter of Γ 43 and Γ 49 with the linear rising pre-pulse on line 421. During the monitoring zone signal over the line 411 time in which the transistors Γ 47 and Γ 53 are energized, each of the capacitors will tend, the diodes D 47 and D 53 naturally have C 47 and C 53 more negative than the The emitter concerned borrowed a reverse bias and are not 40 from Γ 43 and T 49. The capacitor C47 starts conducting because the capacitors C 47 and C 53 are always more negative than + 20 volts via the diode D 45 and the resistor. When the transistors 7? 43 to discharge, while the capacitor C53 block with Γ 47 and Γ 53, the collectors of the discharge via the diode D 51 and the counter-disks - 20 volts, so that a current through the stand R 49 begins, as it does the Pulse shapes "E" resistors R 47 and R 53 as well as through diodes 45 and "F" in FIG. 6 show.

The impulse is generated by the con response, the photocell 115 provides a negative capacitor C1 and the parallel resistor R 1 and signal to the grid of the tube Fl in the pass the input impedance of the transistor Π differential pulse amplifier 350. The potentiometer P 2 is used, so that at the base of the transistor Π a natural to the bias voltage and the needle-shaped negative pulse appears. Set the tran- sility level of the tube Vl . Running sistorTl is switched in emitter circuit, and its paper web and cylinder are synchronized, then output signal E ist appears in FIG. 7 shown. This output of this signal at the same time as the output signal from output signal is transmitted via line 302 to CR 2.

The diode R 2 for setting the sensitivity level as D 3 is connected between the transistor Γ 3 and + 20VoIt cathode follower and transmits a positive signal to the transient of the capacitor C2 when switched to the baseline of the signal after passing the line 305 about +20 volts to hai- stör Γ11 in the paper web signal shaper 450.

Line transmitted without excessive distortion Since the input signal is large enough to be the tran-, since the output signal of V 2 has the same sistor Γ 5 to overdrive, the output signal of the 20 has voltage as its input signal, but the latter has a square pulse F, as Fig. 7 shows. much lower impedance.
This pulse is through the capacitor C 5 and At this point it should be noted that the Einsteiden resistor R 5 differentiated and applied to the base development of R 2 a balance of different states of the transistor Γ 7 to block the same. Permitted in paper web and register stamp. The transistor Γ 7 therefore provides a negative 25, for example the signal response of the cell 115 pulse G, such as F i g. 7 shows. This pulse is differentiated from the difference in the response to light from through the capacitor C 7 and the resistances of the paper web and from the register mark , and R6 and Rl. The differentiated impulse if the paper web and its corresponding one is further amplified by the transistor T 9 , register marks different colors, intensities in order to have a needle-shaped positive and tinting on its collector, must emit a geven impulse for a compensation, like as C in F i g. 6, "H", in to be taken care of. Given the F i g. 7 and C in FIG. 8 shown. This impulse is factors of the paper web and register mark, essentially independent of the shape. Ampli- man recognizes the described scanning rate and frequency of the input signal. also gets on signals of opposite character

The output from the collector of the transistor T 9 35 can respond as those just described. In the case of a positive pulse spike, the line 431 leads to other conditions, i.e. if the paper web via the capacitor C 9 and the diode D 9 to the dark and the register mark is light, the base of the transistor T 29 in the cylinder pulse character of the cell 115 and the tubes Vl gate circuit 440 placed so that the transistor φ29 and V2 derived signals opposite to the non-conductive. The collector of Γ 29 will therefore be 40 just described, so that a negative negative, and a corresponding pulse is transmitted to the pulse via line 303.
Base of the transistor Γ 27 placed to the same The transistor TIl is such an npn-type to make conductive. This negative pulse is evenly and conducts when responding to a positive signal from so through the line 442 to the base of the transistor of the line 303, the capacitor CIl and the Γ35 in the safety gate circuit 470. The 45 resistor R 12. If negative signals are to be received, the latter is supposed to work afterwards, then the transistor Γ11 will be spoken through. In the meantime, the KoI actuation of the switch 51 is blocked, as the detector of the transistor T 27 is positive, and this will be clarified positive, but the results achieved by the former 450 tive impulse is sent to the base of the transistor Γ 45 in the same regardless of what is applied to the cylinder pulse storage unit 510. The 50 type of pulse coming from line 303.
The DC level of this positive pulse is increased by +40 volts when transistor Γ11 responds to a positive signal applied to resistors R 29 and R 28 on line 303, but a negative voltage is used at its collector circuit the amplitude of the pulse through this increased voltage, which would be reduced to the base circuit, as the pulse shape "/" is placed in 55 of the transistor Γ13, around the same conductive Fig. 7 shows, in which both the respective ampli to do.

If you now return for a moment to the transistors 29 and Γ 33 when responding to the paper web pulse shaper 450, then positive pulses from the lines 431 or 451 you will remember that they are so arranged to become non-conductive and that the collector circuit could be denied that it swings negatively both positive and negative voltage of both transistors. These input signals on line 303 are processed. To achieve voltage the transistors Γ27 or Γ33, the switch S1 is provided, conductive, and a positive pulse is applied to the Leitunwelcher in the position shown, the earth to the gen 441 or 461, to the transistors Γ 45 emitter circuit from TIl and + 20VoIt to the or Γ51 to make it non-conductive. The relevant diode DU connects, the latter by 45. Diodes D 45 and D 51 are connected in such a way that +40 volts is biased, the capacitors C 47 and C 53 are prevented from being applied to one side, the one from R 13 and R 14 existing voltage divider. to further discharged in the positive direction, such as addition, the switch S closes -20 volts to the already explained and as shown in the waveform other side of the diode D Il through resistors "K" in Fig. 7, showing the different voltage RU and R12 on. With this arrangement there is 50 values at the emitter of the transistor Γ43, see the connection point of the resistors R 12 and is visible. A similar state as at the R13 at a potential of about +20 volts, while the emitter of the transistor T 43 also occurs at the emitter, the base circuit of Γ11 is somewhat more negative, so the transistor Γ 49 occurs.

If one assumes that the paper web register sudden drop in the emitter voltages is correctly synchronized in the mark and the paper web signal is equal to the voltage of the capacitors C 47 and 5 at the same time as the cylinder CSS occurs, the diodes D 45 and D make 51 non-conductive, emits impulses, then both capacitors are terminated, whereby the discharge of the capacitors C 47 and C 47 and C 53 at the same time to the same voltage C 53 is terminated. This voltage is connected to that which is maintained by the distance that the diodes D 45 and D 51 until the arrival of the post-printing cylinder 150 and the paper web 30 of the best readjustment pulse, so that the readjustment pulse on the line 421 begins for io remaining cylinder rotation the capacitors have covered, as well as remain on the voltage of the following impulses C 45 and C 51 , on sen depends on the cylinder and paper web. The conweiches were charged in the same way as the capacitors C 47 and C 53 are therefore exemplified by "E" and "F" in FIG. 6 show. The proof will be at earth potential if both result that the capacitors C 47 and C 53 arrive for 15 pulses at the time the cylinders of tension remain, which of those about exactly 10 arcs from the beginning des overrides, which has turned off by the monitoring zone signal in wachungszonensignals as it was reached at the point in time when the pulses from parts of the waveforms "E" and "F" relating to the cylinder and paper web at the storage units 510 the first cylinder revolution , in FIG. 6 or 520 arrive. 20 represent.

By adding 5 bar to control the sensitivity of the combiner's particular DC voltage to a channel amplifier 530 and stabilizing the gain for the differential amplifier 530 , the operating level becomes any given setting. This gets that channel adjusted to the other, and one gets a means on hand to adjust the inner one, an equivalent for the movement of the pa reinforcement and thus the degree of response to the cylinder, or vice versa. As can be seen from any given view of the amplifier 530 , by changing the preload output signal one comes to compensate for different operations on one of the tubes V 5 or V 6 due to the conditions of the press, such as e.g. B. different cylinder movement of the slide from P 5 to the same of sizes and translations in the compensation device.

The slide ensures that the servomotor 80 cannot be moved when the potentiometer P 5 is activated in both directions; when moving in the will.

In one direction, tube V 6 is positive. It can be seen that, from the point in time when the bias voltage, when moving in the other 20 capacitors C 47 and C 53 through the readjustment direction, a negative bias voltage is applied to the same initially set as previously lays down. If one leaves the slide - as shown here - the discharge of which is essentially in the middle position, then the same measure takes place between the slide, so that in the difference and the cathode of V 6 no voltage gradient is passed through the transistors T 55 and Γ 57 winds, so that the bias voltage of both tubes V 5 25 formed path is regulated in the same way and V 6 is the same. Optionally, a DC voltage can be added to the guard zone signal formed by the transistors Γ 59 and Γ 61 in order to achieve a practically stable, balanced output when the signal is sent to one or the other of the signal to the solenoids 535 and 536 in the Ren of the two capacitors C 47 and C53 laid hydraulic servomotor 80 to lay. The valves are used to adjust their tension, or the hydraulic system does not come into action.
Capacitors are adjusted in a different way, at the moment when one of the capacitors changes in each of them as desired, C 47 for example, as the result of the occurrence of voltage. These types of electron-fens is connected the cylinder reference pulse, fresh biasing give a very versatile during Kondenator C 53 continues to discharge, arrangement for adjusting the position of the color 35 as shown in F i g. 6 is shown for the second cylinder revolution to the previous pressure in register, is to be applied to the differential amplifier 530 , in both directions around which an error signal is generated. The one in the one path of the desired dimension. Amplifier 530 begins amplification immediately

The transistors 55, Γ 57, Γ 59 and Γ 61 continue to increase the gain in the other path via one of the usual DC-coupled 40.

So you can see waveform "G" in FIG. 8 shows. The amount of ken flowing in through the valves will be determined so that transistor Γ 35 becomes non-conductive when oil is proportional to the deviation between either line 442 or 462 is positive because of the cylinder pulse and the paper web pulse and 15 that for i 35 , R 36 and i? 37 selected ohmic thus proportional to the misregistration between resistors and the paper web and printing cylinder connected to them. As the device tensions. If the transistor Γ 35 non-conductive reads the error only once per revolution, the input signal to which the setting oscillates after receiving both the cylinder base circuit of the transistor Γ37 in the negative direction as well as the paper web pulse and during the 20 direction to the potential of the Earth. The monitoring remaining revolution is constant as it is the wave zone signal from the collector circuit of T 21 form “G” in FIG. 6 shows. coupled to the base circuit of transistor Γ 37,

If the error occurs, as shown in FIG. 6 in which and this positive signal is explained about the resistance following revolution, has changed what .R 39 on the base circuit of the transistor Γ 37 gesich in the arrival of the paper web pulse in front of 25 hold. The resistors 2 38, R 39 and 40 form the cylinder pulse, then the piston will stand in an arrangement somewhat similar to that of the hydraulic cylinders 70 at a speed R 35, R 36 and R 37, but they are so actuated which is arranged proportionally to the new error signal that the transistor Γ 37 is conductive. The capacitor C 53 is connected in this case to that of the capacitor C 47 when the input signal through the resistor R 38 is connected to a potential which is more negative than 30 negative or to the potential of the earth, that of the capacitor C 47. The output if the transistor Γ 35 non-conductive will. Normal signals to the coils 535 and 536 are now wisely so the transistor Γ 37 is reversed at the beginning of the previously explained, and the working cycle is conductive.

As already mentioned, the transistor

The system also includes certain protective devices that are conductive when both of its input lines indicate a very faulty working 442 and 462 negative or to the potential of the earth way of the device. This includes the 40 swing. The transistor Γ 37 can therefore only become non-conductive when the fail-safe safety gate circuit 470 and the cut-out occur when the paper web pulse set safety relay 540, which causes the failure, to make Γ 33 non-conductive. Then the signals or pulses from the cylinder or from which the collector circuit oscillates from Γ 35 positive to determine the paper web. So if one of the if the same starts to conduct because the two above signals fail, this gives the wrong display 45 transistors T 29 and T 33 become non-conductive; Its a big mistake because the amplifier 530 does not swing the collector circuit to +20 volts, as the required signals from the accumulators waveform "G" in FIG. 8 shows.
510 and 520 respectively. The transistor Γ 37 is therefore non-conductive, since the wrong correction is carried out in one or the other input signals through the two resistors R 38 direction, depending on the intermittent 50 and i? 39 are now positive. A negative signal, which would then lead to a spoilage of the prints voltage therefore appears on the collector of the; It can also happen that the transistor T37, like the first pulse in FIG. 8, shows the compensating roller 50 to the limits of its waveform "H". This negative span stroke is actuated. The misfiring safety precaution oscillation is done by the diode D 37 should the device or the printing machine block at 55. Before the transistor Γ 37 is switched off The cause of the failure to say the impulses received from the cylinder and paper web can be identified more easily. be like the waveform at the first cylinder

It will be remembered that an adjustment pulse revolution in FIG. 8 shows. If each input on line 421 to the base circuit of the trans- 60 signal to transistor Γ 37 remains negative, sistorsr39 will conduct, leaving the same non-the same as the second, third, and conductive. The collector circuit of the straight line T 39 comprising the fourth cylinder revolution oscillates negatively, as is the case with the first pulse in the waveform "i?" In FIG. 8 shows.
Waveform "/" in FIG. 8 shows. The transistor is now assumed that the cylinder pulse and T41 is therefore conductive when the negative oscillation 65 paper web pulse is received before the voltage in the collector of T 39 to the base of the monitoring zone signal is at the end, then ίΓ41 is applied. You will also remember that the transistor Γ37 switched off, as already explained the adjustment pulse on the line 421 was the Tran-. Then changes if the transfer

wachungszonensignai ends, the input signal to the resistor R 39 from positive to negative, and Γ37 begins to conduct again, as shown by the cessation of the pulse in the waveform "H" . It is this negatively oscillating rear end of the monitoring zone signal which causes the collector of Γ 37 to become positive again and to transmit a positive signal via the capacitor C 37 and the diode D 37 to the base circuit of the transistor T 41 . ^;

The transistor T 41 is therefore non-conductive, while the transistor T39 is made conductive, so that the collector circuit of the transistor Γ 39 is positive to give the line 471 a corresponding bias, but which does not affect the state of the transistor Γ 63 in the misfire safety relay impaired. It should be noted that the negative oscillation applied to the line 471 , while the transistor Γ 39 is non-conductive, goes through the filter circuit consisting of the resistors / 63 and R 64 and the capacitor C 63 during each revolution of the cylinder. This prevents negative signals of other than a certain duration from affecting transistor Γ 63. The transistor T 63 is thus prevented from becoming conductive during low speeds of the press.

With the next adjustment pulse on line 421, the collector circuit of transistor Γ 41 swings positively to make transistor Γ 39 non-conductive, but the negative oscillation in the collector circuit of Γ 39 is of such a short duration that it only then turns transistor T 63 on can make when the monitoring zone signal ends in order to reverse the state of the transistor T 39 again during normal operation.

If one of the aforementioned signals from the cylinder or paper web fails, the transistor φ 35 does not change its state, and therefore the transistor φ 37 remains conductive during the entire monitoring zone signal. So if one assumes, as is the case for the second cylinder revolution in FIG. 8 shows that the cylinder reference pulse fails, then the transistor Γ 35 does not conduct, as the waveform "G" shows. This is why the transistor Γ 37 does not become non-conductive during that rotation, as the waveform "H" shows. The collector circuit of Γ37 remains negative during the entire revolution, and the capacitor C 63 charges itself negatively from the collector potential of Γ 39 in order to make the transistor Γ 63 conductive. The collector circuit of T 63 becomes more positive, as shown by the waveform "/ ?!" in Fig. 8, in order to render transistor Γ 65 non-conductive approximately in the middle of the increase in the voltage oscillation at the collector of T 63 , as the waveform does L in FIG. 8 shows. The relay 545 is therefore de-energized and switches its armature from the contact 547 to the contact 549. As a result, a relay, not shown here, is energized, which switches the coils 535 and 536 of the differential amplifier 530 to a bridge circuit, not shown here, whereby the regulation of the entire press is made possible by hand in a well-known manner.

At the third revolution of the cylinder, as shown in FIG. 8, the scanning pulse is received after the monitoring zone signal has ended. It can be seen that T 35 is turned on when the inputs to both lines - 442 and - become negative. However, since the input signal on the line 482 has already been converted into a negative value, the transistor T 37 cannot be switched off, the line 471 remaining negative in order - as already mentioned - to make T 63 conductive and the relay 545 to be de-energized leave.

At the fourth cylinder revolution, as shown in FIG. 8, the paper web pulse either does not occur at all or it is not received. However, when responding to the readjustment pulse - as already explained - transistor Γ35 becomes non-conductive. If afterwards the transistor Γ 35 fails to become conductive, the transistor T 37 remains conductive and the line 471 assumes a negative potential for a long enough time to change the state of the capacitor C 63 and to turn on the transistor Γ63 and thus making the relay de-energized. The results already described lead to the press being switched to manual control.
