2 * mounting a lithographic plate on a plate or printing cylinder.

3. Etching of the lithographic plate attached to the plate or printing cylinder with an ink-repellent etching solution sung.

4. Applying the printing ink to the surface of the lithographic plate coated with an etching solution.

After completing the above steps the individual copy sheets are fed for duplication and printing. After duplicating a a certain number of copies, the lithographic plate is removed from the plate or impression cylinder and the outer surface of the blanket cylinder (offset or printing felt or blanket cylinder) is washed.

The individual operations of lithographic offset reproduction n machines that start kneading the paint and end with washing the rubber cylinder Too much manual work and monitoring work so far. On the latest small lithographic duplicating machines all operations of the machine can be controlled by turning a single operating lever will. However, it would be desirable to also do this manual work when moving from a process step to avoid the other.

that for transferring a color image onto copy sheets that has then been transferred from the lithographic plate to the plate cylinder, and with an impression cylinder for pressing the copy sheets against the blanket cylinder.

In the case of the offset reproduction printing machine according to the invention the kneading of the paint starts when a main switch is turned on. Since this procedural stage If a certain period of time is required, the operator sets certain time intervals for etching and coloring and the washing of the blanket cylinder as well as the number of copies to be reproduced while the color is kneaded. These time intervals are set using the appropriate time setting buttons on the outside the duplicating machine are arranged.

After the time interval for kneading the paint has passed, a start button is pressed. A lithographic plate, the previously on a corresponding, in particular trough-shaped feed device provided for this purpose has been arranged, is fed by feeding means and automatically on the plate or impression cylinder attached. At the same time, the etching is started, with an ink-repellent etching solution on the on the plate cylinder attached lithographic plate is applied. As described above, the time interval for application becomes the etching solution previously set by the operator. There are several sentences on the lithographic plate arranged by marks indicating the number of copies to be made. That number is read and put into a Device stored on the machine while the lithographic plate is on the plate cylinder makes one complete revolution.

After the time interval for the etching has elapsed the process "ends and it continues with the application of the Color started. Here, the kneaded ink is applied to the surface of the lithographic print mounted on the plate cylinder Plate applied. After the preselected time interval has elapsed following the beginning of the paint application the feeding of the copy sheets, i.e. the reproduction of the lithographic plate, is started can start.

Each time one of the successively fed copy sheets has been printed, a counter is operated to count the number of copies printed. A command to stop feeding the copy sheets is issued when the number of copies printed equals a number stored in a register. The feeding of the copy sheets and the ink application are stopped. On the other hand, the (hereinafter also called the impression cylinder) on the plate cylinder ejected arranged lithographic plate automatically away, and a ψ therefor provided, in particular trough-like design, cradle. Simultaneously with the removal of the lithographic plate, the washing and cleaning of the blanket cylinder is started. As described above, the time interval for washing and cleaning has also been set beforehand.

When, as described above, the main switch has been turned on, the machine operates at relatively less Speed. However, the machine starts to work at high speed after the depression of the start button the following etching is finished. the

the shaft 31. This rests the element 33 through the spring 34 pulled and counterclockwise by the while 31 pivoted so that the arranged on the element 55 roller 36 causes the first connecting rod 37 in the Swiveled counterclockwise about the shaft 40. From this it follows that a hook-shaped part 43a at the left end of the L-shaped slot 43 is engaged with the pin 47a and that the first locking element 32 is pulled by the spring 35 and pivoted about the shaft 31 in a counterclockwise direction is, so that a bent part 32a at the front end of the first locking element 32 against the upper lateral edge of the first connecting rod 37 is pressed. At this moment, a protrusion on the outer circumference presses the nooke 38, which is integrally connected to the cylinder 16 is, the foIgearm 39 against the action of the spring 42 to the outside (Fig. 4). As a result, the first connecting rod 37 is moved from the position according to FIG. 3 to the position according to FIG moved, with a stepped part 37a on the upper side edge of the first connecting rod 37 with the curved Part 32a of the locking element 32 comes into engagement. As a result, the oscillating nook 47 moves together with the short arm 44 counterclockwise into an operating position, namely due to the hook-shaped part 43a and against the action of the spring 104. The nooke 47 is held in this operating position during a duplication cycle by the magnetic coil 26, which as long as works until a certain duplication cycle is over.

The engagement between the first connecting rod 37 and the first locking element 32 is released when the main switch is turned off and when the solenoid 26 on Becomes ineffective at the end of the reproduction cycle. As soon

the solenoid 26 is ineffective, the role of the follower arm 39 runs on the projection 38a of the cam 38, so that a cutout 37a of the first connecting rod 32 disengaged from the bent portion 32a at the front end of the first locking element 32 is brought «The oscillating Nooke 47 pushes the roller 50 to the outside, whereby the follower arm 48 with the shaft 49 iai clockwise against the action the spring 51 is rotated. As a result, the nook 81 connected to the shaft 49 rotates clockwise out of a Position according to FIG. 7. This has the consequence that the roller 88 with a stepped part 81a of the crouch 81 in engagement comes and that the roller 87 with a stepped part 81b of the nook 81 comes into engagement. Therefore the arms become 85 and 86 slightly rotated counterclockwise and clockwise, respectively. This causes the bearing 96 of the ink roller to slide 94 and the bearing 98 of the other ink roller 95 a small distance from the fixed cams 97 and 99j so that the rollers 94 and 95 both against the Press on roller 91.

When the oscillating nooke 47 turns counterclockwise from a position 'according to FIG. 3 into a position 4 rotated, the Noeke 80 attached to the shaft 46 of the Nooke 47 rotates counterclockwise, so that the nook 80 moves the roller 84 downwards and the arm 83 rotates counterclockwise around the shaft 89 turns. This presses the roller 82 against the rollers 90 and 91 from which it is normally separated is. A bearing 108 of the roller 82 is, normally pressed down by a spring 107 »Since the upper end

009827 / U07

de the connecting rod 74 with the short arm 44 through the first connecting rod 37 is pulled moves the connecting rod 74 downwards. The moving together with the connecting rod 74 in the corresponding manner Pin 73 rotates about shaft 76 an amount equal to the downward movement of connecting rod 74 is equivalent to. As a result, arm 77, which is integrally connected to arm 72, is rotated counterclockwise around shaft 76 rotated, whereby the pin 78 connected to the arm 77 is released from engagement with the arm 102a of the rod 102 (Pig. 7). The rod 102 thus rotates clockwise about the shaft 103, causing the roller 101 against the roller is pressed.

Since the first connecting rod 37 moves to the left from a position according to Pig. 3 in a position according to Pig. 4 are moved all rollers and rollers that come into embossing when kneading printing inks, and according to Pig. 8 arranged at a distance from each other are brought to bear against each other (see Fig. 9), so that the ink can be kneaded. At this point the rollers 94 and 95 are spaced from the impression cylinder arranged.

When pressing the start button after finishing the printing ink kneading a lithographic plate or pattern is automatically placed on the impression cylinder. At the same time the etching is started. As already mentioned, the length of time for the etching is set beforehand by the operator set so that the solenoid 67 is automatically energized once the etching is finished, if a certain Time has passed.

The roller 66 of the connecting element 64 causes the connecting rod 53 to be rotated about the shaft 57 in a clockwise direction. Here, the hook-shaped pin 54a is brought into singular engagement with the pin 52. On the other hand, the second locking element 62 is rotated generally clockwise around the shaft 65 by the pin 71, with the curved part 62a at its front end is pressed against the lower edge of the second connecting rod 53. When the holster 59 is pushed outward by the crouch 38 and the lever 56 rotates clockwise, the second connecting rod 53 is pulled to the left, with the bent portion 62a of the second locking element 62 in engagement with a cutout 53a formed in the the lower edge of the second connecting rod 53 is arranged.

i The second connecting rod 53 is disengaged from brought to the second blocking element 62 when the solenoid 67 becomes ineffective at the end of the reproduction cycle, to trigger a command to apply paint. As soon as the Solenoid becomes ineffective, it runs on the Polgeele « element 58 fixed roller on the projection 38a of the nooke 38, causing the bent portion 62a of the front end of the second locking member 62 to disengage from the cut 53a of the second connecting rod 53 is brought. Once the connecting rod 53 has been moved to the left is (see Fig. 3), the one with the hook-shaped part 54a

engaged pin 52 drawn through rod 53. This results in a clockwise rotation of the Follower element 48, from a position according to Pig. 4th into one according to Pig. 6. Due to the rotary movement of the follower element 48, the attached element rotates Wave 49 at the same time, whereby the Nooke 31 (see Fig. 7), the is connected to the shaft 49, is also rotated clockwise. This creates roles 88 and 87, which are respectively received by the stepped parts 81a and 81b, out of engagement with the respective stepped parts Split so that the ink rollers 94 and 95 support Arms 85 and 86 are rotated counterclockwise and clockwise, respectively. The ink rollers 94 and 95 are thus brought into engagement with the impression cylinder 15, both of which are in engagement with the platen 91 stand so that the color is on an already etched and lithographic plate placed on the impression cylinder can be applied.

The second connecting rod only leads one back and forth outgoing movement after the end of the etching until the magnetic coil 67 is again excited.

Before the ink is applied to the lithographic plate on the printing cylinder after the ink kneading has been completed will have to automatically carry out the processes of application and mounting the lithographic plate, reading the number of hard copies and the etching can be performed. An instruction to feed a lithographic Plate from the trough-like feeder provided for this purpose and a command to start etching at the same time to a magnetic coil 110 according to FIG. 11

When the magnet coil 110, which is arranged on the left side plate 1, is energized in accordance with these commands, is with started the following operations: mounting a lithographic plate on the printing cylinder, reading the number of to duplicating copies, applying an etching solution to the lithographic plate on the printing cylinder.

On the left side of the solenoid is a bumper 112 | provided with a roller 111 facing to the left the solenoid 111 shifts when a movable Rod 115 of the solenoid to the left when the solenoid is energized is moved. On the left side plate 1 there are two pins 114 and 115 which are offset from one another at an angle attached, which carry a first slide member 116 and a second slide member 117, respectively. The two sliding elements are approximately the same width and can slide a distance equal to the larger dimension of two slots 1i6a and 117a corresponds. The second slide member 117 is rotatable connected at one end to the front end of an arm mounted on a shaft 118, while the other End with the central part of an engaging arm 120 '

is bound. The engagement arm 120 is rotatably mounted on a shaft 121 supported by the side plate 1 and is provided with a free end which has a stepped part 120a, which is with a square Pin 123 is in engagement with a gear segment 122 is connected and lies to the outside. The gear segment 122 is rotatably arranged on a shaft 124 · which lies within the left side panel. The square pin 122 extends outwardly through one in the side plate 1 curved opening 125 formed.

segment is pulled upward by wire 127, one end connected to the shoulder of the gear and the the other end is connected to the end of a compression spring with a relatively high spring force. The compression spring is with the the other end connected to the side plate 1. The square pin 123 thus presses firmly against the remote one Part 120a of the engaging part 120.

A pin 129 is connected to the upper end of the first slide member 116 and extends through the slot in the second sliding part 117 extends outward. Between the Pin 129 and a shaft 130 a compression spring 131 is arranged, which pushes the first slide 116 obliquely upwards and to the left with respect to the second slide 117, The second slide 117 is slanted upward and to the left with respect to the side plate 1 by a compression spring 133, which is arranged between the pin 115 and a shaft 132. One on the inner surface The pin 154 attached to the first sliding part 116 is loosely arranged in a slot of a lever 136 which is rotatable is arranged on a shaft 135 supported by the side plate. The lower edge of the front end of a The arm of the lever 136, which extends to the right, is engaged with the upper part of the roller 111. A locking arm 410 is rotatably mounted with its base on the pin 115 and with a projection 410a at its free end located at the end of the path of movement of the square pin 123.

The shaft 118 on which the arm 119 is mounted is rotatable with its two opposite ends through the left and right side plates of the machine supported,

⁴⁴⁴⁹ 0098.27 / U07 ^ or, g, _N al

as shown in FIG. Within the right Side plate is on the end that the brew? On which the Arm 119 is attached, opposite, an engaging arm 137 is attached, which with a bent part 139 a of a Locking piece 139 is in engagement, which is attached to an internally toothed gear segment 138, which is rotatable on a shaft 140 connected to the inner surface of the right side plate of the machine is. The gear segment 138 is normally through a Spring 141 rotated counterclockwise around shaft 140 with a relatively high spring force. This movement is going through the locking piece 139 and the engaging arm 137, which is engaged therewith, controlled or limited.

A gear 144 meshes with the gear segment 122, which is loosely arranged on a shaft 143 which supports a roller 142. The gear 144 is with of the shaft 143 by means of a coupling 145 which transmits rotation only in one direction. The gear 144 is rotated back and forth clockwise and counterclockwise by the gear segment 122. The clutch 145 transmits the rotation of the gear 144 to the shaft 143 only when the gear 144 is clockwise turns. A counterclockwise rotation is therefore not transmitted. A relatively short arm 146, the is supported at its lower end by a shaft 126 connected to the shoulder of the gear segment 122, is provided at its upper end with an opening which loosely receives a shaft 108, which by means of a nut and a screw is fixed in a suitable place in the edge of a slot 149 which is at the front end an arm 148 connected to a gear 147

Q09827 / U07

see is. The point where the shaft 108 is attached, can be adjusted so that the rotation angle of a feed roller 151 for the lithographic plates changes can be. A shaft 150 holding the gear 147 is with one end mounted in a double plate, which is attached to the inside of the left side plate of the reproduction device, side by side with the left side, plate, is arranged. The other end supports one end of a shaft 409 'which is connected to its other end by a Double plates are supported on the right side (and side by side with the reproduction facility is arranged. A pair of vibrating plates 152 which rotatably support a roller 151 for feeding lithographic Hold plates are loosely arranged on the shaft 409. The roller 151 is connected to the gear 147 via a gear 154 connected that is loosely arranged on a shaft 153 which holds the roller 151 and an intermediate gear 155. As Fig. 17 shows the shaft 153 with the gear connected to a coupling 156 which is effective only in one direction and which controls the rotation of the gear 154 on the shaft 153 only transmits when the gear 154 rotates in the direction of the arrow.

With the internally toothed gear segment 138 (θ.Pig.22), the actuates the etching device, a gear 157 is in engagement, which is arranged on a sleeve-shaped shaft 158 which loosely surrounds a shaft 159 supported by the side plates of the duplicator. A Arm 160 with a pin 160a, which is attached to the front end, is with the inner end of the sleeve-shaped Shaft 158 connected. A sprocket wheel 161 through which the sleeve-shaped shaft 158 is loosely passed

with an immovable part of the reproduction equipment, e.g. with the side plate or a double plate. An arm 162 is connected to the shaft 159, which rests against the pin 160a. The arm 162 holds along with it its front end rotatably a shaft 164, which supports a sprocket 163 with its outer end. The solid Sprocket 161 and the rotatable sprocket 163 are connected to each other by an endless chain 165. With the inner end of the poly 164 is an applicator 166 connected for an ink-repellent etching solution, which has a hexagonal cross section and a Has width slightly greater than the width of the lithographic plate or pattern. The lithographic plate consists of a material which is adapted to the etching solution, so that the desired one by immersion in the same Effect is obtained. With the outer end of the shaft 159 'which is outside the right side plate of the Extending duplicating device is an engaging member 167, which has a curved end 167a that can be locked by a locking arm 168 (3Pig.22), which rotates on a shaft 169 on the outside of the {

right side plate is arranged. The shaft 169 rotatably carries an element 170 with its lower end a movable rod 172 of a solenoid 171 a connecting rod 173 is connected. A pin 174-, which is connected to the arm 170 is connected to the locking pin 168 by a compression spring 175.

A roller 176 which pairs with the feed roller 172 (Pig.24), is supported by two oscillating parts 178 and 179 which are supported by a shaft 177, welohe connected at one end to the side plate of the machine

is. The parts 178 and 179 are provided with rollers 180 and 181, respectively, at their lower ends. The roller 180 rests against the upper edge of a relatively short arm 182. The roller 181 rests against the upper edge of an arm 183 which is longer than the arm 182. The arm 182 is fixedly connected to one end of a shaft 184 which is rotatably supported by the side plate of the duplicator. The arm 183 is fixedly connected to the other end of the shaft 184. A follower arm 185 connected to one end of the shaft carries at its free end a roller 186 which is pressed by the force of a spring (not shown) against the circumferential surface of a nook 187 which is integrally connected to the pressure cylinder 15. As can be seen from FIG. 15, another nooke 188 connected in one piece to the printing cylinder is arranged above the nooke 187. A roller 189 rotatably arranged at the distal end of the gear segment 122 presses against the nooke 188. A nooke 190, shown in FIGS 24 and 28, an upright rod 192 ″ is connected at its lower end to the front end of the arm 183. In the vicinity of the upright rod, a locking element 193 is arranged, which is provided at its lower end with a hook 193a, during the upper part is connected to a spring wire 194. The other end of the wire 194 is in the form of a loop 194a which surrounds a pin 196. The upper part of the locking element 193 is arranged on a shaft 195 which is supported by the side plate of the machine The pin 196 is connected to one end of the internally toothed gearwheel segment 138.

"009827 / U07

Like Pig. 15 to 17 see below, there is an elongated ossf Nooke 197 rotatable in the area of your Baaisendee supported by a shaft 19P that is immovable in a Part is stored. Me Nooke 197 is pressed by a spring 308 with its front end against a pin 200, the is connected to an arm 199 which is integrally connected to the gear segment 122.

On one end face of the printing cylinder, an arm 202 for opening and closing gripping claws is arranged, which is attached to a End carries a scroll 201, as shown in Pig. 18 is shown. A shaft 203, which with its outer end with is connected to the arm 202 is rotatably supported in opposite end plates of the printing cylinder 15. Claws 204 are connected to the shaft 203. The arm 202 is normally by the force of a compression spring 205, which is arranged between the pressure cylinder 15 and the arm 202, in the clockwise direction - with respect to the pressure cylinder - pressed. The gripping claws 204 therefore push against a flat surface 15b between a relatively large cutout 15a in the printing cylinder 15 and a peripheral surface of the printing cylinder, as shown in FIG.

Another shaft 206 parallel to the shaft 203 is also rotatably supported by the pressure cylinder 15. With the wave 206 claws 207 are connected. The outer end of the shaft 206 extends through the outer end surface of the impression cylinder 15 and is provided with a fork-shaped part 208 attached thereto. A roll of 209 running on a Arm of the fork-shaped part 208 is attached, is pressed by the force of a spring 211 against a cam 210,

009827 / U07

the one on the inside of the right side panel of the duplicator "is attached. Me spring 211 is one end connected to the end of an arm of the fork-shaped part 208 connected and at the other end with a part of the printing cylinder. The front end parts of the claws 207 are bent inwards (see Figs. 20 and 21), with front End portions 207a of the pawls normally in a recess above the flat surface 15b of the printing cylinder lie.

If the start button is pressed after the ink has been kneaded, the magnetic coil 110 (see Fig. Ii) operated, the bumper 112 to the left against the Effect of the spring, not shown, is shifted. The roller 111 attached to the bumper 112 causes the lever 136 rotates counterclockwise around the shaft 135 turns. The first sliding element 116 can thus move downwards and move diagonally to the right against the action of the spring. The first slide member 116 is flat with a Cutout 116b is provided on one side of the lower part. When the sliding member 116 is as described above moved, a curved part 410b of the locking arm 410 comes into engagement with the cutout 116b (see Fig. 12), so that the return movement of the sliding member 116 is prevented. The aforementioned movement of the first sliding element

116 "loads" the spring 131 so that the second sliding element

117 is pulled by the spring 131 for movement in the direction of the first slide member. The movement of the second sliding element is prevented by the square pin 123, which presses strongly against the recessed part 120a of the engaging arm 120. The movement of the second sliding element is not only caused by the engagement of the qua-

009827 / U07

BATH ORIGINAL

1985227

dratic pin 123 with the engagement arm 120, but also prevented by the engagement of the engagement arm 137 with the locking piece 139. The engagement arm 137 is with the the other end of the shaft 118 connected to the arm 119 to an end. The movement of the second sliding element 117, which is caused by the force of the spring 131, is thus prevented as long as the bent part 139a of the locking piece 139 presses strongly against the engagement arm 137. .

When the pressure cylinder 15 rotates, so that the Nooke pushes the hollow 189 outward (Fig.15), while the spring 131 remains "loaded", the gear segment 122 shifts a little clockwise about the shaft 134, with the force with which the square pin 123 is engaged with the engaging arm 120 is weakened. If, due to further rotation of the printing cylinder 15, the nook 190, the roller 191 of the internally toothed gear segment 138 pushes outwards (Fig. 16), the internally toothed gear segment 138 moves a little clockwise around the shaft HO, whereby the force with which the engaging arm 137 engages with the locking piece 139, is reduced. The reduction in the force with which the engagement arm 137 is in engagement with the locking piece 139, takes place during the time during which the force with which the square pin 123 is connected to the gear segment 122 is engaged, is reduced or the roller 189 is pressed outward by the nooke 188.

The forces of restraint and restraint on the second Acting sliding element 117, all cease to exist if the force with which the locking piece 139 of the internally

^ 009827 / U07

toothed gear segment 138 with the engagement arm 137 in Engagement is, is reduced and that following the reduction in the force with which the square pin 123 with .dem Engaging arm 120 is engaged. The second sliding element 117 is thus quickly downwards and obliquely shifted to the right by the force of the spring 131. Here ~ the engaging arm 120 rotates counterclockwise around the shaft 121 (see the dashed lines in Pig. 17) » so that the engagement arm disengages from the square pin 123. If the Nooke 188 is subsequently further rotates counterclockwise with the pressure cylinder so that the roller 189 against the smaller diameter part 188a of the Nooke 188 is applied, the gear segment 122 is pulled by the wire 127 upwards. When the gear segment 122 is in this position, it will cause gear 14-4- to rotate. However, the rotation of the gear 144 will not transmitted through the coupling 145 to the shaft 143, i.e. the roller 142 remains at rest. on the other hand the gear 147 connected to the gear segment 122 is moved in the direction of the arrow by the arm 146 - this presses that Gear 147 up - rotated so that gear 154 is rotated in the direction of the arrow. This rotates the Shaft 153 in the same direction as it is connected to gear 154 via clutch 156. Thus it becomes a lithographic Plate or pattern - 19a conveyed by the feed roller 151 and the edge at the front End is gripped by feed rollers 176 and 142 When the roller 189 is pushed outward by the cam 188 is rotated while the disk 19a is in this position the gear segment 122 clockwise around the shaft 124 against the tensile force of the wire 127. The rotation of the Gear segment 122 is on gears 144 and 147

009B27 / U07

transfer. The rotation of the gear 147 is not carried out transmit the clutch to the feed roller 151. The rotation of the other fence wheel 144 is applied to the feed roller transfer. The pattern 19a thus becomes the printing cylinder fed by feed rollers 142 and 146.

Pig 18 shows the front end edge of the pattern 19a 'as it is being inserted into the gripping claws 204 and after i WOR shifted to the left by the rollers 142 and 176 is the. When the gear segment 122 rotates counterclockwise as shown in FIG. 17, the pin 200 connected to the arm 199 pushes the oscillating cam 197 downward. This engages a front end 197a of the cam 197 with a cutout 212a in the locking member 212. The locking member 212 is rotatably supported by a shaft 213 connected to the inside of the left side panel of the duplicator and counterclockwise by an unillustrated spring is pressed. This prevents the oscillating cam 197, which is in engagement with the notch 212a, from returning to its original position.

Since the oscillating cam 197 is pushed down, its lower side edge comes within the movement path of the roller 201 of the claw opening and closing Part 202 to lie. Since the roller 201 of the part 202 that rotates together with the printing cylinder 15, the lower side passes the oscillating cam 197, the roller 201 is driven by the lower side edge of the oscillating cam 197 pressed so that the opening and closing part 202 rotates counterclockwise. The the Part 202 carrying shaft moves counterclockwise,

009827 / U07

so that the claws 204- open.

Another rotation of the pressure cylinder 15 in the G-e-clockwise direction from the position according to "Fig. 18-brings the roller 201 out of engagement with the oscillating Nooke 197, so that the claws 204 are closed and hold the leading end edge of the pattern 19a against the impression cylinder. if the gripping claws 204 are in the open position, "the pushing claws 207 remain closed. If accordingly the pattern is gripped by the gripping claws 204, the front ends 207a of the pushing claws 207 are below the pattern 19a arranged (see Fig. 20).

If the printing cylinder does not grasp a pattern 19a and thus without a pattern rotates into a position according to FIG. 19, the roller 209 of the fork-shaped part 208 comes with the Part 210a of the smaller diameter of the fixed nooke 210 engaged. This results in a counterclockwise rotation of the fork-shaped part 208. Due to the rotation of the fork-shaped part 208, the end 208a of the other stands Arm outwards, as a result of which a pin 215 fastened to the front end of an arm 214 (Fig. 19) butted and the front end of a curved arm 216 is displaced. As a result, an actuation se lerient 218 of a switch 217 is set in an oscillating motion, whereby the switch 217 is actuated. The switch 217 indicates that the automatic operation of the printing cylinder is not flawless. It is also possible to prevent the next step from being carried out.

When the pattern or lithographic plate is through the Printing cylinder is gripped, the front ends are

009827 / U07

207a under the underside of the pattern and are held in place by the pattern so that the roller 209 is against it is prevented from coming into engagement with the smaller diameter part 210a of the nooke 210 (in contrast to the Xage of the role 209 according to Pig. 19). As a result, the end 208a of the other arm of the fork-shaped part 208 can extend lengthways a path separate from the pin 215 without the switch 217 being actuated.

When the pattern gripping operation is performed as described above, the internally toothed gear segment 138 is actuated by the nooke 190, which has a slightly varying actuation radius. Pig. 22 shows the Nooke 190, which is integrally connected to the printing cylinder 15, in a position in which it is calibrated in a counterclockwise direction from the position according to Pig. 16 has turned. The roller 1-91 is pressed against the part with the smaller diameter of the Nooke 190. In this position of the Nooke 190, the internally toothed gear segment is rotated counterclockwise around the axis and shaft 140. When the internally toothed gear segment 138 rotates counterclockwise, following the rotation of the Nooke in said direction, the gear 157 meshing with the gear 138 rotates counterclockwise and the pin 160a, which is connected to the front end of the arm 160 - this is integrally connected to gear 157 - is connected, rotates support arm 162 in the same direction. As a result, the application device 166 for the etching solution is moved from the position 166A to the position 166B and pressed against the pattern. Positions 166A and 166B are indicated by dash-dotted lines in Pig. 22 shown. When the support arm 162 moves, the chain rotates

Q.Q9827 / UO7

tenrad 163 on the axis 164 in Pfeilriohtung, so that the applicator 166 moves from 166A to 166B without rotation - about its axis - with respect to one fixed part. This creates the underside 166a of the applicator 166 engages the surface of the pattern when in position 166A. the Applicator 166 is immersed in a suitable etching solution in the same position as in position 166A.

The shaft 159 ', which is set in rotation by the internally toothed gear segment 138 via the gear 157 and the pin 160a integrally connected therewith, is rotated clockwise and returned to its original position by the engagement of the bent part 167a of the engaging part 167 prevented from moving as a unit together with the shaft 159 with the front end portion of the locking arm 168 as shown in FIG. This prevents the part 166 from returning to its original position. Since internally toothed gear segment 138 rotates clockwise about shaft 140 while nooke 190 rotates counterclockwise, gear 157 and arm 160 are returned to their original positions while applicator 166 remains in position 166B.

The period in which the applicator 166 is held in engagement with the pattern or the etching is carried out is set in advance so that the solenoid is energized and the arm rotates about the shaft 169 in the clockwise direction at the lapse of this time. As a result, the pin 174 of the arm 170 is pressed against the rear edge of the locking arm 168 and the arm 168 is rotated about the shaft 169. This makes the engagement steep 167

009827 / U07

BAD ORiGiNAL

out of engagement with the locking arm 168. When sieve the We13 β 159 rotates freely, the application device 166 from the Operating position 166B returned to the position 166A in which it is ineffective. This is done through the Effect of a return spring, not shown,

If so, the gear segment 122 to operate the feeder for the pattern around the shaft 124- his in its final position is moved, the square pin 123 comes from below to the plant with the projection 410a of the locking arm 410. This rotates the arm 410 about the shaft 115. The curved part 410b (see Fig. 12), which is connected to the Cutout 116b of the sliding part 116 is in engagement, is thus disengaged. The first sliding element 116 acts as a unit with the second sliding element 117, the has already been pulled by the spring 151. The sliding elements 116 and 117 are thus shifted upwards and obliquely to the left by the spring 135. The arm 119 rotates counterclockwise to return to its original position. This makes the engaging arm 137 connected to the shaft 118 of the shaft 119 is connected, returned to its original position, where it prevents the movement of the locking piece 139 of the internally toothed gear segment 138 prevents actuation of the gear 138 is prevented. The solenoid 110 is designed to be actuated immediately when the command to feed a pattern is given. It also becomes ineffective immediately afterwards the lever 136 rotates.

As mentioned above, the pin 196 of the internally toothed gear segment 138 moves the free end of the spring wire 194 upwards (see Fig. 26) when the tooth

009827 / U07

wheel 138 rotates counterclockwise. As a result, the locking element 193 is rotated clockwise about the shaft 195. When the internally toothed gear segment 138 is in the position shown in FIG. 25 - before it moves - the roller 186 is held in engagement with the larger diameter portion of the nook 187 and the arm 183 has moved counterclockwise, the upright and upright rod 192 with its upper end against part of the oscillating plates 152 or the shaft of the intermediate gear is in contact. The oscillating plates 152 thus rotate counterclockwise about the shaft 4-09, thereby keeping the feed roller 151 out of engagement with the patterns and plates 19. When the roller 186 comes into engagement with the smaller diameter portion of the crouch 187 - with the locking element 193 held away from the upright bar 192 as shown in FIG upright rod 192 is moved downwards. This engages the pattern feed roller 151 with the patterns 19. The gear segment 122 starts rotating immediately after the pattern 19 feed roller 151 is pressed against the pattern 19.

Even if the roller 186 comes into contact with the smaller diameter part of the nooke 187, if the internally toothed one Gear segment 138 engages with the engaging arm 137 as shown in FIG. 28, the upright bar 192 becomes prevented from moving downward by the bent portion 192a which engages the hook 193a stands. The feed roller 15I thus becomes in the upper tier held. The feed roller 151 is thus brought into engagement with the patterns and plates only when the magnetic

009827 / U07 BADORiGlNAL

coil 110 (see Fig. 11) "is actuated.

The locking element 193 comes out of engagement with the upright Rod 192, when internally toothed gear segment 138 rotates a certain amount counterclockwise, while the hook 193a and the bent portion 192a are engaged with each other by a strong force as shown in FIG being held. The locking piece 139 is disengaged here with the engaging arm 137. Then the roll 186 g through the larger diameter portion of the nooke 187 is outward so that the upright bar 192 moves a little upwards, which increases the force with which the bent Part 192a presses against the hook 193a, is reduced. Even if the internally toothed gear segment 138 rotates, the spring force of the spring wire 194 is too small to engage the bent portion 192a with the Loosen hook 193a when these two parts are engaged with each other with a strong force. Fig. 27 shows the engaging part 193 disengaged from the bent one Part 192a due to the spring force of the wire 194 when the roller 186 through the larger diameter part of the nooke 187 is pushed outwards after the internally toothed ^ gear segment 138 has rotated a certain distance Has.

The upper roller 176, which is attached to the impression cylinder by the Roller 151 feeds plates (a.Pig.24), is supported by the oscillating members 178 and 179 and engages lower roller 142 when arms 182 and 183 have rotated clockwise

When the application of the ink is finished, a command to Given feeding of copy sheets, wherein a solenoid, not shown, is energized, which is a feeder for the aforementioned leaves in motion.

On the basis of a corresponding command, the copy sheets 20 are successively fed to the impression cylinder 17. Each sheet is with its front end edge between the gripping claws 227 in the open state (Fig. 40) and the plane Surface 403a (Fig. 33) of the impression cylinder used. At the same time, the impression cylinder 17 is rotated counterclockwise and the roller 221 of the follower plate 219 is brought into engagement with the smaller diameter portion 222a of the nooke 222. The gripping claws 227 are closed and grab the leading edge of the sheet in question (Fig. 41). When the impression cylinder 17 is counterclockwise is further rotated at this stage and the roller 221 in engagement with the projection 222b of the nooke is brought, the pawls 227 open and release the sheet. At the same time, the role 231 of the slave arm comes from engagement with the larger diameter portion 232a of FIG Cam 232 free and comes into engagement with the smaller diameter portion 232b, so that the front end of the released The sheet is pushed by the ejection claws 234 and removed from the impression cylinder.

A color image on the rubber or pressure fuselage cylinder 16 is transferred to the sheet clamped by the claws 227 when this between the cylinder 16 and the impression cylinder is passed through.

The roller 231 for operating the ejecting claws 234 passes another smaller diameter part 232c before it comes into engagement with the smaller diameter part 232b. When the sheet clamped by the claws 227 is properly positioned, the ejecting claws 234 are checked through the underside of the leading end portion of the sheet, thereby preventing the roller 231 from engaging with the smaller diameter portion 232c . However, if the sheet is not properly gripped by the claws 227, the movement of the ejection claws 234 is not checked or inhibited, so that the roller 231 comes into engagement with the smaller diameter portion 232c as shown in FIG. With the end of the shaft 229 opposite to the end at which the follower arm 232 is attached to the roller 231, an actuating arm 307 is connected, which can be rotated outside of the impression cylinder according to FIG. 42 when the roller 231 is in engagement with the smaller diameter part 232c comes or if the sheet is not properly arranged at the intended location on the size printing cylinder. The pin 251 of the inner army 252 is thus pushed outward. When the pin is pushed 251 to the outside, the arm integrally connected to the inner arm 252 249T of the machine is arranged on the outer side of the side plate, rotated clockwise 35 according to Fig., Such that the connected to the arm 249 _hooked% Lever 247 is also rotated in the same direction by spring 250.

The clockwise rotation of the drive plate 240 results in a Drehnng - in the same direction - of the follower plate 239, the eccentric WeIIe ₉ s of the follower plate 239 is fixed due to the action of the spring 243 ", check rotates thus at the same time, and therefore the shaft 238 in a clockwise rotation t and the impression cylinder 17 is brought into engagement with the cylinder 16. The sheet is guided back and forth between these two engaged cylinders.

When the sheet is not properly gripped by the claws 227, the bent portion 240b becomes the drive plate 240 is not held by the hook 247a, since the hook-shaped lever 247 has already been pulled by the arm 249 iat and has already turned clockwise. The drive plate 240 moves back and forth in a reciprocating pivoting movement due to the Yorprunges 309a on the nooke 309, since the pin 251 by a front end edge 307a of the actuating arm 307 according to Fig. 42 is printed outward.

The force with which the impression cylinder is brought into engagement with the cylinder 16 can be a function of the amount of rotation of the while 258 with respect to the eccentric Shaft 238a can be changed. A crouch 310 for Adjusting the pressure force is arranged on the side plate of the machine and is used to adjust the angle of the Clockwise rotation of slave arm 239 which is connected to shaft 238. The amount of rotation of the crouch 310 can be set from outside the duplicating machine. With the roller 245 resting against the edge the Nooke 310 is brought, it is possible to determine the extent of the rotary movement of the slave arm 239 or the extent of the force, with which the impression cylinder is urged into engagement with the cylinder 16, depending on the type of used Set copy sheets.

Since, as shown in FIG. 35, a connected to the outside of the cam 309 Nooke 311 turns clockwise with the cylinder 16 rotates, a protrusion 311a of the cam 311 pushes a roller 312 of the slave arm 258 slightly so that the force varies with which the follower arm 258 is held in engagement with the hook-shaped part 253 is reduced. The slave arm 258 does not come out of engagement with the hook-shaped part 253 at this point in time, since the latter is pulled by the spring 257 the follower 258 rotates a little each time the projection 311a on the cam 311 against the roller 312 abuts. When the drive plate 240 shifts into the position according to FIG. 36, its lateral edge 24Oc hits an arm which is connected to the short arm 254 Pin 313 so that the short arm rotates around shaft 255. The spring 256 is thus "charged" so that the hook-shaped Part 253 for a clockwise rotation around the

The fol gearm 25Ö is then against the. Action of the spring 270 rotated counterclockwise about the shaft 259 when the projection 311 the roller 312 happens. The light shielding plate 263 is therefore down from a position in which it aligned with the light receiving aperture 264, "moved, whereby a light receiving element such as cadmium sulfide or a photoelectric one cell, is operated. This is arranged behind the opening 264 for generating pulses.

The slave arm 258 can only be rotated and swiveled, when the drive plate 240 is held in engagement with the hook-shaped lever 247 or when the sheet is properly is gripped by the claws 227 on the impression cylinder. While the drive plate 240 with the hook-shaped When the lever is engaged, the follower arm 258 moves back and forth in the course of a reciprocating motion Pivoting movement, as the Nooke 311 makes one complete revolution and one pulse for each back and forth ' walking rotary motion generated. The number of pulses generated in this way corresponds to the number of copies printed.

Since the illegal shield plate 263 executes a pivoting movement, the plate 290 associated with it by the connecting rod 265, the arms 267 and 274, the connecting arm 276, the arm 280, the fork-shaped arm 282 and the lever 404 causes a vibrating movement relative to one another

On the other hand, the tubular rod 293 performs a reciprocating axial movement due to the rocker arm 295 and the arm 294 in connection with the plate 290 aue, so that the movable side plate 24 substantially integrally connected to the tubular rod 293 performs a vibratory movement and against abuts the side edge of the printed copy sheets, which are successively guided onto the receiving table provided for this purpose, so that the side edges of all the printed copy sheets on the receiving device provided for this purpose are aligned with one another. A wire 315 according to Pig. 44 is loosely supported at one end by a shaft 316 which is connected to part of the reproduction equipment. The free end of the wire 315 is located in an open-topped elongated groove 318 which is located in a stopper 317 for the printed copy sheets. The wire 315 serves to hold the printed copy sheets slightly downward on the receiving table provided for this purpose.

If the number of pulses generated is equal to the predetermined and preselected number of copies to be printed, a command is given from a coincidence circuit to a printing end signal generator, so that a solenoid coil, not shown, is ineffective for so long

On the other hand, the coil 26 (see FIG. 4), which keeps the device in motion to _{apply the paint, is also rendered ineffective 9} so that the application of the paint is terminated and the printing ink whales 94 and 95 are disengaged from the Pressure cylinder come.

At the end of the application of the printing ink, a magnetic coil 319 (see FIGS. 3? Ig.5i) is excited ₉ so that an oscillating plate 340 is moved downwards by a movable plate 341. The excitation of the magnetic coil 319 sets a device in motion which serves to automatically remove a lithographic plate or a pattern from the printing cylinder and introduces the same into the receiving device provided for this purpose, which is designed in the form of a trough.

The oscillating plate 340 is rotatably supported by a shaft 342 which is attached to the side wall of the duplicator. An engaging arm 343, which is connected to the oscillating plate by a compression spring 344, is also rotatably supported within the oscillating plate 340 by the shaft 342. The upper side edge of an oscillating arm 346 is urged by the force of a spring 347 against a pin 345 which is attached to an elbow-shaped part of the oscillating plate 340. The oscillating arm 346 is connected to the outer end of a shaft 348 which is rotatably supported by opposing side plates. Scraper claws 349 with sharp front ends 349a, which are arranged in the immediate vicinity of the outer periphery of the printing cylinder 15, are connected to the base with the shaft 348.

A locking element 407, which can cooperate with the engagement arm 343, is with the outer end of a shaft 350 which is rotatably connected to the side wall 1. A contact element 351 is at its upper end with the inner end of the shaft 350 connected. A connecting rod 353 is rotatably supported at one end by a shaft 352 connected to the oscillating plate 340 is. At the other end there is a slot 354 which loosely receives a pin 355 which is associated with the locking element connected is. A compression spring 356 is arranged between the pin 355 and the connecting rod 353 ..

A feed roller 357 for the samples is in close proximity Arranged near the outer peripheral surface of the printing cylinder 315 and rotatably supported by the free end of a shaft 380 which is loosely attached to its base by a transverse shaft which is connected to the side panel of the duplicating device. With the outer end of the Cross shaft is connected to a short arm 359 which carries a pin 360 which is connected to the locking element 407 by a pressure fc spring 361 is connected. The pen 360 is normally pressed against the side edge of the locking element.

When, upon completion of the application of the ink, the solenoid 319 according to Pig. 52 is energized, the oscillating plate 340 is pivoted counterclockwise about the shaft 342 against the action of the force 362. The oscillating plate 340 sees the locking element 407, which is connected to the connecting rod 353 by the spring 356, so that the element 407 also rotates about the shaft 350 in the counterclockwise direction. As a result, the engagement arm 343 comes into engagement with the blocking element 407.

On the other hand, the short arm 359 becomes through the Force of the spring 361 (see Fig. 42) pulled when the locking element 407 rotates counterclockwise »so that the one piece with the short arm 359 connected arm 358 pivots clockwise, whereby the roller 457 against the pressure cylinder 15 is pressed. At the same time, the contact element 351 also rotates together in a clockwise direction with the locking element 407 so that the side edge 351a lies within the path of movement of the roller 201 come like this Pig. 52 see below.

FIG. 52 shows that the roller 201 rests against the side edge 351a of the contact element 351 after the counterclockwise movement with the printing cylinder has taken place. The opening and closing arm 202 has thus pivoted counterclockwise. When the dog sinä opened after the counter-clockwise movement of the arm 202 204 ₇ v / ith the hell 209 engaged with the smaller Durohmesserteil 210a of the fixed Nooke 210th The front ends of the ejection claws 204 therefore protrude outward so that the front end of the pattern 19a is released from the printing cylinder 15. A further rotation of the pressure cylinder brings the roller 209 into engagement with the larger diameter part of the nooke 210, so that the ejection claw 207 is retracted and the gripping claw 204 is held in the open position by the contact element 351. As a result of a further rotation of the printing cylinder, the pattern 19a is guided through the Abechälklauen 349 according to FIGS. 53 and into the trough-like receiving device according to Pig provided for this purpose. 1 introduced. The pattern or the lithographic plates are ejected due to the continuous rotation in counterclockwise

When the role is to rest with the contact element 351 according to Pig. 54 is brought, the locking member 407 and a bent part 343 a of the engaging arm 343 by a strong force engaged with each other · This prevents the oscillating plate 340 pulled by the spring 362 on movement of the engaging arm 343 by the Pin 345. When the roller 201 is out of engagement with the contact element 351 according to Pig. 55 is released, the locking element 407 sucked through the peder 356 and a little counterclockwise within the confines of the slot 354 moves. This maintains the force with which the locking member 407 is held in engagement with the bent part 343a is reduced so that the oscillating plate 340 is released from the locked position. The oscillating plate 340 is thus returned to its original position by the force of the peder 362. The device To remove the patterns and lithographic plates, they are also returned to their original position (see Fig. 51). A movable rod 341 of the solenoid 319 becomes inoperative before the roller 210 disengages is released with the contact element 351.

If, according to Pig. 51 the solenoid 319 is energized when the roller 201 is in the position 201A shown with dashed lines, the contact element 351 prevented by the roller 201 from pivoting and the engaging member 407 is prevented from pivoting in the clockwise direction. Since springs 356 and 344 are between the locking element 407 and the connecting rod 353

and between the oscillating plate 340 wxc the engagement arm 343 are respectively arranged “ h & rm. the oscillating plate 340 pivot counterclockwise against the action of the springs 356 and 344, causing the solenoid 319 to be energized as described above. When the roller 201 comes out of engagement with the part 351 after the oscillating plate 340 has moved counterclockwise, the pattern can be removed from the printing cylinder 15. This removal operation is carried out when the roller 201 is in contact with it the contact element 351 j as described above, comes.

The duplicating and decking device according to the invention is designed so that the washing and cleaning of the cylinder 16 during the removal of the pattern from the cylinder 15 is carried out »The command to begin with the washing of the cylinder 16 is given by a solenoid 363 as shown in FIG. 56, which with a movable Rod 364 is provided, which is connected by a compression spring 367 to an oscillating plate 366, which is through one to the side plate of the duplicator ^ connected shaft 365 is rotatably supported.

For example, an electromagnetic clutch 374 is disposed external to the right side plate of the duplicator. One in one piece with a Plansch 375 connected gear 376 is rotatably disposed on shaft 373. A flap 377 connected to the shaft 373 is between the flap 375 and the electromagnetic one Coupling 374 arranged.

The gear 376 meshes with a gear 378 which is arranged on the outside of the right side plate of the reproduction device. The gear is with one One end of a stump wolf connected to the other End carries a gear 379 which is located within the right side plate and meshes with a gear 381, which can be driven by a drive wheel 380 connected to an end face of the cylinder 16 · Die Rollers 370 and 372 are provided with gears 382 and 383 in the area of their respective shafts, which with one another comb.

56 shows the magnetic coil 363 in the operating position, in which the oscillating plate 366 by the movable Rod 364 is pulled towards solenoid 363. A relatively weak peder 384 is oscillating between the Plate 366 and a fixed part of the machine arranged to retrieve the oscillating Plate 366 is used in the original position when the solenoid 363 is ineffective. The support plate 571 is normally caused by a peder with a relatively high pederungsvexTnöng pressed clockwise around shaft 373. An outwardly directed curved projection 371a of the plate 371 is normally engaged with one

Lock arm 368 and thereby locked.

Since the oscillating plate 366 rotates clockwise due to the action of the spring 367, the lock arm 368 is rotated about the shaft 365 by the action of the peder 369. The locking arm 368 is prevented from rotating and pivoting because it is locked by engagement with the outwardly directed curved portion 371a of the support arm. When a protrusion 385a of a nooke 385 attached to an end face of the printing cylinder presses a roller 386 disposed on the support plate 371 and displaces the support plate 371 a little clockwise after energizing the solenoid 363, the force _s becomes engaged with that of the bent portion 371a with the engaging arm 368 is reduced, so that the locking arm 368 pivots due to the action of the peder 369. The support plate 371 is thus released from the locking engagement with the locking arm 368 and can rotate in the counterclockwise direction, so that the washing and cleaning roller 370 is pressed against the circumferential surface of the cylinder 16. The shaft 373 is freely rotatable with respect to the toothed wheel 376 when the electromagnetic clutch 374 remains inactive, so that the washing and cleaning roller 370 is turned counterclockwise (see Fig. 56) by the cylinder onto the squeegee roller 372 which is immersed in a liquid of a "liquid source" 387 and supplies liquid to the roller 370 for removing the print = · color image on the cylinder 16.

The washing and cleaning can be done very easily and quickly if the electromagnetic clutch 374 is actuated. When operating the electromagnetic

4449 009827/1407

Coupling 374, the flaps 375 and 377 are brought into engagement with one another and act as a unit. The gear 376 is driven by the drive gear 380 via the gears 381, 379 and 378, so that the gear 376 rotates in the direction of the arrow. The rotation of gear 376 is transmitted to gear 383 and then to gear 382. Therefore, the roller 370 rotates in the direction of the arrow in Fig. 56 or in the same direction as the cylinder 16. The relative speeds of the cylinder 16 and the roller 370 in the area of their contact with one another standing circumferential surfaces are enlarged, whereby washing is accelerated. To avoid any damage to the contact surfaces of the cylinder 16 and the roller 370, for example due to rubbing effects, the roller 370 is preferably made of felt or some other soft material Material made.

The length of time for washing is set in advance regardless of whether the electromagnetic clutch is used. When the preselected and set time has elapsed, the solenoid 363 is made ineffective and the lock arm 368 is returned to its original position. The protrusion 385a on the Nooke 385 so pushes the hollow 386 outward, so that the locking arm 368 comes into engagement with the support plate 371 and this this locks.

As soon as the washing is finished, the command to feed a copy sheet such as a foil is given. The for this provided feed device is ineffective if A transparency or a sheet is fed into the duplicator has been. This one sheet is used to keep the Waaohflüe-

sigkeit from the outer peripheral surface of the cylinder 16 to remove and a mark between the foils that have already been printed and those to be printed in the next cycle admit.

When the duplicator or duplicator has previously been set to operate continuously the next lithographic plate or print pattern is automatically followed by the duplicator ^ Feed of the single sheet, fed and the aforesaid cycle is repeated.

In Fig. 1, a print copy number-IjeseeinriQhtaig 400 is shown, which are arranged above one end of the printing cylinder 15 is. The edge of one on the pressure cylinder 15 at »

In the example shown, a data mark D1 corresponds to a count mark 1, a data mark D2 corresponds to a count mark 5, a data mark D3 corresponds to a count mark 2 and a data mark D4 corresponds to a count mark 0. It follows that the number of copies to be duplicated is 1520. This number is indicated by an indicator tube on the duplicator or printer.

The reading device is provided with a photoelectric transducer element 402d for reading the data marks / with a photoelectric transducer element 402t for reading the setting and counting marks. A start mark S is printed on the lithographic plate in alignment with the data marks which extend in the longitudinal direction. When the plate rotates together with the plate cylinder 15 in the direction of arrow A, the photoelectric transducer element reads 402d initially the start mark S. Then, the data and counting indicia are read by the corresponding elements. is provided with cutouts for fixing the plates, the printing or plate cylinder. means must be _provided? preventing a start of the reading in the incidence of light , which is reflected by one of these cutouts onto the photoelectric converter cell. The start mark S is arranged and designed in such a way that reading did not begin: »Before the start mark has been read.

As. Pig. 32, the data mark scanning circle generated pulse-shaped signals fed to a threshold circuit to determine whether the pulses actually created by the data marks. The pulses are then fed to a buffer store. The pulses generated by a counting mark reading circuit are sent to the buffer and a carry counter fed. The signals generated simultaneously by the carry counter and the intermediate register are sent to a "

Transfer data register. The number of printed copies and copies stored by this counter, is displayed by a display device.

The pulsed signals that are generated each time when a copy sheet is printed, a circle for counting the number of copies printed and copies are fed. When the number of copies printed is equal to the number of copies stored in the data register is, a signal is transmitted from a coincidence circuit to an end-of-print signal generator, which generates a signal which makes the magnetic coil of the device for feeding (the individual sheets ineffective.

According to the invention, the periods of time for etching, for applying the paint and for washing the cylinder 16 are shown set after the main switch has been turned on. To save the time intervals that have been set an electrical or a mechanical timer can be used.
