Description

Apparatus for Treat a n it pliotor, # ra phical Sc hicht- ma ter IALS. The invention relates to "an apparatus for treating a photographic material with a horizontally arranged, rotatable drum, at the bottom of which the layer material is washed over by a liquid known to arrange Patent 1,180,599, the material on the inner wall of a cylindrical drum, which operates in a substantially waairechten position and rotated about its longitudinal axis after the developing solution has been introduced into the drum. the drum has end walls that prevent the Liquid flows out of the drum during the development process, and central openings through which a newspaper for the development liquid passes into the drum. At its lower end, the drum rests on mechanically driven rollers e.g. a film constantly about the development flow in the circumferential direction of the `drum. The film is inserted and removed through an opening 4 in the end walls of the drum. Instead, the drum with its liquid content can also be lifted out of its operating position and the film can be removed after the liquid has been poured out. The object of the invention is to provide a device which can be operated in a simple manner for the uniform and precise treatment (developing, subsequent exposure, etc.) of a photographic layer material of any length, which can be carried out automatically in accordance with a selected treatment program In a device of the type specified above, the bottom of the interior of the drum is connected at one end of the drum to a fixed line system for the liquid via a liquid channel which forms a drainage path through which the entire liquid content of the drum can flow out of the drum under the action of gravity . This fluid channel, which is a sliding, but fluid-tight coupling between the fixed line system and the rotating drum, is located with its upper end below the lowest point of the drum base or at most at the same height as it. Preferably, it is elastically slidable on the outer peripheral edge of the open drum at its end and extends around the lower half of the drum circumference by less than 1 80o around so that the drum out of the channel can be lifted out.

In a further development of the invention, the fixed line system also be connected to the other end of the drum and designed such that the liquid flows axially through the drum and the channel. this has the advantage that only a limited amount of liquid is required, which repeats through the drum can be rolled. The directions cbr rotation the drum and / or the axial liquid flow can be reversed repeatedly will. A treatment cycle controlled by a program control device is preferably used automatically filled in in individual steps. The Tromiael can be translucent be so that the photographic material 'during the rotation of the drum of a irradiated external light source and can thus be exposed a second time.

One or more long strips of film can be wound onto a reel assembly having a plurality of axially spaced coaxial reels joined together at their ends. The outside diameter of the assembly; is smaller than the inside diameter of the drum. When the film hits, this arrangement, consisting of several reels, is brought into the interior of the drum by rotating it; the entire reel assembly; along the bottom of the drum; rolls while at the same time the film is washed over by the liquid. The invention will now be explained in more detail using a preferred exemplary embodiment. The drawing shows in FiG. 1 is a perspective view of a device according to the invention; Fig. 2 is a section through the development part of the apparatus of Fig. 1 along the plane 2-2 in 'i;3; 3 shows a section through FIG. 2 along the plane 3-3; FIG. 4 shows the schematic arrangement of the components of FIG Before--: ichtun :; r; emäB FiG. 1 ; FiC. 5 is a vector diagram showing the various possible relative movements between a film recorded in Greed device according to: @ FiG. 1 is being developed, and one Lnt @ -; icklurigsflü igkeit shows; Fig. 6 is a front view of one of several reels loaded standing arrangement for the device according to Figure 1 for Developing a filmstrip; and FiG. 7 the arrangement according to Fi:;. 6 while in a modified embodiment of a drum for the device according to FL: -. 1 is located. As shown in FIG. 1, the previous year has a direction Housing #_ on which is mounted on legs 9 and into a Reagent supply part 10, a development part 11 and a Steuerunt @ part 12 is divided. Hot and cold Water is fed into the device via inlets 13 and 14, respectively Directed. The two input currents graze in a more regulated manner Tit in the rear section of the control part 12 mixes 9 whereby an output current is created which opens up a selected Tf @ mperatur is kept and as a '2 temperature serving means. This output current is generated by the Parts 10 and 11 t_, led (to temper these parts) and then to a drain. The same tempering water can also be used in development Rinse off any films and file various files Clean device. The reagent supply part 10 consists of nine f,; Eicharti.gen cylindrical stainless steel containers with open Top side for various reagents that are to be used in a l # ntuicklurgs cycle for a film. These containers are equipped with nine corresponding liquid level indicators 1? coupled, which are arranged in front of a board 18, on which a number of numbered vertically spaced horizontal alignment lines 19 are drawn, which extend across the entire board and indicate the volume of liquid in the containers are housed in a temperature control tank and surrounded by temperature control water, which keeps the reagents inside the container at the selected temperature.

The nine i @ eaJenzien storage containers are by appropriate and optional to be operated bottom valves connected to a manifold, which contained in them ! # liquid leads to development part 11. This part is essentially all in one box-like, light-tight housing 25 housed, the interior of which from above or from below through a rear hinged upper lid 20 and a rear hinged lower 1'latce 2? to .-; is similar. As later will be described in detail, finds the real development of the photographic Material, such as roll film, plate, or prints, inside the developing section 11 instead.

The device according to fit ;. 1 is a developing device in which a batch of film material, for example, is introduced into the device and completely processed in a single location before a next batch is developed. Such a device must therefore be distinguished from photographic processing systems in which separate film parts are fed one after the other into and through a series of processing stations, so that each processing step takes place at a different location and the different film parts are simultaneously subjected to different processing steps 1 can initially comprise a temperature control step, then a sequence of steps, whereby the film is exposed to various reagents in the device, and a sequence of steps alternating with the reagent processing steps, wherein the film is washed or rinsed with temperature-controlled water. In each such machining cycle, the type, the time of the start (after the time IJull) and the subsequent duration of each step can be determined by a program which is recorded on a plastic card 30 which is inserted into a slot 31 of an automatic electrical control device in the control part 12 is mounted on the inside of a door leaf 32 swinging to the right, so that it is in front of the members that control the temperature of the water inlet. The operation of the device according to a program recorded on an inserted card is initiated by pressing a start button 33. When the operation of the device has been brought under the influence of the program control, the plastic card 30 is automatically gradually drawn further into the slot 31 at a speed which is determined by the recorded program itself. If desired, the device can be controlled semi-manually instead of by a program. For this purpose, a set of buttons 35 is provided, each of which, when pressed, initiates a corresponding four of the following operations: 1) Second exposure; 2) Tempering the device with tempering water; 3) washing out the device by this water; and 4) draining the system.

The automatic control device used here, programmed by a card is commercially available (e.g. from Otto Ramstetter) and provides linen Part of the invention.

In the development part 11 according to FIGS. 2 and 3, in the outer housing 21 there is an inner light-tight housing 40 with end walls 41, 42 and side walls 43, 44 which enclose a rectangular space 45 = the top and bottom through the upper cover 26 and the lower batten 2? is completed. The walls of space 45 are offset inwardly from the walls of housing 25 to provide a pair of end work spaces 46, 4? and to create rear and front work spaces 48,49. The rectangular space 4.5 is divided into an upper chamber 50 and a lower chamber 51 by a translucent plastic partition wall 52, which represents a floor for the chamber 50 and is slightly inclined from front to back. Inside the chamber 50 is a transparent plastic developing drum 55 made of, for example, methyl acrylate resin and having open ends spaced from the end walls 41, 42 of the rectangular space 45. The drum 55 rests with it its axis horizontally on two pairs of rollers.56 located at opposite ends of the drum so that the two rollers in each pair abut the drum at points on opposite sides of the drum base. In each pair of rollers, the front is one Idler roller and the rear one drive roller. The drum 55 can dents around its axis either clockwise or counterclockwise via a connection 63, ie the two drive rollers, their shafts 57, pulleys 58 on these 'dents and drive belts 592 which the pulleys 58 with pulleys 60 on a shaft 61, rotated by an electric motor 62 (Fig. 4) in the working space 48. The Hotor is connected to the We All 61 coupled and reversible in its rotation by a relay-controlled reversing switch 65. To improve the frictional contact between the drum and the drive rollers, the drum 55 is weaved by rubber bands 66 which engage corded sections (not shown) that extend around the drive rollers. If desired, the rubber bands 66 can run in knurled annular grooves of the rollers, which allow axial wandering of the drum as it rotates; impede.

The drum 5 .5 has in its interior two pairs of similar horizontal rows of axially spaced film holding hooks 70, which are distributed around the inside of the drum so that the two rows of beacons that form each pair are less from each other than a semicircle away. Each of the halls 70 is formed from a piece of wire c-e, the opposite ends of which are countersunk in the drum wall. They have a portion between their ends which is bent so as to form an inwardly directed angle towards the other row of hooks in the same pair of hook rows Are to be wound, are held within the drum 55 by bending them and then inserting them with their opposite ends into the opposite rows of nails To ensure an even hand grip of the piece of film on both sides, the hooks 70 keep its edges away from the inner wall of the drum.

Outside the drum 55) there is a newspaper system for film treatment liquid, which is fed through this system into the interior of the drum 55 in the following manner. An elbow 80 for supplying the liquid leads from the reagent reservoir 10 (Fig. 1) through the housing 25 and to the light-tight housing 40 to be connected to the upper chamber 50 through a channel or opening 81 extending through the end wall 41 of the housing extends. Liquid emerging from this opening is directed to the bottom of the drum 55 from the left of two channels 85 and 36. 2 and 3, the channels 85 and 86 are in the form of rubber troughs held on the insides of the end walls 41 and 42 by screws 87 passed through relatively thick bases 88 of those parts and then into the end walls get lost.

Each of the trough-shaped channels 85 and 86 is curved in shape in the circumferential direction of the drum. In the axial direction of the drum to extend to and through the corresponding one of the two opposite open ends of the drum. The front portions of the channels 85 and 86 are in the form of resilient flaps 89 which lie under the bottom of the drum and extend up along the sides thereof over an arc less than a semicircle. Each such lip 89 has an upwardly facing surface 90 which abuts the outer surface of the drum over the entire arcuate portion of the lip. The channels 85 and 86 lie in the vertical direction on the walls 41 and 42 that the weight of the drum 55, before it is placed on the rollers 56 in the chamber 50, presses on the zips 89 and deflects them elastically downwards by one establish a liquid tight seal between the upwardly facing surfaces of the lip and the outer surface of the drum. The lips can slide on the drum circumference so that the seal between the drum and the channels 85 and 86 is maintained even when the drum rotates.

The channels described thus form fluid couplings from one stationary to a circumferential part between the stationary line system outside the drum and the rotating interior of the drum. Because the left Channel 85 located under opening 81 for manifold 80 is from this manifold Liquid conveyed in is directed from this channel to the inside of the drum. If the liquid thus conveyed is a reagent, it becomes a predetermined one limited ", narrow rather than fed in a continuous stream. To ensure dah this limited amount of reagent evenly and bit most efficiently that Film piece 71 treated, the reagent is passed through in a closed circuit the drum, which is closed as follows.

A fum-pe 95 driven by a motor (in the left end work area 4ö) has an impeller 96, which is in a pump chamber 97 between newspapers 98 and 99 which open into this chamber. The newspaper 98 extends extends through the end wall 41 of the drum chamber and forms on the inside thereof W; nd an opening 105 above the channel 85. The newspaper 99 connects the pumping chamber 97 with a drain line 106 and one end of a return line 107. A similar one motor driven pump 110 (in the right end work space 47) is with a Impeller 108 is provided, which is in a pump chamber 109 between Leituren 111 and 112, which open into this chamber. The newspaper 111 extends extends through the end wall 42 of the upper chamber 50 and forms on the inside thereof Wall an opening 113 above channel 86. Line 112 connects the pump chamber 109 with a drain line 114 and with the other end of the RüMaufleitung 107. the Both pumps 95 and 110 can optionally be operated and reversed so that they pump liquid either up or down. The two drain lines 106 and 114 can optionally be opened and closed by means described later will. These two drainage lines lead to a common drainage line 115 (Fig. 3).

If the liquid in the drum is His reagent, this will be Reagent w: circulated repeatedly. For this purpose, the two discharge lines 106, 114 closed and the pumps 95 and 110 operated selectively so that one up and the other promotes downwards. When the pump 95 is actuated it goes down promotes, the reagent flows axially from right to left through the drum 55 and then runs from left to right through return line 107 and then upwards through the pump 110 and the drum. When the pump 110 is delivering downwards, the reagent flows axially from left to right through the drum and then from the right left through return pipe 107 to through pump 95 and back into the drum to run away.

Instead of adding a certain amount of a reagent, the elbow can 80 to supply the drum 55 with a continuous stream of temperature control water, to wash or rinse the film 71 in the drum. In this case the Pump 110 actuated to pump downwards and pump 95 to pump upwards, and drain lines 106 and 114 are both open. The upward pumping effect of the Pump 95 prevents the temperature control water from flowing through opening 105. Accordingly will the water flow from the Ab, .rärtspumpwirl, -ung of the pump 110 axially from the left to pulled right through the pump 55, to then through the drain lines to the drain pipe 115 to flow.

'° lie from the fif-. 2 and 3, the upper limit areas were left the channels 8; and 86 below the level of the floor of the interior of the Trom: .iel 55. The floors of ÖfnunZen 105 and 113 also ran below the floor of the interior of the drum. The mentioned channels form 2lüssikeitsweg, through which the entire liquid content the drum can flow out under the influence of gravity. To such a one To ensure fluid flow, the channels from the drum do not bulge must necessarily run at an angle to ab @ Järts, but can also be at Lleicher Höhe with the lowest point of the interior of the drum.

To at least one such flowed through under the influence of gravity The drum is a useful part of maintaining the liquid path. That Presence of at least one such rilü: - # igheitsweges prevents the development a stagnant pocket of liquid in the course of the reagent solution or in the water flow axially to the drum and in the direction of the fluid path mentioned. The usage of two such fluid pathways prevents the formation of such a pocket in both axial directions.

As already described earlier, are in the reagent storage part 10 (Fig. 1) stored reagents by heated water that tempered the container for the reagents surrounding it. It is also desirable that the Drum chamber 50 and the reaUens put into circulation again are tempered. To this end a stream of tempered water is passed through a newspaper 120 to the inside of a jacket 121 passed, which surrounds the return line 107. This water moves from right to left through this jacket, around the one running through "the return pipe Maintain reagent at the chosen temperature. At the left end of the coat runs the tempered water up through a riser 122 to over the top surface the translucent partition 52 to flow, wherein the temperature control medium moves downwards over the slight incline of this surface to a drain 123 # der is connected to the drain pipe 115. While it is across the bottom of the drum chamber 50 flows, the heated water temperature this chamber. The drain 123 serves to both the tempering water supplied from the pipe 122 and any other Liquid (reagent or water) that happened to be in the chamber due to overflow should be injected into the chamber via the sides of channel 85 or 86, derive from this chamber 50.

The return line 107 and the jacket 121 are arranged under the partition 52 and are located in the lower chamber 51, which is formed within the housing 40 by this partition. Furthermore, in this chamber there is an arrangement of four fluorescent tubes 1309 which extend axially between fluorescent tube sockets 131 which are mounted on the lower plate 27 which is provided with a rear hinge. This panel is normally in the closed position (as shown) and is held in that position by fasteners (not shown). The four fluorescent tubes 130 are divided into two separate pairs of tubes located on transversely opposite sides of the jacket 121 so that Each tube can radiate unhindered through the wall 52 into the drum 55. All four tubes can be ignited simultaneously by the optional actuation of a relay-controlled switch 132 (Fig. 4). The light from the ignited fluorescent tubes falls through the plastic partition 52 and the transparent wall of the drum 55 (which then spins but does not contain any liquid) on the piece of film? 1 in the drum, thereby causing a second exposure of the piece of film. Since the piece of film rotates in a closed path and the light from the fluorescent tubes 130 is at several different angles of incidence falls around this path, the piece of film receives a uniform second exposure even with wrinkles or other defects due to its position within the drum.

Fig. 4 is a schematic diagram of the overall arrangement of the apparatus of Fig. 1. The fluid, electrical and mechanical connections are represented by solid, dashed and dashed lines, respectively. As shown in FIG. 4, the hot and cold water at the inlets 13 and 14 is fed to a motor-driven mixing valve 140 in order to be mixed therein and then passed out again as a temperature-controlled stream. This flow then passes through a manually adjusted throttle valve 141, an electromagnetically operated shut-off valve 142, and first and second heat control members 143 and 144 (thermocouples). The valve 142 is controlled by the control device 150 either semi-manually or by a program induced ornamental signal (which comes from plastic type 30) operated to open when water enters the device should be directed. The control members 147 and 11l-4 are connected to the motor of the mixing valve 140 by appropriate de Sii; nalriicldiopplungspfad 145 and 146 coupled. Each this control element speaks to the temperature of the flowing water to Tiber the corresponding ßücl.lcopplul spfad to deliver a signal that Accordance with the temperature fluctuates from the Control device is sensed to the I, Iischvontil 140 to be adjusted so that the water instrumentation is on a selected value z-e obtained by hand beforehand the control device eir @; has been set. Your one of the control elements 145, 144; is (from the Ko: .trollvor- direction 150) in each case operated to activate the IZisch, # rirllurk; to. rules, and although it was necessary to speaking of a machining cycle. By setting by hand of the various selected temperatures of the it is possible to use either one of the two heat control elements of these two tomersatures as a working part: il) eratur für ir- according to the selected step of a planar machining beitu: gszy '_- ilus to make available.

It is drained from the system through outlet 123.

The inlet of tube 156 is at such a level above the bottom of tank 155 that normally the level of the tank water will be drawn just below the open tops of the aforementioned nine reagent reservoirs which are designated in FIG. 4 as containers 160a-160i. As shown, these container tops are in turn at a height which is less than the height of the top of the side walls 161 of the tank. When the heated temperature control water is at its normal level in the tank, it is used, as described, to temperature control the reagents that are housed inside the container in the tank. The nine reservoirs 160a-160i are connected by nine corresponding ele '_: trom, - "@ netically actuated bottom valves 165a- 165i to the manifold SO which, as described, leads to the drum chamber 50. These valves are normally closed, but each of one of them can be selected and actuated by an electrical signal from the control device 150 to empty the entire contents of the corresponding container in the manifold and from there into the interior of the drum 55. An additional solenoid operated valve 166 is between the bottom of the tank 155 and the elbow. The valve 166 is normally closed, but is optionally opened by a signal from the control device this water flows downwards through the elbow and through the drum.

A pair of solenoid operated valves 170 and 171 are shown in FIG the discharge lines 106 and 114 for the reagent circulation system. The valves 170 and 171 are normally closed, but they can be activated by a signal from the control device 150 are opened: i'net do this to drain this system.

The drain line for the jacket 121 has a normally closed shut-off valve 172. Since the jacket 121 does not normally have to be emptied, the valve 172 shown is designed as a valve that can be opened by hand. However, it can also be an electromagnetically actuated valve which is optionally opened by a signal from the control device 150. Other parts of the device that are shown in Fi-. 4-4 are shown as being electrically controlled by the control device 150, the pumps 95 and 10, the rotary drum motor 62 reversible by the relay-controlled reversing switch 65, and the fluorescent tubes 130 actuated by the switch 132. The type of treatment of the piece of film in the drum 55 under pro, ramming control is explained with the aid of card 30. One side of the card is shaped to be characterized by twenty-four transversely spaced parallel raised ribs extending longitudinally (ie, in the direction of the liaretn supply). Each of the rural areas covered by one of these ribs is taken is decisive for and corresponds to one of twenty-four channels, each of which has one of the functions in the device according to FiG. 1 steered The long ribs are (through longitudinal Richtui-4r, - in the distance lying transverse guide lines that appear on the map) in 150 dyke zones, each of which has an index step representing the map. Everyone's plastic Rib can optionally (using special cutting tools) to the level of the lower part of the rib in each of the Zones are removed into which the rib is divided. Such an optional removal of the plastic materials in these zones will be individual or all of the grooved channels in the L-direction in the form not removed sections of sips in torn zones brought that with the eliminated sections of the rib (c2.1. spaces) in the other zone parts of the xanal alternate. When the card 30 in the Kontrollvorrichtw-iG 150 each with an index step eii: is led, leads len twenty-four signals before = ications (e.g. spleen switch) the state of the 1? ippe ei: ies corresponding of the twenty-four channels. WeiLZ a given of these Devices feels that the corresponding rib is not is removed, it remains inactive. However, if this pr DIRECTION feels that the plastic c: er rib in the zone removed that correspond to this special index step snLricht, then create,; t sio for the corresponding channel an electrical output divisal through which in the device 1 a valve or another element bet @: ti,; t t.rird, that from. di e: _em channel is controlled.

The card 30 is a recording part to which a almost infinite variety of programs for work cyl: len under:; ubririCen are that of the caution according to Fig. 1 executed we = -den l: bnnen. For example, the Card (in the manner described above) Program that ensures that the device is fully diG automatically uses the known development procedure E-2 and E-3 for ICODAK I # «, 'hTACITOI-I film performed in the Sheet IT 52883 0 8-62 of the Eastman Hodak Company, Rochester, I @ # 'ew York are described. Optionally, the card 30 also a professional ramm for an AI: SCO = intwicl: luigsverfa Iis, en wear. Some methods of using the device according to Fii ;. 1 are described below. It is initially assumed that a Charj; e to be developed from exposed color film. The device is emptied and dried. An empty drum 55 is housed in the drum chamber 50. In preparation for the Entwicklurgsprozeß the upper lid 26 'geöf-net, and the drum 55 is enomrzen herausj-out of its chamber, by simply lifted from the compliant channels 85, 86th While the room in which the device is accommodated is darkened, the Trortimel is filled with the film to be processed by opening this Filra in the Trormlel on the rows of hooks 70 in the manner already described: #ebre .cht is. The drum is then: inserted into its chamber 50, the top lid 26 is closed (to keep any light out of the surroundings of the chamber 50), and normal lighting is then turned back on in the equipment room.

As a further preparatory work for the development process, some or all of the containers 160a-160i are packed with various of the real, enzien to be used in the development process. By using reagents of properly established relative strengths, it can be made that the volume of the reagent in each container can be the same. Likewise, the volume of the reagent in each container is proportional to the area of the film to be processed. Filling each container with the correct volume of reagent is carried out by pouring the reagent into the container until the corresponding liquid indicator 1? indicates (Fig. 1) that the desired volume of reagent is present. To initiate the processing cycle, a plastic card 30. is programmed so that it is first be: .effects that ß the electromagnetically controlled valve 142 (Fig. 4) opens to allow water from inlets 13 and 14 to flow through the system into the Slot 31 of the control device 150 inserted. That Throttle valve 141 is set by hand so that "it the desired volume flow rate of the water per minute allowed. Likewise, the mixing valve 140 is one of a kind previous cycle set so that it is over the Zeitur; 151 lets temperature control water flow out immediately, which in its ordinary temperature of the exact ge the desired temperature. The control members 143 u: ld 144 will go through this for about five minutes initial current heated. Then a previously agreed selected link 143 or 144 through the program on the Card switched on to control the mixing valve so that the outlet water temperature is at the selected value remains, which by previous hanc 'setting of the selected heat control element has been set. After the temperature of the tempering water is below the Influence of the closed control loop with the selected th member 143 or 144 and the signal feedback this Link to the mixing valve driven by a motor til 140 "has been brought, the tempering of the system is by circulating the temperature control water in the tank 155 and through the jacket 121 and over the wall 52, ie the Bottom of the drum chamber 50 continued. One roughly 20 minutes continuous flow of in its temperature regulated water is sufficient to maintain the temperature of the in the Containers housed reagents as well as the temperature temperature of the drum chamber and that of the return line 107 to bring it to the desired value. About 20 minutes after switching on the; selected thermal control anla_`3t d .-. her the program on four hard 30 pressing from b;: isnielweise the bottom valve 165a, so that in the Elbow 80 flows the entire reagent that, in the de- liz *: - filter 160a is housed. This reagent is that first, the one for the programmed development process is before. It flows through elbow 80 and over channel c5 into the floor of Troriaiiel 50. As soon as the entire quantity of the first reagent is in the drum, the bottom valve 165a is closed. sen, and the program card has the effect that the con- Trollvor = direction 150, the motor 62 is energized is to rotate the drum 55 in such a way that the trouriel intermittently reverses its erection.

The distance z:; ischen the discs is from the 4; same dimension as the width of the film to be developed. lie by the coil 180b, these films are 18E on the middle ones Part of the shaft wound between the two Slices extends. Each spool shaft 181 has a simple cylindrical shape End 185 of the same radius as the central part of the wave on; However, each shaft also has an opposite end 186 that is expanded radially to form a bulge. At the thickened end of each shaft there is a cylindrical grommet hole 187 which extends axially into the dent from one end. In addition, the peripheral wall around each such grommet hole is divided into a plurality of resilient fingers 188 by a plurality of equally angularly spaced slots 189 formed in the wall and extending radially through them and axially ^; s of the spout hole extend.

In each coil the grommet hole and elastic fingers are around, this around so that it is with a tight fit the thin end of the shaft another bobbin ve-mag. Therefore, the number of coils can end be coupled together at the end by the thin end of the shaft of each Reels (with the exception of one) into the grommet hole of the shaft of an adjacent one Coil eiii-; e leads, so a firm connection between each two hitched To form coils. When the coils are so connected together they form the elongated cylindrical assembly 190 shown in FIG. 6 supporting the rolls of film carries one or more of the coils.

The roll film on the cylindrical assembly 190 is developed in the apparatus of Fig. 1 by feeding it into a drum 55 '(Fig. 7) with no hooks or pins 72 (Fig. 3) but otherwise with the drum is equal to drum 55. The assembly 190 has an outer diameter smaller than the inner diameter of the drum 55 '. Thus, rotation of the drum during a development cycle causes assembly 190 to roll on the inside surface of the drum and the bottom of the drum so that it gradually and cyclically immerses various angular portions of the roll film in the liquid (reagent or water) at the bottom of the drum. This approach has been found to allow efficient processing of roll films that are too long to be stretched linearly within the drum.
