The invention has for its object to provide a printing machine for securities printing with an Orlof offset printing unit and a method for changing a printing form and for receiving a production.

The object is achieved by the features of claim 1 and 14, respectively.

The achievable with the present invention consist in particular that the printing press, in particular designed as a security printing machine with an Orlof offset printing press despite complex structure effectively and safe to operate and / or operable.

In a preferred embodiment of an Orlof offset printing unit with separable component racks for ink collecting and transfer cylinders, there are advantages, in particular, that the printing press, in particular the printing machine designed as a security printing press with an Orlof offset printing unit, despite its complex structure for washing, Assembly or maintenance purposes more accessible and / or modular executable or expandable.

This triggers a printing machine for the security printing with the features of claim 1 with an Orlof offset printing unit comprising a plurality of stencil cylinders, each of which can be colored by an associated inking unit, a color collecting cylinder cooperating with the plurality of stencil cylinders, an Orlof cooperating with the ink collecting cylinder Plate cylinder, a cooperating with the Orlof plate cylinder transfer cylinder and the transfer cylinder forming a pressure point counter-pressure cylinder achieved in that at least in pressure-An with the Orlof plate cylinder cooperating transfer cylinder through a first printing unit section comprises and in or on a first Partial frame is mounted, the color collection cylinder comprises by a second printing unit section and is mounted in or on a different from the first subframe second subframe, and that the first and the second subframe optionally in a first, a working position forming relative position and in a second, a maintenance position forming relative position are related to each other, being formed in the maintenance position between the first and the second printing unit section and / or between the first and the second subframe, a space that at least a direct access granted to Farbsammelzylinder, the Orlof plate cylinder and to the Orlof plate cylinder cooperating transfer cylinder.

When changing a printing forme on an Orlof plate cylinder, an Orlof offset printing unit arranged in a printing machine for printing is preferred and for receiving a production, a coupling, in particular locking, between a first subframe comprising the Orlof plate cylinder and a standstill of the printing press a second subframe comprising a color collecting cylinder dissolved, with dissolved coupling, in particular locking, the first and the second subframe by activation of a drive from a first relative position, ie one Working position, in a second relative position, ie a maintenance position spent, in which they are further spaced apart and form an accessible space between them, the bare or the free of any form of pressure from the last production on the space Orlof plate cylinder with at least one printing plate equipped for the upcoming production, after loading the first and the second subframe by activation of the same or another drive from the maintenance again spent in the working position to each other, the coupling, in particular locking, between the first and second sub-frame restored, and to this immediately or spaced then made a start of the machine.

The said separability or the o. G. Switching further features, as set forth below and / or based on the embodiments may be added to form an advantageous development individually or in addition to several.

In an advantageous embodiment of the co-acting with the transfer cylinder in impression-on impression cylinder by the first printing unit section and stored in or on the first subframe and / or may include the plurality of stencil cylinders through the second printing unit section and in or on the from stored first subframe different second subframe and / or the Orlof plate cylinder mitumfasst from the first printing unit section and be stored in or on the first subframe.

By separating the machine frame or the printing unit in the compactor between ink collecting cylinder and Orlof plate cylinder and - as far as the arrangement is concerned - spatially between the ink collecting cylinder and transfer cylinder and their relative Lagerveränderlichkeit are color collecting cylinder and transfer cylinder for setup or maintenance work, eg.

In addition, or instead, there may be particular advantages in a forced-tracking embodiment, where the risk of misprints and / or waste may be significantly and comfortably reduced.

This is achieved in particular by the fact that when placing bodies of revolution of a printing press with three in a Anstelllage pairs acting together color-guiding bodies of revolution, with a second, ie, for example, as a middle, the three rotation body to form a two-sided Anstelllage both to a first of the three rotation body is also made to a third of the three rotational body, simultaneously with a radial bearing change of the axis of rotation of the first body of rotation coupled in a defined manner tracking the axis of rotation of the second body of revolution by superposition of two movements along two non-congruent, running in a direction perpendicular to the axis of rotation plane of movement takes place. In particular, a second, ie, for example, mounted between the first and third rotary body in one or more parts frame, the three rotary body mounted so radially movable in a one- or multi-part frame, that he can be brought into a Anstelllage optionally in which he to the first Rotary body and the third rotary body is employed, or in one Abstelllage, in which it is turned off by at least one of the other two rotation body, wherein for supporting the second rotation body frontally a bearing device is provided, which comprises two adjusting elements for radial movement of the second body of revolution by superposition of two non-congruent movements, each with a radial movement component. In this case, a forced dual tracking of the second rotary body is provided, which comprises a coupling of a movement of the two adjusting elements to a radial movement of the first rotating body in a defined manner, so that a radial movement of the first rotating body to a travel greater than zero at the same time a forced readjustment of the two first rotational body positioning actuators each causes a defined travel greater than zero.

The said tracking or said tracking further-forming features, as set forth below and / or based on the embodiments, may be added to form an advantageous development individually or in addition to several.

In one embodiment, the superposition of the two movements by a simultaneous adjustment of a first, in particular designed as a first eccentric actuator and a second, in particular designed as a second eccentric actuator can be done.

It may be provided for coupling with the actuators acting together actuating mechanism by which the adjustment of the two actuating elements with respect to their movement in an embodiment mechanically or in another embodiment via electronic control means coupled to a radial movement of the first body rotation causing the actuating mechanism or a bodies is.

In an advantageous development with a forced double tracking of the Orlof plate cylinder, it is possible after a brief interruptions misprints faulty or incomplete coloring, especially in connection with printing on securities. On the one hand, an increased level of print quality is placed on the security printing, on the other hand, for reasons of cost of the printing material and / or because of the limited and monitored number of sheets as possible any waste can be avoided. Here production interruptions can occur to a greater extent than with the printing of less sensitive products. Thus, for example, in the event of disturbed or already slightly faulty sheet feed, production can be interrupted by the printer or a monitoring device. To after the interruption, however, as little as possible, preferably no waste due to misprints, for example, from faulty z. For example, if incomplete inking of cylinders and / or rollers may result, the rollers and cylinders should be properly colored when the printing process resumes. This is made possible, for example, by a double forced tracking.

In another development of this second alternative, instead of or in addition to this, the subframe attachment 121.3 may be arranged and / or connected to the second subframe 47.2 such that it is operatively along a guide 124 in a direction to the subframe attachment carrying the forme cylinder 115 121.1; 121.1, 121.2 is movable towards and away from it. As a result, a wait or prepare the additional printing unit 28 is possible without having to spend at the same time the underlying printing unit 26 in the maintenance situation.

In an advantageous variant of the above-mentioned first alternative embodiment Fig. 6 can the frame attachment 121.2; 121.3 on the subframe 47.2 in two parts and be formed divisible between the at least one inking unit 119 and the at least one forme cylinder 115 in the above sense for setup purposes. The at least one inking unit 119 is in this case mounted in a frame part attachment 121.3, which is fixedly connected to the at least one inking cylinder 115 to be inked by a second subframe 47.2. 105 supporting frame part attachment 121.2 swiveling or z. B. in the manner of an inking cart on a guide 124 can be moved off.

In the context of Fig. 6 and Fig. 7 For example, likewise not shown means are provided, by means of which the two single or multi-part subframe attachments 121.1, 121.2; 121.3 connect or couple at their point of separation in working position. In working position of a one or more parts, the at least one inking unit 119 supporting subframe attachment 121.3; 121.3, 121.2 of the subframe attachment 121.1 connected to the first subframe 47.1; 121.1, 121.2 turned off and / or unconnected with this. Advantageously, a mechanical locking is provided for coupling, which can be opened and closed remotely operated or remotely operable by at least one actuator. Preferably, the additional printing unit 28 is then formed at the respective separation point together with the Orlof printing unit 26 - divisible with open coupling or connection. With dissolved coupling, in particular Lock, the two subframe attachments are then z.

For the monitoring of the working position and / or the state of the locking can advantageously be provided with said control device in signal connection standing sensors.

When changing a printing plate 25 on the Orlof plate cylinder 22 is at standstill of the printing machine, first, the lock between the first and second sub-frame 47.1; 47.2, in particular by a remote-controlled actuator by the machine control or a control routine implemented in this and / or triggered on an associated with this user interface, z. B. a, control room, solved. When the lock is released, the first and the second subframe 47.1; 47.2 z. B. spent by activating a drive via, for example, a corresponding control routine whose relative position from the working position to the maintenance position in which they are further spaced apart and form the accessible by operating room 05 between them. This is preferably done by moving the second subframe 47.2 at raumfestem first subframe 47.1. The already empty or in a further operation now on the space 05 of any printing plate 25 from a possibly previous last production freed Orlof plate cylinder 22 is then populated with at least one printing for the upcoming production. After loading, the first and the second subframe 47.1; 47.2 spent by activation of the same or another drive via the control routine from the maintenance back to the working position to each other, the lock between the first and second subframe 47.1; 47.2 made, and finally made via a machine control, for example, triggered by a command on the operator interface, a start of the machine. The start is, however, by the machine control in response to a signal state of a working position of the sub-frames 47.1; 47.2, in particular the second subframe 47.2 and / or the state of the locking monitoring sensor performed or prevented in the negative result of the review of working position and / or locking.

In the present case, a second printing unit 27 designed for indirect high-pressure, the fourth printing unit section accommodated in the fourth subframe 47.4 can comprise the inking units 43 of the second printing unit 27, which in the working position of the fourth printing unit section or subframe 47.4 with the z. B. in the main frame 47.1 mounted form cylinders 42 cooperate.

The third and the fourth sub-frame 47.3 47.4 can - except for possibly only slight differences and a mirror-inverted vertical arrangement - structurally, in particular as regards the design and / or arrangement of the storage to be carried out in the same way. Also, the arrangement and the execution of the storage of the inking units 31; 43 cooperating, in the second and in the first sub-frame 47.2; 47.1 arranged cylinder 24; 42, z. B. stencil cylinder 24 on the one hand and forme cylinder 24 on the other hand, in - except for possibly only slight differences and a mirror-inverted arrangement - the same way in or on the respective sub-frame 47.2; 47.1 be provided.

In the first designed as Orlof printing unit 26 printing unit 26 of the form of cylinder 22 formed second cylinder 22 is arranged or stored by means of a bearing device 46 in or on one or more parts frame 47 (47.1) of the printing unit 03, so that it as a middle cylinder 22nd optionally z. B. in pressure-An in an Anstelllage, in particular a double or two-sided Anstelllage, can be brought, in which it is employed on the cylinder 21 designed as a transfer cylinder 21 and designed as a color collection cylinder 23 third cylinder 23 (see, eg. Fig. 7a ), or z. B. at pressure-Ab in a storage position, in which he at least one of the two cylinders 21; 23, but preferably both upstream and downstream downstream cylinder 21; 23, is turned off (see, eg. Fig. 7b ). In storage position, the distances a; b between the effective lateral surfaces of the cooperating cylinder 23; 22; 21 in a same, for the distance a between the pressure-Ab located in color collection and Orlof plate cylinders 23; 22 above range, or even different size ranges and / or be adjustable within the area concerned. In Abstelllage the color transfer from the upstream third to the downstream first cylinder 23; 21 thus interrupted at least one point, closed continuously in Anstelllage.

At least one of the two cylinders 21 cooperating with the second or middle cylinder 22; 23, preferably the downstream, at the formation of the pressure point 12; 13 participating and z. B. as a transfer cylinder 21 formed cylinder 21 is about a correspondingly formed bearing means 48 with respect. Its axis of rotation radially adjustable (see, eg. Fig. 3 and Fig. 4 ). He is z. B. at least in terms of its distance to the other, z. B. with the first cylinder 19 in pressure to the pressure point 12; 13 forming cylinder 19, in particular impression cylinder 19, formed changeable. The other of the two cylinder 23 adjacent to the forme cylinder 22; 21, z. B. the upstream color collecting cylinder 23, is respect. Its axis of rotation, for example, operationally fixed in space fixed in the printing unit 01, but may be out of order, z. B. during commissioning or maintenance, be arranged radially adjustable.

The bearing device 46 of the middle, in particular as a forme cylinder 22, preferably as Orlof plate cylinder 22, formed cylinder 22 is now designed such that the cylinder 22 and its axis of rotation R22 by two superposed movements along two trajectories, ie for example within a rotation axis R22 vertical plane with two degrees of freedom, is movable. This can basically by superposition of two movements along any non-congruent trajectories, eg. B. by superposition of two Linear movements along two non-parallel, but advantageously in a same, preferably to the rotation axis R22 perpendicular plane extending lines or by superposition of two pivoting movements about two spaced apart, but advantageously to each other and preferably also to the axis of rotation R22 parallel pivot axes S1; S2 or by a mixed form of a above-mentioned linear movement and a pivoting movement.

The movement of the cylinder 22 or its axis of rotation R22 in the two degrees of freedom is effected by placing a first and a second control element 49; 51, which in principle can be designed as a linearly movable brackets or swivel lever. In a preferred embodiment, the adjusting elements 49; 51, however, as shown by pivotable eccentric rings 49; 51 of a z. B. formed as a Mehrfachexzenterlager 52 Mehrringlagers 52, z. B. a four-ring bearing 52, formed (see, for. Fig. 4 and Fig. 5 ). The bearing device 46 thus comprises the multi-ring bearing 52 and its connection in or on the frame 47 (see, for example, FIG. Fig. 5 ). A first, inner eccentric ring 49 encloses for example via bearing means 53, z. B. a radial bearing 53, a pin 54 of the cylinder 22 receiving inner ring 56 and in turn, for example, via bearing means 57, z. B. radial bearing 57, surrounded by the second, outer eccentric ring 51. This is in turn for example via bearing means 58 in an outer ring 59 of the multi-ring bearing 52, and the latter received in a bore of the frame 47 and possibly secured against rotation. The eccentric rings 49; 51 are here in a known manner against each other and against the outer ring 59 rotatable, being characterized by the superposition of the eccentricities e1; e2 caused curved paths a two-dimensional radial positioning of the axis of rotation R22 is made possible at least in a limited area control range greater than zero within a plane perpendicular to the axis of rotation R22 level.

The radial positioning or movement of the cylinder 21 designed as a transfer cylinder 21 or its axis of rotation R21 in the radial direction can be achieved by placing only an actuating element 61, which can basically be embodied as a linearly movable holder or as a pivotable lever, take place (see, for example, FIG. Fig. 4 ). In a preferred embodiment, the in Fig. 6 by a setting disc 55 partially hidden actuator 61 by a pivotable eccentric ring of a z. B. designed as an eccentric multi-ring bearing, z. B. a three-ring bearing formed. The bearing device 48 in this case thus comprises the multi-ring bearing not shown in detail and its connection in or on one or more parts frame 47 of the printing unit 03. An unillustrated inner eccentric encloses this case via bearing means a journal 62 of the cylinder 21 receiving radial bearings and in turn, for example, via bearing means, received in an outer ring of the multi-ring bearing, and the latter in a bore of the frame 47 and possibly secured against rotation. The eccentric ring is in this case rotatable in a known manner against the outer ring, wherein a radial positioning of the axis of rotation R21 along a curved path is made possible by the eccentricity, not shown in the figure, which extends in a direction perpendicular to the axis of rotation R21 plane.

B. a single or multiple lever mechanism 66; 67, for example, one with the respective eccentric ring 49; 51 connected tab 78; 79 on. In the example, the respective transmission 66 comprises; 67 a two-armed lever, which about a pivot axis S68; S69 is pivotable. The two-armed lever is z. B. by two on a same shaft 68; 69 rotationally arranged lever arms formed, wherein the respective shaft 68; 69 can connect two drive mechanisms for two end bearing arrangements of the cylinder 22 as a synchronous shaft. In the example, the output side lever arm is not directly, but via a rocker 85; 95 with the eccentric ring 49; 51 and the eccentric ring-fixed tab 78; 79 connected.

In principle, the actuator 63; 64 itself and / or the gear 66; 67 with respect to its travel adjustable or at least be adjustable, and thus make a Wegbegrenzung for the adjusting movement possibly superfluous (see, for example, below to Fig. 9 ).

In a first, advantageous embodiment, the adjusting movement of the cylinder 22 and the adjusting elements 49 takes place; 51 at least in Anstellrichtung, ie in the direction of the respective Anstelllage, but in each case against a stop limiting the stop 71; 72. This stop 71; 72 can in the region of the actuator 63; 64 itself, in the gearbox 66; 67 or with the actuator 49; 51, ie the eccentric ring 49; 51, or one with the actuator 49; 51 connected counter-attack 73; 74, be arranged cooperatively. The respective stop 71; 72 is in a preferred embodiment here with an eccentric ring-fixed counter-stop 73; 74, z. B. a stop surface 73; 74 one with the respective eccentric ring 49; 51 firmly connected tab 76; 77 or nose 76; 77 formed. The respective drive mechanism, for. B. the output-side end of the transmission 66; 67, can directly on the respective eccentric ring 49; 51, on which the stop surface 73; 74 comprehensive tab 76; 77 or for reasons of space on another, z. B. in the circumferential direction of the eccentric ring 49; 51 by more than 90 ° spaced tab 78; 79, attack. The tabs 76; 77; 78; 79 are in the illustrated embodiment with with the eccentric rings 49; 51 firmly connected, the eccentric rings 49; 51 in the representation concealing adjusting discs 65; 75 or collars 65; 75 connected (see eg Fig. 4 ).

Upon actuation of the first and the second actuator 63; 64 each in a hiring effecting direction r1; r2 will now, z. B. via the relevant gear 66; 67, the associated eccentric ring 49; 51 twisted until it with its stop surface 73; 74 to the stop surface of the associated stop 71; 72 runs up. The location of the first and second eccentricity e1; e2 is selected such that the second cylinder 22 is turned on to the first cylinder 21 and the third cylinder 23. About the position of the stop 71; 72 in the circumferential direction of the eccentric ring 49; 51 is considered the end position, ie the respective Anstelllage defined. This position of the stops 71; 72 can for adjusting the Anstelllage, ie the pressure between the cylinders 19; 22; 23, be designed adjustable (see below). To one through the actuators 63; 64 each applied force for the stops 71; 72 to limit and / or even when adjusting the relevant stop 71; 72 striking with the counter-stop 73; 74 to ensure pressure on or Anstelllage, the transmission 66; 67 with regard to a power transmission, at least as regards the force in the direction of Anstelllage be sprung trained. The transmission 66; 67 may be resilient in nature, so that when hiring the eccentric stop 73; 74 to the stop 71; 72 with a travel of the actuator 63; 64, which is greater than one for the employment of the stops 71; 72; 73; 74 required travel, at least slight compression of the transmission 66; 67 takes place. For this purpose, a pivot axis S68; S69 or an input or output side hinge of the lever or a joint of the rocker 85; 95 against a spring force movable in or on the cooperating lever arm or be mounted on the cooperating coupling.

The three z. B. as a transfer cylinder 21, as a form cylinder 22 and as a color collection cylinder 23 formed cylinder 21; 22; 23 are so mounted in one or more parts frame 47 that the downstream of the three cylinders 21 in its distance to the z. B. is designed as a counter-pressure cylinder 19 further cylinder 19 is changeable, and that the middle of the three cylinders 22 both in its distance from the downstream adjacent cylinder 21, as well as in its distance to the upstream adjacent, z. B. operatively fixed space arranged cylinder 23, adjustable, in particular to these on and off this is stored, is stored.

Now, if the radial position of the first, designed in particular as a transfer cylinder 21 cylinder 21 is changed in such a way that the distance between this and the second cylinder located in Anstelllage changed 22, the pressure resulting in Anstelllage deviates from the desired. By the solution set forth below, it is now possible, the distance between the axes of rotation R21; R22; R23 and thus the pressure between the three cylinders even with radial position change, in particular even during this change in position, the first of the three arranged in series cylinder 22 is substantially constant, d. H. within a tolerance range for the distance.

Here is a positively coupled tracking of the middle of the three cylinders 21; 22; 23 provided such that a radial movement of the downstream adjacent, z. B. as a transfer cylinder 21 formed cylinder 21 to a travel greater than zero within its operating range a forced setting of the two central cylinder 22 with respect. Two radial directions positioning actuators 49; 51 causes a defined travel greater than zero. The forced location is hereby dimensioned and arranged such that a distance of the axis of rotation R22 of the Anstelllage to the upstream and the downstream cylinder 23; 21, to both the axis of rotation R23 of the upstream cylinder 23 and its distance from the axis of rotation of the downstream cylinder 21 when the position of the downstream cylinder 21 changes substantially within its operating range, ie less than, for example, when within the operating range one fiftieth, in particular less than a hundredth, of the radius of the middle cylinder 07 varies (see eg Fig. 6 and Fig. 7 ). In the Fig. 6 and Fig. 7 was the in Fig. 4 set forth drive mechanism for switching on / off for reasons of clarity not shown, but only indicated by dashed lines. Here are parts of the drive mechanism for on / off and for tracking on the same Attack tab 78 and depending on the view at least partially obscured.

The forced in tracking positions of the two the middle of the three cylinders 22 positioning actuators 49; 51, if necessary, by appropriate control of the actuators 63; 64, if they are designed to be controllable with respect to their positioning within their travel. Preferably, however, the positioning coupled to the movement of the first cylinder 21 is effected by a forced change in position of the stop 71 limiting the movement for the setting-up position; 72 at least one of the adjusting elements 49; 51, preferably both adjusting elements 49; 51. As a result, the Anstelllage of the second cylinder 22 with respect to the two adjacent cylinders 21; 23 coupled to the position of the first cylinder 21 defined, and changed in a change in position of the first cylinder 21 forcibly and in a defined manner.

The enforced in tracking bodies, ie readjustment of the two of the middle of the three cylinders 22 positioning actuators 49; 51 may in a first embodiment by mechanical means, in particular by purely mechanical means, take place (see, eg. Fig. 6 and Fig. 7 ).

Here are the double tracking of the second cylinder 22, ie the two adjusting elements 49; 51, the Anstelllage for the adjusting elements 49; 51 delimiting stops 71; 72 movably mounted and with respect to their movement mechanically to the adjusting mechanism 48, 55; 61, 81 of the first cylinder 21, z. B. to the partially hidden actuator 61, z. B. the eccentric ring 61, or as shown on the adjusting ring 55 and the adjusting disc 55 or to the actuator 61 driving the drive mechanism 81 coupled. The mechanical coupling can basically parallel to the two stops 71; 72, or as shown for an advantageous embodiment serially initially medium or directly on one of the two movable stops 71; 72 and from this via the movement of the associated actuating element 49; 51 middle or directly on the other of the two stops 72; 71 done. The drive of the first of the two stops 71 via a first, an adjusting movement of the first cylinder 21 and its actuator in a movement of the first stop 71 transforming gear 91, z. B. a lever mechanism 91. This is done for example via a coupling 82, whose one end on the actuator 61, z. B. eccentric 61, the first cylinder 21, in particular at one with this z. B. via the collar 65 connected tab 83, engages and their output-side end on a stop 71 comprehensive lever 84 engages. The lever 84 is pivotally mounted about a pivot axis S84 and includes on a counter stop 73 side facing the stop 71. This stop 71 is formed on the counter stop 73 side facing by a cam segment 88 such that pivoting of the lever 84 has a defined variation a contact point between stop 71 and eccentric ring-fixed counter-stop 73 in the circumferential direction of the eccentric ring 49 has the consequence. The drive mechanism, the arrangement and design of the lever and the cam segment 88 is such that the placement of the first cylinder 21 in a certain direction a defined locations of the first actuating element 49, z. B. first eccentric ring 49, in a certain direction, and thus causes a defined first of the two to superponierenden movements of the cylinder 22 and the axis of rotation R22.

The drive of the second of the two serially driven stops 72 is effected by the movement of the first actuator 49, ie the first eccentric ring 49, via a rotary movement of the first eccentric ring 49 in a movement of the second stop 72 reshaping gear 92. For this purpose, one on the first Eccentric ring 49 or at one of its tabs 76; 78 hinged coupling 86 medium or act directly on the second stop 51. In an advantageous embodiment, the acts with the first eccentric ring 49, z. B. with respect to the outer circumference eccentrically coupled coupling 86 via a single or multi-stage gear 92, z. B. single or multi-stage lever mechanism 92, on a lever 87 is pivotable about the coupling with the first eccentric ring 49 by turning the eccentric ring 49 about a pivot axis S87 and includes the second stop 72 on a side facing the second counter-stop 74 side. This stop 72 is also formed on the counter-stop 74 side facing by a curve segment 89 such that pivoting of the lever 87 again has a defined variation of a contact point between the second stop 72 and eccentric ring-fixed counter-stop 74 in the circumferential direction of the second eccentric 51 result. The drive mechanism, the arrangement and design of the second lever 87 and the cam segment 89 is such that the placement of the first cylinder 21 in a certain direction over the movement of the first actuating element 49 a defined locations of the second control element 51, z. B. the second eccentric ring 51, in a certain direction, and thus a defined second of the two to superponierenden movements of the cylinder 22 and the axis of rotation R22 causes. In here advantageously two-stage lever mechanism 92 cooperating with the second eccentric ring 51 coupling 86 acts on a pivotable about a pivot axis S93 lever 93. For pivotal mounting of the lever 93 may be disposed on any fixed shaft or shaft axis, but here z. B. rotatably mounted on the existing shaft 68. The lever 93 may in particular be single-acting or possibly two-armed, but is preferably designed to translate the movement of the eccentric ring 51 in the region of the coupling into an enlarged movement of the driven-side end. The output-side end of the lever 93 can either act directly on the second lever 87 to move it, but here in an advantageous embodiment via a rocker 94 (see, eg. Fig. 7 ) hingedly connected to the lever 87.

B. a frame fixedly mounted stop roller 98; 99, is arranged such that a guided relative movement with only one degree of freedom in the longitudinal direction of the recess 96; 97 is enabled. The axis of the stop roller 98; 99 falls here with the effective pivot axis S84; S87 of the lever 84; 87 together. The stop rollers 98; 99 do not rotate, but can also be used as non-rotatably arranged stop disks 98; 99 be formed. The position of the relative position between stop 98; 99 and lever 84; 87 takes place for example by an adjusting disk 101; 102 with helically varying outer circumferential line, z. B. a screw 101; 102, whose outer periphery with a lever-fixed stop 103; 104 works together. The screw 101; 102, for example, on the stop roller 98; Supported bearing shaft 99 and acts to avoid friction with a roller 103; 104 formed lift-resistant stop 103; 104 together. The screw 101; 102 is medium or directly by a drive mechanism, not shown, for. B. a handwheel or a motor drive, adjustable. By turning the adjusting disk 101; 102, the lever-fixed stop 103; 104 and thus the lever moves in the direction of the degree of freedom. The setting by the adjusting disk 101; 102 takes place here preferably against the force of a spring element 106; 107, z. B. a tension spring 106; 107, so that a fixed system between adjusting disc 101; 102 and impact-resistant stop 103; 104 is guaranteed. Instead of the movable stop surface on the effective as an actuator adjusting disc 101; 102 and the biasing by spring force is basically a two-sided effective coupling between an actuator and the lever 84; 87 conceivable.
