- the form web has in a manner known per se, e.g. generated by printing Markings, the optical reading of which corresponds to the desired form length Control signal triggers; the movement is thereby known by a Control electronics that control the actual value of the feed trigger point with its Compares the setpoint and uses the difference to control the drive.
- the device 1 shown schematically in FIG. 1 has a first guide 12 for the form tracks B 1 and an optional (broken line) second guide 14 for a second form track B 2 .
- the number of guideways is only limited by the design and the number of form tracks to be processed. If desired, three or more form paths could also be merged in an analogous manner (not shown), provided that this is spatially possible in the given case.
- the number of webs processed simultaneously with a device according to the invention is not regarded as critical and is within the professional discretion.
- the guides can be known Be arranged converging one above the other. It is in use of more than one roller (and simultaneous processing of more than one form web) not essential whether the guides each make an angle with the horizontal include or one of the guides runs approximately horizontally. Using A single form web can guide 12 horizontally or at an angle be arranged to the horizontal. The size of this angle is again in the range of professional discretion.
- the form web B 1 and any further form web which may be present are fed to the device from a source, not shown, for example a magazine or a longitudinal separating device for a double-sided printed form web.
- a source not shown, for example a magazine or a longitudinal separating device for a double-sided printed form web.
- Each form web lies on the side of a guide 13 or 15 (only the guide in front is shown).
- Each form web runs between the associated driven roller 182 or 184 and the pressure device attached to it under slight pressure of typically 50 - 500 g, e.g. the non-driven contact or idler rollers 192 or 194 or similarly acting pressing devices to the cross-cutting device 11, which e.g. in on known type as "guillotine" with a cutting bar or knife and one or two cutting edges, can be designed as a rotating knife or the like.
- the cross-cutting device 11 which e.g. in on known type as "guillotine" with a cutting bar or knife and one or two cutting edges, can be designed as a rotating knife or the like.
- several contact rollers can be used for each roller and / or this by means of the same or similar effect, e.g. adjacent feathers, Brackets or the like can be replaced or effectively supplemented.
- the roller 182 or 184 is equipped with an associated drive 162 or 164, e.g. one Electric motor, the activity of which is regulated by a controller 17 in order to to lead at least one form web to the cross cutting device 11.
- an associated drive 162 or 164 e.g. one Electric motor, the activity of which is regulated by a controller 17 in order to to lead at least one form web to the cross cutting device 11.
- the structure of the driven roller 182 in FIG. 2 is based on a semi-schematic one Sectional view explained.
- the roller has a one-piece and continuous Main axis 20 made of a rigid material, typically steel, aluminum or the like, which are rotatably guided at both ends 201, 202 in the bearings 204, 205 and on one side, here e.g. the end 201, is connected to a drive motor, not shown.
- Every sleeve typically consists of a rigid material such as steel, aluminum or thermoset and is provided with a friction lining 219, 229, e.g. made of an elastic polyurethane (e.g. Vukollan® from Bayer AG) or from a coating of fine-grained hard material provided in a suitable matrix material.
- an elastic polyurethane e.g. Vukollan® from Bayer AG
- the associated pressure roller lies on each sleeve in the area of its friction lining 219, 229 29a, 29b in order to adequately close the form web against the friction lining press that the form web (not shown in FIG. 2) when the (in Fig. 2, not shown) drive is transported practically without slippage.
- the two sleeves 21, 22 are in the region of the center of the main axis 20 through the differential 24 connected to each other, as shown enlarged in Fig. 2a.
- the differential 24 consists of two drive bevel gears 211, 221, which act as bevel gears formed and each connected rigidly to the associated sleeve 21, 22 are.
- the operative connection of the drive bevel gears 211, 221 or with this rigidly connected sleeves 21, 22 is carried out by two also formed as gears Differential bevel gears 261, 262, which are freely rotatable about the auxiliary axis 28 and are engaged with the drive bevel gears 211, 221.
- the auxiliary axis 28 lies in a transverse bore of the main axis 20 and is by the Rotation taken, i.e. rotates in the radial direction.
- the auxiliary axis 28 can be axial be rotatable, but this is usually of no practical importance. It is essential that the differential gear 24 only comes into effect when on the form web adjacent sleeves 21, 22 are not equally involved in the transport. Such an inequality can e.g. then occur if contamination occurs during continuous operation due to paper dust or the like, which would result in the form web not exactly straight anymore, i.e. perpendicular to the cross cutting device, runs. In in this case, the differential 24 causes an immediate correction and ensures therefore also in continuous operation with typical running speeds of the form webs reliable guidance of the form web from 1 to 4m / sec.
- a preferred control or regulation of the drive of the main axis 20 is shown in the diagram of FIG. 3.
- the electric motor causing the drive is controlled in such a way that the initially stationary form web first accelerates during a start-up phase B acc and is then guided through the movement or feed phase B mov until the start of the braking phase B br at a practically constant speed.
- the transition from phase B mov to phase B br is used and the braking process is dimensioned such that the form web is exactly in the position controlled in the usual manner, for example by printed markings Cross cutting device is positioned.
- the reading can be carried out in a manner known per se e.g. through optical Reading of the marking on the form web can be triggered.
- the movement will controlled by control electronics, the actual value of the location of the trigger point compares it with its setpoint and uses the difference to control the drive.
- FIG. 4 shows a broken part of the guide 42 of a device according to the invention with the form web 43 lying thereon, which has a center line M and a Width B has.
- the edge-side guides 45a, 45b are at a distance L in the running direction (Arrow A) located in front of the driven roller 44, the distance L is preferably at least as large as the width B of the web 43
- Pressure rollers 49a, 49b are arranged symmetrically to the center line M of the form web and press the form web against the roller in the area of the friction linings is connected via the axis 40 to the drive 46 and the actuation of the roller in controls in the manner set out above.
- the exemplary embodiment set out above serves for explanation and not for limitation of the invention and generally provides an apparatus for processing at least a form web by continuously or intermittently feeding and cutting the at least one form web; the device has at least one to a cross-cutting device Guided tour for the at least one form web. If more than one form path is to be processed, the number of tours is naturally larger accordingly; the device has means for controlling the Feed the form web and at least one driven roller, which is transverse to the Working direction extends over the working width of the device and with at least one Pressing device, e.g.
- the driven roller has a continuous main axis that only on one Side is connected to a drive for rotation of the continuous main axis; this main axis carries at least one pair of cylindrical rotatable about the main axis Sleeves connected to each other via a mechanical or differential gear are related.
