US Pat. No. 4,178,848 discloses an apparatus for automatically feeding printing forms to a forme cylinder, wherein printing forms having non-folded ends are stored in a stack inclined in the feeding direction and driven by rollers via a feed line in front of the stack Conveyor belt sequentially fed to the forme cylinder, wherein each of the lowermost located pressure mold is pulled at its leading end with a sucker from the stack. This very long-building device is not suitable for printing forms with folded ends. Moreover, when pulling out of the directly stacked printing forms there is a risk of damaging their printed image pages.

The invention has for its object to provide an apparatus for storing a cylinder to be fed to a printing press elevator.

The object is achieved by the features of claim 1.

The advantage achievable with the invention is, in particular, that several lifts on a cylinder can be changed quickly and reliably at the same time or at least in a very rapid sequence on a cylinder. The elevator falls due to the operation of a holding member from a vertically upper storage position to an underlying storage position, from which it can be transported to the cylinder. By the actuation of the holding element of the stored elevator changes in free fall from its vertical upper storage position in the underlying storage position. The actuation of the holding element is preferably carried out with a controllable drive and can thus be made by machine. When changing the storage position of an elevator stored in the magazine remains to be changed in its storage position elevator during the change process in the magazine, the change is triggered by a controllable machine element of the magazine. An elevator to be changed in its storage position is not exposed to the risk that its surface will be damaged when changing. The device is also suitable for in particular in their length flexurally elastic elevators with folded at their ends Einhänbringeln. Moreover, the device builds extremely flat in their height so that they do not hinder the required accessibility to the printing unit.

B. between 360 mm and 600 mm and for the width B z. B. between 250 mm and 430 mm. The surface has a support side, which is referred to below bearing surface 02, with which the elevator 01 rests in the arranged on a lateral surface 07 of a cylinder 06 state (Fig. 2). The rear side of the support surface 02 is a work surface which, in the event that the elevator 01 is formed as a printing forme 01, is provided with a printed image or at least can be provided with a printed image. The elevator 01 has two opposite ends 03; 04 preferably each with angled Einhänbringeln 13; 14, wherein the ends 03; 04 limit the bearing surface 02 and wherein the suspension legs 13; 14 each preferably extend entirely or at least partially above the width B of the elevator 01. The contact surface 02 of the elevator 01 is flexible at least along the length L and, in the case of an arrangement of the elevator 01 on the lateral surface 07 of the cylinder 06, its curvature can be adapted (FIG. 2). When the printing forme 01 is arranged on the lateral surface 07, the length L of the bearing surface 02 thus extends in the direction of the circumference of the cylinder 06, whereas the width B of the bearing surface 02 extends in the axial direction of the cylinder 06.

A rectified with the production direction P of the cylinder 06 end 03 of the elevator 01 is referred to as the extending end 03, whereas the opposite End 04 is the trailing end 04 of the elevator 01. At least the ends 03; 04 of the elevator 01 with the suspension legs 13 formed thereon; 14 consist of a rigid, z. B. metallic material, eg. B. of an aluminum alloy. Usually, the material thickness D of the elevator 01 (FIG. 1) or the material thickness D is at least from the suspension gifts in FIG. 14 a few tenths of a millimeter, z. B. 0.2 mm to 0.4 mm, preferably 0.3 mm. Thus, the elevator 01 as a whole or at least at its ends 03; 04 made of a dimensionally stable material, so that the ends 03; 04 are permanently deformable by bending against a material-specific resistance.

At least at one end 03; 04 of the elevator 01 (FIG. 1), but preferably at both ends 03; 04 are along a bending edge 11; 12 each a folded suspension leg 13; 14 formed, wherein the suspension legs 13; 14 in a narrow, in particular slot-shaped opening 09 of the channel 08 of the cylinder 06 (FIG. 2) insertable and there by means of a holding device, for. B. a clamping device can be fastened. For example, based on the length L of the non-curved, flat bearing surface 02 of the uninstalled elevator 01 at the end 03 a suspension leg 13 at the bending edge 11 by an opening angle α1 or at the end 04 a suspension leg 14 at the Blegekante 12 by an opening angle β1 bent (Figure 1), wherein the opening angle α1; β1 usually lie between 30 ° and 140 °. If the opening angle α1 is assigned to the leading end 03 of the elevator 01, it is preferably executed at an acute angle, in particular it is 45 °. The opening angle β1 at the trailing end 04 of the elevator 01 is often preferably greater than 80 ° or obtuse-angled, in particular it is 85 ° or 135 °. The folded suspension leg 13 at the leading end 03 has a length 113, soft z. B. in the range of 4 mm to 30 mm, in particular between 4 mm and 15 mm. The bent suspension leg 14 at the trailing end 04 has a length 114, the z. B. 4 mm to 30 mm, in particular between 8 mm and 12 mm, with the shorter length measure is preferred to simplify removal of the suspension legs 13 as possible; 14 to ensure from the opening 09 of the channel 08. Fig. 2 shows a simplified sectional view of a cylinder 06 with a lateral surface 07 and a channel 08, which has a narrow slot-shaped opening 09 with a slot width S to the lateral surface 07, wherein the slot width S is less than 5 mm and preferably in the range from 1 mm to 3 mm. The opening 09 has a front edge 16 and a rear edge 17 in the production direction P of the cylinder 06. Between the extending from the front edge 16 to the channel 08 toward wall 18 and an imaginary, resting on the lateral surface 07 of the cylinder 06 on the opening 09 tangent T09 an acute opening angle α2 is formed, which is between 30 ° and 50 °, preferably 45 ° is. The bent suspension leg 13 at the leading end 03 of the elevator 01 is thus preferably positively connected to this front edge 16 of the opening 09, because the opening angle α1 at the leading end 03 of the elevator 01 is preferably adapted to the opening angle α2. In the same way it behaves at the trailing end 04 of the elevator 01. Between the extending from the rear edge 17 to the channel 08 toward wall 19 and an imaginary, resting on the lateral surface 07 of the cylinder 06 on the opening 09 tangent T09 is an opening angle β2, which is either between 80 ° and 95 °, preferably 90 °, or between 120 ° and 150 °, preferably 135 °. The bent suspension leg 14 at the trailing end 04 of the elevator 01 is thus preferably positively clamped at this rear edge 17 of the opening 09, because the opening angle β1 at the trailing end 04 of the elevator 01 is at least approximately adapted to the opening angle β2.

In the channel 08 are z. B. at least one preferably pivotally mounted holding means 21 and a preferably biased spring element 22 is arranged, wherein the spring element 22, the holding means 21 z. B. against the folded suspension leg 14 at the trailing end 04 presses, which is hooked to the opening 09 at its rear edge 17, whereby the suspension leg 14 at the trailing end 04 at the extending from the rear edge 17 to the channel 08 extending wall 19 becomes. To release the pressure exerted by the holding means 21 pressure in the channel 08 is an actuating means 23, preferably a pneumatically actuable adjusting means 23 is provided, which pivots the holding means 21 against the force of the spring element 22 during its actuation. The holding device described by way of example consists essentially of the holding means 21, the spring element 22 and the adjusting means 23.

The exemplified cylinder 06 is preferably such that on its lateral surface 07 a plurality of, preferably similar elevators 01 can be arranged. If the cylinder 06 is designed as a forme cylinder, it can in its axial direction side by side z. B. with up to six plate-shaped printing plates 01 are occupied. It is also preferably provided that more than one elevator 01 can be arranged on the cylinder 06 in the direction of its circumference. Thus, in the cylinder 06 under the lateral surface 07 z. B. two axially extending to the cylinder 06 channels 08 may be provided, which have for attachment of elevators 01 axially to the cylinder 06 extending openings 09, wherein the openings 09 at the periphery of the cylinder 06 z. B. offset by 180 ° to each other, if two elevators 01 are to be arranged on the cylinder 06 along its circumference one behind the other. In this assignment of the cylinder 06 with two along its circumference successively arranged elevators 01, the leading end 03 of the one elevator 01 is fixed in the one channel 08, whereas the trailing end 04 of the same elevator 01 is fixed in the other channel 08. For the or the other arranged on this cylinder 06 lifts 01 applies accordingly. If several elevators 01 are arranged next to one another in the axial direction of the cylinder 06, they can advantageously also be arranged offset to one another. The offset can z.

B. as a rolling element 24, in particular as a roller 24 or as one or more axially to the cylinder 06 juxtaposed rollers 24 may be formed, the or z. B. in the function of a pressing member 24 to the cylinder 06 is adjustable or are. The support element 24 is preferably arranged close to the cylinder 06.

The leading end 03 of the elevator 01 can also be brought so against the cylinder 06, that this end 03 after its contact with the lateral surface 07 of the cylinder 06 at an acute angle γ with an imaginary, in a contact point 29 on the lateral surface 07 of the Cylinder 06 lying second tangent T29 averted from the lateral surface 07 of the cylinder 06 (illustration of the elevator 01 in Fig. 4 with a solid line). The thus performed bending of the leading end 03 of the elevator 01 should, however, only be so strong that the suspension leg 13 attached there still rests securely against the lateral surface 07 of the cylinder 06. To support the safe concern of Einhängeschenkeis 13 on the lateral surface 07 of the cylinder 06 can, for. B. the support member 24 to the elevator 01 are employed, whereby the elevator 01 is held with its leading end 03 close to the lateral surface 07 of the cylinder 06.

It is advantageous, the forme cylinder 31; 33 seitenregistermäßig in a predefined position to bring him z. B. with respect to the page register to zero, before there is an exchange of a printing plate 36; 37 between the forme cylinder 31; 33 and the printing form magazine 38; 39 is coming. Alternatively to the setting of the forme cylinder 31; 33 can also be the printing form magazine 38; 39 laterally relative to the forme cylinder 31; 33 are brought into a predefined position, so that the exchange of a printing plate 36; 37 between the printing form magazine 38; 39 and the forme cylinder 31; 33 can be targeted and without lateral displacement.

It is advantageous to arrange an articulated, preferably pivotable guide plate 49 close to the forme cylinder 33 in front of the opening of the printing forme magazine 39 which can be directed onto the forme cylinder 33 (FIG. 5), with which a trailing end 04 of a printing forme released from an opening 09 in the forme cylinder 33 is located 37 directed to the shaft 42 for receiving the abzunehmenden printing form 37 is passed. In particular, an erroneous access to the shaft 44 is obstructed with the guide plate 49 for a printing plate 37 to be removed from the forme cylinder 33, in which at least one new printing plate 37 is provided or at least ready for delivery. Likewise, the attachment of a guide plate 49, which is not shown in FIG. 5 for the sake of clarity, may also be advantageous at the printing forme magazine 38 arranged below the paper web 46 and cooperating with the forme cylinder 31.

Another embodiment of a printing press with printing forme magazines results in conjunction with a printing machine, for. As a multi-color offset printing machine, the printing units preferably in bridge design or a compact design, ie a low in construction height printing machine with eight pressure points, as it is exemplified in FIG. 36, in at least one frame 97 on a foundation 96 are arranged one above the other , A printing material 46, preferably a paper web 46, is in this case fed to the printing press and passed vertically through the printing units. In the example shown in FIG. 36 four successive printing units in the direction of transport of the paper web 46 are shown to the right and left of the paper web 46 each have a transfer cylinder 32; 34 with a form cylinder 31; 33, wherein in a printing unit on the paper web 46 opposite transfer cylinder 32; 34 roll on each other. The paper web 46 is z. B. introduced by means of a first printing unit arranged first paper guide roller 92 to the first printing unit and derived by means of a fourth printing unit arranged second paper guide roller 93 from the fourth printing unit. Each form cylinder 31; 33 is associated with at least one inking 94, the details of which will not be discussed here. Each form cylinder 31; 33 is a printing form magazine 38; 39, each preferably two shafts 41; 42; 43; 44 has. As in the embodiment previously described in connection with FIG. 5, here too each printing form magazine 38; 39, but at least its storage position for a printing form 36 to be stored; 37, in the working position preferably substantially horizontally or only with a slight inclination of less than 15 ° to the mold cylinder 31; 33 aligned. In the working position of the printing form magazine 38; 39 is at least one printing plate 36; 37 between the shafts 41; 42; 43; 44 and the forme cylinder 31; 33 interchangeable, either by a no longer required to execute a print job 36; 37 from the forme cylinder 31; 33 removed and into the shaft 41; Introduced 42 or a new to execute the print job printing plate 36; 37 from the shaft 43; 44 brought out and on the forme cylinder 31; 33 is mounted. The structural features of the printing form magazines 38; 39 may correspond to those of the embodiment described above in connection with FIG. 5 in this embodiment. It is advantageous if the implementation, in particular the completion of a printing form change is monitored by sensors. Likewise, the printing form magazines 38; 39 in conjunction with the form of cylinders 31; 33 controllable such that preferably from a printing press associated control station from selectively a printing plate change can be initiated. Because the printing form magazines 38; 39 during an ongoing production of the printing press can be prepared for a printing plate change, the standstill of the printing units requiring setup time is reduced to an extremely short period of z. B. less than two minutes, preferably less than ninety seconds, for a complete change of all printing plates 36; 37 in this Printing press arranged printing units. Depending on the design of the printing units z. B. ninety-six printing plates 36; 37 at the same time in use. Such a rapid printing plate change even with a larger number of printing plates 36; 37 greatly increases the economics of the press because of its extremely short downtime.

Further details regarding a method and a device for carrying out the method will now be explained by way of example with reference to FIGS. 6 to 35. FIG. 6 shows a forme cylinder 33 with two channels 08 offset on the circumference by 180 ° and two printing forms 37 arranged one behind the other along the circumference, wherein the suspension leg bent at right angles. 14 on each in the production direction P of the forme cylinder 33 trailing end 04 of each printing plate 37 each held by a channel 08, held by a spring element 22 pressurized holding means 21 on a wall 19, wherein the wall 19 of a rear edge 17 of the channel 08th opening opening 09 to the channel 08 extends, wherein the holding means 21 can be released by the operation of a spring element 22 counteracting pneumatic actuator 23. At the extending from the front edge 16 of the same opening 09 to the channel 08 toward wall 18 of the acute-angled bent suspension arm 13 is applied form-fitting manner at the leading end 03 of the other along the circumference of the forme cylinder 33 arranged printing form 37. For details on the mounting of the printing plates, reference is made to FIG. 2.

Fig. 6 also shows an engageable by pneumatic actuation of the forme cylinder 33 pressure element 24 in the form of a pressure roller 24 or pressure roller 24. Also close to the forme cylinder 33 is a parallel to the axial direction pivotally mounted alignment device 51 arranged with two diametrically laterally on a printing plate 37 acting, wing-shaped stops 52; 53 provided, wherein the alignment device 51 each with one of their stops 52; 53, a printing plate 37 to be mounted temporarily fixed during its feeding to the forme cylinder 33. The stops 52; 53 z. B. each formed as a lateral guide plate, wherein the stops 52; 53 z. B. on a pivotable Traverse, z. B. a square tube are arranged. The stops 52; 53 differ z. B. in their position based on the axial direction of the forme cylinder 33, so that z. B. for a printing plate 37 simple width of the stop 52 and for a printing plate 37 in the panoramic size of the stopper 53 is brought by a corresponding pivoting of the alignment device 51 is used. The stops 52; 53 can be axially adjustable to the forme cylinder 33 for the required width of the printing plate 37.

FIG. 6 also shows further details of the printing forme magazine 39. The embodiment shown in FIGS. 6 to 35 is based on a variant for the printing forme magazine 39, in which an upper shaft 44 for providing a printing forme 37 to be mounted on the forme cylinder 33 as an independent structural unit independently of a lower shaft 42 for receiving a from Form cylinder 33 removed print form 37 is operable. Both shafts 42; 44 can be used as individually and independently usable and thus independently functional units. This application is of interest if z. B. only the feed of the forme cylinder 33 is to be automated with new printing plates 37, whereas the decrease of used printing plates 37 is performed by an operator. If both shafts 42; 44 are formed in the printing forme magazine 39, results in a fully automatic printing form changer. Both shafts 42; 44 each have all necessary for storing and conveying of printing plates 37 devices and are preferably constructed very compact. In particular, they have despite their capacity of at least two printing plates 37 a low overall height. The height is z. B. less than 150 mm, preferably less than 100 mm.

In the embodiment shown in FIGS. 6 to 35, the shaft 44 is arranged horizontally and oriented tangentially to the forme cylinder 33. As a result, the force FG exerted on the printing form 37 is used in the best possible way to support functions described below. In the shaft 44 is a support 54, on which a to be mounted on the forme cylinder 33 first printing plate 37 with its folded Einhänbringeln 13; 14 can be set up or stored. A stored on the pad 54 printing form 37 is located there z. B. with their entire extended length L on.

The pad 54 is preferably not the entire surface, but in the form of parallel strips 54 or slides 54 formed. The suspension leg 14 at the trailing end 04 of the first printing plate 37 is located in the shaft 44 on the side remote from the forme cylinder 33 on a preferably vertical stop 56, the stop 56 of a conveyor 57 linear and parallel to the support 54 in the direction of opening o39 the printing forme magazine 39 is movable in order to convey this first printing forme 37 out of the shaft 44 by a translatory movement and preferably without deformation until the suspension leg 13 can reach the slot-shaped opening 09 of the forme cylinder 33 at the leading end 03 of this first printing forme 37. The stopper 56 thus serves in the slot 44 for the first printing plate 37 as an abutment position and at the same time has the function of a slider 56. If this first printing plate 37 has at the trailing leg 14 at its trailing end 04 at least one register punching, the stop 56 z. B. advantageously also as a perpendicular to the support 54 standing, connected to the conveyor 57 register pin 56 may be formed so that with the application of the first printing form 37 to the stop 56 for them a Vorregisterung takes place with respect to their side register. The conveyor 57 is z. B. as a belt drive 57 or as a linear drive 57, preferably as a pneumatic linear drive 57, in particular as a rodless, double-acting linear actuator 57 is formed

In the shaft 44 is a holder 58, in particular printing form holder 58 for holding at least a second on the forme cylinder 33 to be mounted printing plate 37. As shown in Fig. 13, the second printing plate 37 from the printing form holder 58 above the support 54, ie at a distance a54 above the edition 54 z. B. thereby, that the printing form holder 58, for example, on the side facing away from the forme cylinder 33 has a movable parallel to the support 54 piston 59 or slider 59, at the end of a holding element 61, z. B. L-shaped angle 61, is arranged, wherein the second printing plate 37 above the support 54 between the angle 61 of the extended slider 59 and in the region of the opening o39 of the printing forme magazine 39 arranged further holding element 62, z. B. a rigidly arranged stop 62 is clamped. The distance a54 has a value, which is preferably between twice and four times the length I14 of Einhänlegeels 14 at the trailing end 04 of the second printing plate 37. The clamping of the second printing forme 37 takes place in that a clear distance a58 between the angle 61 of the extended slider 59 and the stop 62 is set shorter than the extended length L of the second printing forme 37. The stop 62 in the region of the opening o39 of the printing forme magazine 39 preferably has a chamfer 63 on which the suspension leg 13 can be supported on the leading end 03 of the second printing plate 37, wherein the chamfer 63 of the stopper 62 and the L-shaped angle 61 at which the suspension leg 14 at the trailing end 04 the second printing form 37 is supported, facing each other. Since the second printing plate 37 is flexible, in particular along its length L, it bulges in its clamped state between the angle 61 and the stop 62. The slider 59 of the printing plate holder 58 is preferably linearly movable parallel to the support 54 and preferably has two stable operating positions, namely a stable operating position in the retracted, the second printing plate 37 releasing state and in the extended, ie the second printing plate 37 clamping state. In a variant of the printing form holder 58, the arrangement of the movable slide 59 and rigid stopper 62 are interchanged, so that the slider 59 is in the region of the opening o39 of the printing forme magazine 39 and the stop 62 on the side remote from the forme cylinder 33 side. As an alternative to the described linear mobility, the angle 61 or the stop 62 can also be arranged to be pivotable about a pivot axis aligned parallel to the width B of the printing forme 37. A clamped between the angle 61 and the stop 62 printing plate 37 is located at its upper or first storage position, while a stored on the pad 54 printing plate 37 assumes a lower, second storage position in this state, the printing plate 37 in the second storage position before her Transport to the forme cylinder 33 is cached. By an operation, preferably by a remote from, z. B. from a belonging to the press console control changes the printing plate 37 within the shaft 44 from its upper, first storage position to its lower, second storage position, in the first storage position and stored in the second storage position printing plates 37 are from each other spaced, z. B. along their length L with the distance a54, so they do not touch each other and therefore can not damage.

Another embodiment of the printing plate holder 58, which advantageously allows a particularly low overall height for the shaft 44, provides the second printing forme 37 above the support 54 extending in a single plane in the axial direction of the forme cylinder 33 with at least one retaining element 64 in an upper storage position to hold, with the retaining element 64 z. B. as a guide rail 64, preferably as two mutually parallel guide rails 64, is formed (Fig. 7 to 9), wherein the guide rails 64, the second located in the shaft 44 printing plate 37 at its two longitudinal sides along at least a part of their. Keep length L in the upper storage position. The design of the printing form holder 58 with guide rails 64 assumes that the suspension legs 13; 14 at the ends 03; 04 of the second printing form 37 do not extend over the full width B of the printing plate 37 by not reaching the longitudinal sides of the printing plate 37. The longitudinal sides of the printing plate 37 thus form in the region of the support surface 02 of the printing plate 37 a projection against the Einhängeschenkein 13; 14. This projection is necessary to make the printing plate 37 in the guide rails 64 feasible. The holding element 64, in particular each guide rail 64, z. B. from a U-shaped, each one of the longitudinal sides of the printing plate 37 with a certain play encompassing strap into which the second printing forme 37 is inserted from the side facing away from the forme cylinder 33 side. The second printing form 37 is thus held by the guide rails 64, preferably in a narrow region of its side, wherein the holder acts in particular as a vertical support and thus as a support against the force acting on the printing plate 37 gravity FG. The guide rails 64 are preferably made of a dimensionally stable material such as metal or plastic.

In order to deposit a second printing forme 37 held on the support 54 by the guide rails 64, at least one of the guide rails 64 is movable in the direction of the width B of the second printing forme 37. Preferably, however, both guide rails 64 along the width B of the second printing plate 37 in opposite directions so that they move away from each other at least temporarily and increase their distance from each other so that they no longer support the longitudinal sides of the printing plate 37 vertically, whereby the second printing plate 37 due to the force acting on her gravity FG between the guide rails 64 passes through on the support 54 If the holding element 64 in a first operating state, the second printing forme 37 z. B. holds by an electric or magnetic force in the upper storage position, the holding member 64 preferably changes remotely from its first operating state to a second operating state, wherein the second operating state causes the holding member 64 that the printing plate 37 and the holding member 64 from each other and the printing forme 37 upon release from the retaining element 64 in the shaft 44 by a free fall and thus alone by the force acting on her gravity FG in the preferably immediately vertically below the upper storage position lying storage position changes. The second printing plate 37 is held in the lower and also in the upper storage position in the shaft 44 at an inclination of less than 15 °, preferably horizontally. At least the guide rails 64 designed as a support bearing for the second printing forme 37 have in their longitudinal extension only this slight inclination or a horizontal course.

A release of the second printing forme 37 from the laterally engaging guide rails 64 is preferably supported by a stop 67 standing perpendicular to the support surface 02 of the second printing forme 37, which is preferably arranged rigidly in the slot 44, preferably on both longitudinal sides of the second printing forme 37 such stop 67 is arranged so that during a along the width B of the second printing form 37 directed, opposite movement of the printing plate 37 holding guide rails 64 this printing forme 37 stored by the stops 67 arranged on both sides in the plane spanned by the support surface 02 of the printing plate 37 level remains. The stops 67 strip the printing plate 37 from the mutually removing guide rails 64 by the printing plate 37 abuts against the stops 67, at the same time the printing plate 37 by the movement of the guide rails 64, the vertical support is withdrawn. Solving the second printing plate 37 is preferably carried out by a z. B. controllable by the press belonging to the control station drive 69, the drive 69 acts on the guide rails 64 and moves them along a travel s68.

If several printing plates 37 are arranged side by side on the forme cylinder 33 in the axial direction thereof and a plurality of printing plates 37 are arranged side by side in the shaft 44 in the axial direction of the forme cylinder 33, it is advantageous for the guide rails 64 which act on adjacent second printing plates 37 to be in the printing forme magazine 39 Edition 54 in two different levels, d. H. arranged vertically offset from each other, wherein in the axial direction of the forme cylinder 33 successive planes are preferably arranged alternately offset. Due to the staggered arrangement of the first storage position of the printing plates 37 forming levels can be a distance a67 between in the axial direction of the forme cylinder 33 side by side, d. H. adjacent arranged printing plates 37 are kept as low as possible. The distance a67 preferably corresponds in its value to a distance which is adjacent to one another on the forme cylinder 33 in its axial direction, ie. H. have adjacently arranged printing plates 37. From in the axial direction of the forme cylinder 33 juxtaposed planes, d. H. in each case from a first storage position, placed on the support 54 and thus placed in their second storage position printing plates 37 can be fed to the form cylinder 33 either individually or preferably simultaneously with the conveyor 57, the latter approach for a quick change of printing plates 37 on the forme cylinder 33 is advantageous. In the axial direction of the forme cylinder 33 stored in different juxtaposed planes printing plates 37 can change simultaneously or at least in rapid succession in their respective second storage position. The form cylinder 33 at the same time jointly supplied printing plates 37 are arranged on the forme cylinder 33 in the axial direction side by side,

In the example shown in FIG. 8, four second printing plates 37 are each juxtaposed in their first storage position in the axial direction of the forme cylinder 33, each of these printing plates 37 each being mounted at their longitudinal sides in a guide rail 64 is held. The vertical offset of the printing plates 37 is only a few millimeters, z. B. 4 mm to 6 mm, and corresponds approximately to the overall height of the guide rails 64, preferably their simple to double height. The movement of the guide rails 64 along the width B of the second printing form 37 is z. B. by a linear displacement of the guide rails 64; However, it can also be performed by a pivoting movement of the guide rails 64, wherein the guide rails 64 are pivotable about a pivot axis, wherein the pivot axis parallel to the supported by the guide rails 64 side of the printing plate 37. Thus, a guide rail 64 z. B. attached to at least one pivot arm 68, the z. B. in the plane spanned by the bearing surface 02 of the second printing plate 37 plane is pivotally, which is indicated in Fig. 9 by a directional arrow. The pivot arm 68, one end of which is connected to the guide rail 64 and the other end in the shaft 44 is preferably fixedly mounted, z. B. as a laterally acting on the guide rail 64 spring element 68, z. B. may be formed as a leaf spring 68, wherein the guide arm 64 connected to the pivot arm 68 by the drive 69, z. B. by a controllable, in particular remotely controllable magnet 69, in a second printing forme 37 holding or one of this printing plate 37 releasing operating position is moved. The travel s68, the movable guide rail 64 performs along the width B of the second printing plate 37, is in the range of a few millimeters, z. B. between 2 mm and 10 mm, preferably 4 mm. Preferably, a stop 67 is also provided in this embodiment, to which the printing plate 37 abuts with its supported by the guide rail 64 side, while the guide rail 64 withdraws the support by their movement of the printing plate 37. Two adjacent pressure plates 37 in the axial direction of the forme cylinder 33 can strike on opposite sides of the same stop 67. During the change from the upper storage position to the lower storage position, the printing forme 37 can also slide vertically downward along one of its sides with the stop 67 so that the printing forme 37 released from the upper storage position reaches the lower storage position in a guided movement. The stopper 67 then has the function of a preferably up to the support 54 for a printing form 37 which changes its storage position reaching lateral guidance.

In general terms, a method of storing at least two of the same cylinder 06; 31; 33 of a printing press successively discharged elevators 01; 36; 37 the following steps: a) a previously from the cylinder 06; 31; 33 discharged elevator 01; 36; 37 is transported from a first to a second storage position, b) the previously discharged elevator 01; 36; 37 subsequently discharged elevator 01; 36; 37 is at the first storage position of the previously discharged elevator 01; 36; 37 stored, c) the previously discharged elevator 01; 36; 37 in its second storage position and the subsequently discharged elevator 01; 36; 37 in the first storage position of the previously discharged elevator 01; 36; 37 are stored in a distance orthogonal along their length L, d) the elevators 01; 36; 37 are stored in their respective support surface 02 at least largely overlapping, preferably at least 80% overlapping or stored in their complete or almost complete coverage. The previously discharged elevator 01; 36; 37 and the subsequently discharged elevator 01; 36; 37 can be stored along their length L vertically or horizontally spaced from each other. Preferably, the previously discharged elevator 01; 36; 37 transported by a linear movement, in particular by a both memory positions directly and directly interconnecting linear movement orthogonal to its support surface 02 or by a movement of its trailing end 04, in its second storage position, which will be explained in more detail below.

It is advantageous, in particular in the shaft 44, for example on the slider 56 for a bearing on the pad 54 first printing form 37 or at the L-shaped angle 61 for a second printing plate 37 to install a code reader 71, each one preferably on the suspension leg 14th at the trailing end 04 of each printing plate 37 attached coding reads, ie detects a feature for identifying a printing form to check in a preferably electronically carried out in a control unit comparison with a provided for the forme cylinder 33, stored in the control unit occupancy plan, whether in the Shaft 44 introduced printing forms 37 correspond to the allocation plan of the intended printing operation and whether for the intended occupancy introduced into the slot 44 printing plates 37 are also in the correct order. Thus, even before the assembly of the printing plates 37 on the forme cylinder 33, a corresponding message, eg. B. an error message, ie a warning the operator before a faulty installation message generated and z. B. deposited on a printing unit associated control station and displayed there or on the printing unit.

The coding may preferably be in addition to a human-readable code z. B. be designed as a barcode. The code reader 71 is thus preferably arranged in the shaft 44 at its end facing away from the forme cylinder 33, wherein a reading direction of the code reader 71 is directed either parallel to the length L of the printing plate 37 or preferably parallel to the width B of the printing plate 37. In a preferred embodiment, the code reader 71 is preferably arranged with a linear guide movable in or on the shaft 44 or there is a preferably inclined by 45 ° to the width B of the printing plate 37 movable mirror which provides a detection or read signal from one to the printing plate 37 attached code to a arranged on one side of the shaft 44 code reader 71 deflects, so that only a single code reader 71 is required for reading the attached to the stored in the wells 44 printing plates 37 coding. By using only a single code reader 71 for a plurality of stored printing plates 37, significant costs can be saved. In the case of the use of only a single code reader 71, the code reader 71 or the mirror is either parallel to the width B of the printing plate 37, ie in the axial direction of the forme cylinder 33, preferably along several shafts 44 and / or along the pressure forms stacked in one of the shafts 44 37 vertically movable so that the code reader 71 or the mirror detects the coding of stored in different storage positions printing forms 37. Either the code reader 71 or at least one other sensor 91 may be used to monitor and / or to check whether an intended printing plate change has been carried out successfully. Errors such as a double assignment or a faulty assignment, ie the mounting of a printing plate 37 at an incorrect location, are then avoidable, but at least detectable by a preferably deposited on the control station of the printing press message before a greater damage occurs.

6, a further shaft 42 is shown, which serves the recording of the forme cylinder 33 remote printing plates 37. This slot 42 has a z. B. inclined support 72, which as well as the support 54 in the shaft 44 to provide on the forme cylinder 33 to be mounted printing plates 37 is preferably not formed over the entire surface, but in the form of parallel strips 72 or slides 72, wherein the inclination of the support 72 the Shaft 42 preferably expands on the side facing away from the forme cylinder 33, whereby this shaft 42 is more accessible to the operator on the side facing away from the forme cylinder 33, which facilitates the removal of stored in the slot 42 printing plates 37. The support 72 in the shaft 42 is z. B. inclined to a horizontal H by an inclination angle 8, wherein the inclination angle δ z. B. between 5 ° and 15 °, preferably about 7 ° can be. In the example shown in Fig. 6, the chute 42 for receiving printing forme 37 removed from the forme cylinder 33 is located below a chute 44 for providing printing forme 37 to be mounted on the forme cylinder 33, which is a preferred, but not mandatory arrangement. The shafts 42; 44 may also be layered in reverse order or may be separate.

A preferred embodiment of the shaft 42 provides that in the shaft 42 in the axial direction of the forme cylinder 33 next to each other at least two printing plates 37 can be stored. This embodiment allows a particularly rapid removal of printing plates 37, in particular when at least two printing plates 37 can be arranged on the forme cylinder 33 in its axial direction, because a plurality of printing plates 37 can be removed simultaneously from the forme cylinder 33. If on the forme cylinder 33 in its axial direction z. B. at least four printing plates 37 can be arranged, it is advantageous for Stabllitätsgründen, z. B. two shafts 42 in the axial direction of the forme cylinder 33 next to each other. Each defined by the width B of a printing plate 37 storage space in one of these shafts 42 is then formed such that there are at least as many printing plates 37 can be stored as printing plates 37 on the form cylinder 33 can be arranged along its circumference, wherein the storage of the printing plates 37 takes place at each storage space one above the other in a stack. It can be provided that in each of the shafts 42 up to ten, but at least up to eight printing plates 37 can be stored so that discharged from the forme cylinder 33 printing plates 37 can be collected in the shafts 42 and the shafts 42 is not necessarily after each change of the printing plates 37 must be cleared by the operator. Regardless of the number of juxtaposed wells 42, the storage locations in the axial direction of the forme cylinder 33 have the same close spacing from each other as the printing formes 37 are arranged on the forme cylinder 33.

A distance a73 of the guide element 73 from the lateral surface 07 of the forme cylinder 33 is preferably not much greater than the length l14 of the bent-in suspension element 14 at the trailing end 04 of the printing plate 37, in particular the distance a73 of the guide element 73 is between the simple and the double Length I14 of Einhänlegeels 14 on (Fig. 6). Since a printing forme 37 to be removed from the forme cylinder 33 touches the guide element 73 with its printed image side, its contact with a rotatably mounted rolling element 73 is gentler on its surface than sliding on a flat rigid wedge 73. This aspect is of particular importance when the printing form 37 should be used again and thus damage to their printed image page by scratches or marks must be avoided. On the guide member 73, a sensor 91 may be mounted, either in contact with the forme cylinder 33 to be removed from the printing plate 37 or advantageously contactless, z. B. inductive, checks whether the suspension leg 14 at the trailing end 04 of the forme cylinder 33 to removing printing form 37 has actually solved after an actuation of the arranged in the channel 08 of the forme cylinder 33 holding means 21. With its test, the sensor 91 sends a signal z. B. to the press belonging to the control room. On the basis of the signal emitted by the sensor 91, a decision is made as to whether the process of discharging a printing forme 37 to be removed from the forme cylinder 33 can be continued or whether measures for eliminating a malfunction must be initiated. On the guide member 73, preferably a plurality of sensors 91 are provided in the axial direction of the forme cylinder 33, for. B. four or six, namely in each case at least one sensor 91 for each on the forme cylinder 33 in the axial direction next to each other can be arranged printing form 37th

In a preferred exemplary embodiment, the suspension leg 14 at the trailing end 04 of the printing forme 37 to be removed from the forme cylinder 33 preferably passes on a first ramp 74 spaced from the guide element 73 before reaching the support 72 in the shaft 42, wherein the first ramp 74 initially rises in the direction of the support 72 and, after a summit point 76, drops towards the support 72. The first ramp 74 is preferably rigidly connected to the support 72. As the introduction of the forme cylinder 33 to be removed from the printing forme 37 in the slot 42 hits her suspension leg 14 at the trailing end 04 on a second ramp 77, the edge after its peak point 78, ie, on the side facing away from the forme cylinder 33, preferably abruptly steep falls to rest 72 towards. In the direction in which the printing plate 37 is inserted into the shaft 42, at a short distance a77 (FIG. 14) behind the summit point 78, a stop 79 rigidly connected to the second ramp 77 is arranged, to which the suspension leg 14 at the trailing end 04 of the printing plate 37 strikes. The distance a77 in this case has a value of a few millimeters, preferably a value less than the single length 114, in particular less than half the length I14 of the folded Einhängebelt 14 at the trailing end 04 of the printing plate 37. If the Elnhängeschenkel 14 at the trailing end 04 of the printing plate 37 abuts against the stop 79, it preferably engages behind the second ramp 77 by the Elnhängeschenkel 14 engages in the space formed by the distance a77. The second ramp 77 and the stop 79 connected to it are linearly movable by a conveyor 81 and parallel to the support 72 in order to completely convey the printing forme 37 to be removed from the forme cylinder 33 into the shaft 42. The conveyor 81, which forms in particular together with the set edge on the second ramp 77 for the folded suspension leg 14 at the trailing end 04 of the printing plate 37a the printing plate 37 in the slot 42 promoting entrainment is z. B. as a belt drive 81 or as a linear drive 81, preferably as a pneumatic linear drive 81, in particular as a rodless, double-acting linear actuator 81 formed both the first ramp 74 and the second ramp 77 consist z. B. not from full-surface planes, but from several parallel as the tines of a comb arranged guide rails. The second ramp 77 may, for. B. be formed from one or more correspondingly bent metal strip.

On the side facing away from the forme cylinder 33, a lifter 82, in particular a printing form lifter 82 is arranged in the shaft 42, wherein the printing form lifter 82, for example, a preferably perpendicular to the support 72 movable piston 83, at the end of a z. B. L-shaped, in particular U-shaped lifting arm 84 is arranged, wherein the bent suspension leg 14 is set up at the trailing end 04 of the printing plate 37 on the lifting arm 84 or set encompassing. The printing form lifter 82 preferably has two stable operating positions, namely a stable operating position with the piston 83 retracted, in which the lifting arm 84 is below the level defined by the support 72, and another stable operating position with the piston 83 extended, in which the lifting arm 84 All of the forme cylinder 33 remote printing form 37 lifts from the support 72. The printing form lifter 82 performs a stroke s82, which is greater than the length I14 of the folded Einhänbringels 14 at the trailing end 04 of the printing plate 37. Preferably, the stroke s82 has a value between the single and double length I14 of the suspension rack 14. The printing form lifter 82 thus lifts a printing forme 37 removed from the forme cylinder 33 from a provisional first one Storage position in a final second storage position.

Above the printing form lifter 82, in particular above its lifting arm 84, a preferably pivotable about a substantially parallel to the width B of the printing plate 37 extending pivot axis securing element 86 is arranged, for. B. in the form of a strip-like flap 86, whose or the lower edge is located at a distance a86 from the lifting arm 84, wherein the distance a86 is preferably dimensioned smaller than the length of the bent I14 14 hanging 14 at the trailing end 04 of the printing plate 37th In the 6, a directional arrow indicates the pivotability of the securing element 86. The securing element 86 secures a printing form 37 lifted by the printing form lifter 82 against unintentional slippage in the shaft 42 or removal from the shaft 42. Thus, an operator first has to pivot the securing element 86 before the raised printing form 37 can be removed from the shaft 42.

A further exemplary embodiment of assemblies arranged in the shaft 42 is shown in FIGS. 10 to 12. This embodiment provides a preferably rigidly arranged in the central region of the support 72 stop 79, wherein a linearly along the support 72 movable conveyor 81 associated printing form lifter 82 the folded suspension leg 14 at the trailing end 04 of a forme cylinder 33 to be removed printing plate 37 on the Stop 79 raises and the printing forme 37 pulls on its folded suspension leg 14, preferably in its raised state from the printing form lifter 82 state to the side facing away from the forme cylinder 33 end of the shaft 42. The conveyor 81 and the printing form lifter 82 may be positively coupled such that the printing form lifter 82 then lifts the bent suspension leg 14 of the printing plate 37 as soon as the conveying device 81 carries out a movement in the direction away from the forme cylinder 33. Furthermore, a further printing form lifter 87 is provided between the stop 79 and the forme cylinder 33 facing the end of the shaft 42, which raises the leading end 03 of a form cylinder 33 remote, inserted into the slot 42 printing form 37 so far that another from the forme cylinder 33rd to removing printing form 37 between the support 72 and the raised printing plate 37 into the slot 42 is inserted.

In particular, methods for changing printing plates 37 on a forme cylinder 33 will be explained with reference to FIGS. 13 to 35. It is assumed that two printing plates 37 are arranged in the upper shaft 44 for providing new printing forms 37 to be mounted on the forme cylinder 33, that two printing plates 37 are placed on the forme cylinder 33 along its circumference and that the lower shaft 42 is for receiving the Shaping cylinder 33 removed printing plates 37 empty, d. H. is free of printing plates 37.

The forme cylinder 33 rotates the opening 09 of a channel 08, in which the Einhängewonkel 14 is held at the trailing end 04 of the forme cylinder 33 to be removed printing plate 37 by a holding means 21, in a first position, which is below the lower shaft 42 belonging to the guide element 73 is located. The controllable, preferably pneumatically actuable pressure element 24 is set against the forme cylinder 33 (FIG. 13).

The preferably pneumatically actuable actuating means 23 pivots the holding means 21 against the force of a spring element 22, whereby the suspension leg 14 at the trailing end 04 of the printing plate 37 due to its elastic residual stress from the opening 09 snaps and abuts the guide member 73. The employed pressure element 24 secures the printing forme 37 against a further release from the lateral surface 07 of the forme cylinder 33 (FIG. 14).

The forme cylinder 33 rotates counter to its production direction P and pushes the trailing end 04 of the printing forme 37 into the shaft 42. When the printing forme 37 is inserted into the shaft 42, the suspension leg 14 slides along the trailing end 04 of this printing forme 37 along the guide element 73 then adjusts to the first ramp 74 belonging to the shaft 42. The suspension leg 14 slides up the ramp 74 to upper peak 76 and then reaches the support 72nd

While the pressing member 24 is still employed on the forme cylinder 33, the printing forme 37 is pushed further into the slot 42 by the rotation of the forme cylinder 33 counter to its production direction P. In this case, their suspension accessories 14 at the trailing end 04 also overcomes the second ramp 77 connected to the conveying device 81 and abuts against the stop 79 connected to the second ramp 77 (FIG. 15).

The pressing element 24 is turned off by the forme cylinder 33. By the impact of Einhänlegeels 14 of the trailing end 04 on the stopper 79, the preferably positively connected at the front edge 16 of the opening 09 hinged folded Elnhängeschenkel 13 dissolves at the leading end 03 of the printing plate 37 from the. Opening 09. The printing plate 37 is now with its leading end 03 freely on the lateral surface 07 of the forme cylinder 33 auf..Der form cylinder 33 has performed from the loose of the Einhängeschenkeis 14 at the trailing end 04 until now less than half a turn. The folded suspension leg 14 at the trailing end 04 has hooked between the second ramp 77 and the stop 79. The conveying device 81 connected to the second ramp 77 and the stop 79 can now completely draw the printing forme 37 into the slot 42 (FIG. 16).

The pressure plate 37 is removed from the forme cylinder 33 and is in its length L in the shaft 42. Its suspension leg 14 at the trailing end 04 is located on the summit point 78 of the second ramp 77, while their leading end 03 on the summit point 76 of the first ramp 74th rests, whereby at least the suspension leg 13 preferably hangs freely at the leading end 03. The storage of the printing plate 37 in the shaft 42 is thus preferably carried out by a support at two points, namely on the summit points 76; 78 of the two ramps 74; 77 (Figure 17).

The z. B. pneumatically actuated Druckformheber 82 lifts the retracted into the slot 42 printing plate 37 at its trailing end 04 to briefly under the securing element 86, wherein the suspension leg 14 rests on the associated with the printing forme lifter 82 lifting arm 84 (Fig. 18).

While a first to be mounted on the forme cylinder 33 printing forme 37 with its folded Einhänbringeln 13; 14 rests on the support 54 in the upper shaft 44, the forme cylinder 33 continues to rotate counter to its production direction P in a second position until the opening 09, from which the suspension leg 13 at the leading end 03 of the previously removed from the forme cylinder 33 printing plate 37 has been solved has passed a contact point 88 of the pressure element 24 applied to the forme cylinder 33 and the rear edge 17 of the opening 09 in the production direction P of the forme cylinder 33 is at a distance a88 from the contact point 88, the distance a88 being in the range of a few millimeters, preferably is less than 30 mm, and thus corresponds to an arc length of less than a thirtieth part of the circumference of the forme cylinder 33. The first position of the forme cylinder 33 for removing a printing form 37 arranged thereon is i. d. R. not identical to its second position for receiving a new printing form 37. The pressing member 24 is preferably made to the forme cylinder 33, while the opening 09 passes the contact point 88 or after it has passed the contact point 88. The alignment device 51, which is arranged close to the forme cylinder 33, pivots with its previously preferably horizontally oriented diametrical stops 52; 53 preferably by 90 ° in a vertical position, so that a matched to the width B of the forme cylinder 33 to be mounted on the printing plate 37 stop 52; 53 immersed in a defined by the support 54 in the shaft 44 transport plane for the mounted on the forme cylinder 33 printing plate 37 and immersed on the forme cylinder 33 to be mounted printing plate 37 during its transport from the slot 44 to the stop 52; 53 page register moderately aligned to the forme cylinder 33 (Fig. 19).

The first printing forme 37 to be mounted on the forme cylinder 33 rests with its suspension leg 14 at its trailing end 04 on the stop 56 connected to a conveying device 57. The conveyor 57 is put into operation, so that the stop 56 in a direction preferably directed tangentially to the forme cylinder 33 movement the first printing plate 37 so far from the shaft 44, until its leading end 03 touches the Anhaltelement 24 attached to the forme cylinder 33 and the Einhängesrhenkel 13 folded at this leading end 03 between the rear edge 17 of the opening 09 in the production direction P of the forme cylinder 33 and the contact point 88 of the pressure element 24 on the forme cylinder 33 (FIG. 20).

The forme cylinder 33 changes its direction of rotation and begins to rotate in its production direction P, whereby the suspension leg 13 set up on the forme cylinder 33 slips into the opening 09 at the leading end 03 of the printing forme 37 and preferably hooks positively onto the front edge 16 of the opening 09 (Fig. 21).

As a result of the further rotation of the forme cylinder 33 in its product line P, the printing form 37, which is suspended by its suspension leg 13 in the opening 09, is completely conveyed out of the shaft 44 and drawn onto the forme cylinder 33. During winding, the printing forme 37 is rolled onto the forme cylinder 33 by the pressing element 24 placed against the forme cylinder 33. After half a revolution of the forme cylinder 33 in its production direction P, the pressing element 24 presses the folded suspension leg 14 at the trailing end 04 of the printing forme 37 into the opening 09. The retaining means 21 in the channel 08 belonging to this opening 09 has been released and is then inserted into the one Operating position brought in which it introduced into the opening 09 suspension leg 14 at the trailing end 04 of the printing forme 37 z. B. fixed by a clamp. The conveyor 57 moves the stop 56 connected to it back into its end position on the side facing away from the forme cylinder 33 in the shaft 44 (FIG. 22).

The pressure element 24 is turned off by the forme cylinder 33 and the alignment device 51 pivots with its diametrical stops 52; 53 again preferably in a horizontal position. With the method steps described so far, a change of a first printing plate 37 on the forme cylinder 33 is completed by a used printing plate 37 removed and a new printing plate 37 was mounted. This change of a printing plate 37 can with the described device in a very short time, preferably completed in less than a minute. The forme cylinder 33 is then ready for production again (FIG. 23).

The change of another, z. B. on the forme cylinder 33 along its circumference arranged second printing form 37 begins with the fact that preferably during the previous ongoing production of an operator, the new second printing plate 37 is inserted into the slot 44. In this case, the second printing form 37 is held by a controllable, preferably pneumatically controllable printing form holder 58 on the support 54 by the printing forme 37 z. B. either at their ends 03; 04 between two stops 61; 62 is clamped, wherein at least one of the stops 61; 62 is movable, or by the printing plate 37 is inserted at its longitudinal sides in guide rails 64, wherein at least one of the guide rails 64 along the width B of the printing plate 37 is movable. When the printing form holder 58, the printing plate 37 releases by its holding the printing plate 37 elements, for. B. the stops 61; 62 or the guide rails 64, their distance, z. B. a58, each other at least briefly increase, the printing plate 37 falls on the support 54 and is there with their Einhänbringeln 13; 14 (FIG. 24).

B. the second printing form 37 from the forme cylinder 33, rotates the forme cylinder 33 according to the method explained for Fig. 13, the opening 09 of the channel 08, in which the suspension leg 14 at the trailing end 04 of the forme cylinder 33 to be removed second printing form 37 of a holding means 21 is held, in the first position, which is located below the lower shaft 42 belonging to guide member 73. The controllable, preferably pneumatically actuated pressure element 24 is set against the forme cylinder 33 (FIG. 25).

According to the method explained with reference to FIG. 14, the preferably pneumatically actuable actuating means 23 pivots the holding means 21 against the force of the spring element 22, whereby the suspension leg 14 on the trailing end 04 of the second printing form 37 snaps out of the opening 09 due to its elastic residual stress and on the guide element 73 strikes. The employed pressure element 24 secures the second printing plate 37 against further release of the lateral surface 07 of the forme cylinder 33 (FIG. 26).

The forme cylinder 33 rotates counter to its production direction P and thereby pushes the trailing end 04 of the second printing form 37 into the shaft 42. When the printing forme 37 is inserted into the shaft 42, the suspension leg 14 first slides along the trailing end 04 of this printing plate 37 along the guide element 73 and then positions itself on the first ramp 74 belonging to the shaft 42. The suspension leg 14 of the second printing form 37 slides up the ramp 74, where it slides under the resting in the shaft 42, resting on the summit point 76 of the first ramp 74 first printing plate 37 and its at. Summit point 76 overhanging, directed to the forme cylinder 33 leading end 03 lifts, while the suspension leg 14 of the second printing form 37 exceeds the summit point 76 of the first ramp 74 and then reaches the support 72. While the pressing member 24 is still employed on the forme cylinder 33, the second printing forme 37 is pushed further into the slot 42 by the rotation of the forme cylinder 33 counter to its production direction P. In the process, the suspension leg 13 slides at the leading end 03 of the first printing form 37 resting in the shaft 42 over the printed image side of the second printing form 37 fed into the shaft 42. In the further course, the suspension leg 14 at the trailing end 04 of the second printing form 37 also overcomes the one with the conveying device 81 connected second ramp 77 and abuts against the stop associated with the second ramp 77 79 (Fig. 27).
