B. a designed as a plate cylinder 07 form cylinder 07, a plate cylinder 07 associated dampening unit 08 and the plate cylinder 07 associated inking 09. The dampening 08 can be, for example, brush dampenings, film dampenings or spray dampening. In each case two plate cylinders 07 are arranged at least substantially horizontally next to each other. In each case two plate cylinders 07 are arranged one above the other at least substantially in the vertical direction. The same applies to the transfer cylinder 06, whose axes define at least approximately a square.

Between the two upper printing units 21; 22 or the transfer cylinders 06 is a guide roller 19 is arranged such that a guided through the nine-cylinder satellite printing unit 16 Bedruckstoff- or paper web 23 is not deducted from the transfer cylinders 06, d. H. This does not wrap around, which is essential for the possibility of using an imprinter.

The plate cylinders 07 of the printing units 03; 04; 21; 22 is associated with a plate changing device 11 in order to automate the laying of printing plates on the respective plate cylinder 07 and accelerate. The plate changing devices 11 may be those which are explained in more detail below. For each printing unit 03; 04; 21; 22, the arrangement is such that both the associated inking unit 09 and the associated dampening unit 08 are arranged below an upper area of the respective plate cylinder 07 in order to make room for the above the respective inking unit 09 arranged plate changing device 11th

The satellite cylinder 18 may preferably have its own position-controlled drive motor 12. In this drive concept, a plate change on a plate cylinder 07 can be carried out independently of a plate change on another plate cylinder 07th

The upper nine-cylinder satellite pressure unit 17 corresponds in structure to the lower nine-cylinder satellite pressure unit 16. The upper nine-cylinder satellite pressure unit 17 thus again comprises a serving as a satellite cylinder 18 impression cylinder 18 and four arranged thereon printing units 28; 29; 31; 32. For a detailed description, reference may therefore be made to the above. In particular, therefore, the arrangement of the printing units 03; 04; 21; 22 or cylinder 06; 07; 18 of a printing unit 16 according to the arrangement of the printing units 28; 29; 31; 32 or cylinder 06; 07; 18 of the other printing unit 17.

As from the in Fig. 1 each indicated by an arrow directions of rotation of the cylinder 06; 07; 18 in production, so in printing operation is clear, rotate the plate cylinder 07 a nine-cylinder satellite printing unit 16 or 17 in the printing operation by design, all in the same direction. For mounting an elevator 101, z. B. a printing plate 101 (see. Fig. 3 ) on a plate cylinder 07, the direction of rotation of the plate cylinder 07 must always point in the direction in which the pressure plate 101 is fed to the plate cylinder 07. In this respect, the in Fig. 1 registered directions of rotation of the plate cylinder 07 of the printing units 03; 21; 29 and 32 coincide with the direction of rotation of the winding, but not the directions of rotation of the plate cylinder 07 of the other printing units 04; 22; 28 and 31. To solve this problem, it is provided according to the invention that for these printing units 04; 22; 28 and 31, the respective printed image is applied in a rotated by 180 ° orientation on the printing plates 101 and that in the plate cylinders 07 of these printing units 04; 22; 28 and 31, the direction of rotation when mounting the printing plates 101 is reversed, as in Fig. 2 is indicated. After mounting the corresponding printing plates 101, the direction of rotation of these plate cylinder 07 of the printing units 04; 22; 28 and 31 again turn back, so they are now back in the printing direction according to Fig. 1 move, but now with the usually trailing ends of the printing plates 101 now leading. This will be explained in more detail below.

Fig. 3 shows an embodiment of a plate-shaped pressure plate 101 made of elastically flexible metal. It may, for example, have a length L between 400 mm and 1,300 mm and a width B between 280 mm and 1,500 mm. Over a Support surface 102, the pressure plate 101 is in the mounted state on the lateral surface of a plate cylinder 07. The pressure plate 101 has two opposite ends 103; 104 with angled Einhänbringeln 113; 114, wherein the leading suspension leg 113 of a first, leading end 103 is angled, for example, acute angle and the trailing suspension leg 114 of a second, trailing end 104, for example, at right angles.

At the leading end 103 of the suspension leg 113 is preferably acute-angled, in particular in an opening angle of 35 ° to 55 ° and at the trailing end 104 of the suspension leg 114 is preferably angled in an opening angle of 80 ° to 100 °.

B. cylinder channel 108 is arranged, which extends within the plate cylinder 07 id R. in the axial direction to the plate cylinder 07. The rectified with the production direction P of the plate cylinder 07 end 103 of the pressure plate 101 is referred to as the leading or first end 103, whereas the opposite end 104 is referred to as trailing or second end 104 of the pressure plate 101.

The suspension legs 113; 114 are inserted into a narrow, in particular slot-shaped opening 109 of the channel 108 of the cylinder 07 and there by means of the holding device 119, z. B. a clamping device fastened.

The acute angle beveled suspension leg 113 at the leading end 103 of the pressure plate 101 is at the front edge 116, z. B. suspension edge 116 of the opening 109 can be positively locked and the right angle beveled suspension leg 114 at the trailing end 104 of the pressure plate 101 is at the rear edge 117 of the opening 109 can be suspended in a form-fitting manner.

In the channel 108 are z. B. at least one pivotally mounted holding means 121 and a biased spring element 122 is arranged, wherein the spring element 122, the holding means 121 z. B. presses against the folded suspension leg 114 at the trailing end 104 which is hooked to the opening 109 at its rear edge 117, whereby the suspension leg 114 is held at the trailing end 104 at the extending from the rear edge 117 to the channel 108 toward wall , To release the pressure exerted by the holding means 121 pressing an adjusting means 123, preferably a pneumatically actuable adjusting means 123 is provided in the channel 108, which pivots the holding means 121 against the force of the spring element 122 and releases the suspension leg 114 in its operation. The holding device 119 described, for example, consists essentially of the holding means 121, the spring element 122 and the adjusting means 123.

In the Fig. 4 shown orientation of the arrangement applies in the case of Fig. 1 shown printing tower 14 on the plate cylinder 07 of the printing units 03; 21; 29 and 32, while the orientation in the case of the printing units 04; 22; 28 and 31 is a mirror image. In other words, the above-mentioned mirror image configuration of the nine-cylinder satellite pressure unit 16 or 17 or the pressure tower 14 formed thereby is given about a vertical center plane M also with regard to the configuration of the channels 108 in the respective plate cylinders 07.

The slider 159 of the printing plate holder 158 is preferably linearly parallel to the support 154 movable and preferably has two stable operating positions, namely a stable operating position in the retracted, the second pressure plate 101 releasing state and in the extended, d. H. the second pressure plate 101 chucking state.

In the Fig. 9 a further shaft 141 is shown which serves to receive printing plates 101 remote from the plate cylinder 07. This shaft 141 has a z. B. inclined support 172, which as well as the support 154 in the shaft 143 to provide on the plate cylinder 07 to be mounted pressure plates 101st preferably not over the entire surface, but in the form of parallel strips 172 or slide rails 172 is formed. In the in the Fig. 9 As shown, the tray 141 for receiving the plate cylinder 07 remote printing plates 101 below the shaft 143 for providing to be mounted on the plate cylinder 07 printing plates 101, which is a preferred, but not mandatory arrangement.

A preferred embodiment of the duct 141 provides that at least two pressure plates 101 can be stored next to one another in the shaft 141 in the axial direction of the pressure cylinder 07. This embodiment allows a particularly rapid removal of printing plates 101, in particular when at least two printing plates 101 can be arranged on the plate cylinder 07 in its axial direction 101, because a plurality of printing plates 101 can be removed simultaneously from the plate cylinder 07.

At the plate cylinder 07 side facing the shaft 141 for receiving the plate cylinder 07 remote printing plates 101 at least in the employee on the plate cylinder 07 operating state near the lateral surface 107 of the printing cylinder 07 arranged guide member 173 which z. B. in the form of a baffle 173, a wedge 173 or a rolling element 173, z. B. a roller 173 is formed and has the task of leading the trailing end 104 of the plate cylinder 07 to be removed pressure plate 101 in the well 141. A distance a173 of the guide element 173 from the lateral surface 107 of the printing cylinder 07 is preferably not much greater than the length of the folded Einhänlegeels 114 at the trailing end 104 of the pressure plate 101. On the guide member 173 may be mounted a sensor 191, either in contact with the of Plate cylinder 07 to be removed printing plate 101 or advantageously contactless, z. B. inductive, checks whether the suspension leg 114 has actually solved at the trailing end 104 of the plate cylinder 07 to be removed pressure plate 101 after actuation of the arranged in the channel 108 of the printing cylinder 07 holding means 121.

In a preferred embodiment, the suspension leg 114 at the trailing end 104 of the pressure plate 101 to be removed from the plate cylinder 07 after passing through the guide member 173 preferably on a first ramp 174 spaced from the guide member 173 before reaching the support 172 in the shaft 141, wherein the first ramp 174 initially rises in the direction of the support 172 and, after a summit point 176, drops towards the support 172. The first ramp 174 is preferably rigidly connected to the support 172. In the progress of the introduction of the plate cylinder 07 to be removed pressure plate 101 in the shaft 141 hits their suspension leg 114 at the trailing end 104 on a second ramp 177, the edge of which after its summit point 178, d. H. So on the side facing away from the plate cylinder 07 side, preferably abruptly steeply drops to support 172 out. In the direction in which the pressure plate 101 is inserted into the shaft 141, a stop 179 rigidly connected to the second ramp 177 is arranged a short distance behind the summit point 178, against which the suspension leg 114 abuts the trailing end 104 of the pressure plate 101. When the suspension leg 114 abuts against the stop 179 at the trailing end 104 of the pressure plate 101, it preferably engages behind the second ramp 177, in that the suspension leg 114 engages in the intermediate space formed by said distance.

The second ramp 177 and the stop 179 connected to it are movable by a conveyor 181 linearly and parallel to the support 172 in order to move the printing plate 101 to be removed from the plate cylinder 07 completely into the shaft 141. The conveyor 181, which forms in particular together with the steep flank on the second ramp 177 for the folded suspension leg 114 at the trailing end 104 of the pressure plate 101 a pressure plate 101 in the well 141 promotional entrainment is z. B. as a belt drive 181 or as a linear drive 181, preferably as a pneumatic linear drive 181, in particular as a rodless, double-acting linear drive 181 is formed.

On the side facing away from the plate cylinder 07 side a lift 182, in particular a pressure molding lifter 182 is arranged in the shaft 141, wherein the printing form lifter 182, for example, a preferably perpendicular to the support 172 movable piston 183, at the end of a z. B. L-shaped, in particular U-shaped lifting arm 184 is arranged, wherein the bent suspension leg 114 is set at the trailing end 104 of the pressure plate 101 on the lifting arm 184 or set encompassing. The printing form lifter 182 preferably has two stable operating positions, namely a stable operating position with the piston 183 retracted, in which the lifting arm 184 is below the level defined by the support 172, and another stable operating position with the piston 183 extended, in which the lifting arm 184 the printing plate 101 removed from the plate cylinder 07 lifts from the support 172. The printing form lifter 182 thereby executes a stroke s182, which is greater than the length of the folded Einhänbringels 114 at the trailing end 104 of the pressure plate 101. Preferably, the stroke s182 has a value between the single and double the length of Einhänlegeels 114. The printing form lifter 182 thus lifts a printing plate 101 remote from the plate cylinder 07 from a preliminary first storage position to a final second storage position.

Above the printing form lifter 182, in particular above its lifting arm 184, a securing element 186, which is preferably pivotable about a pivot axis extending substantially parallel to the width B of the printing plate 101, is arranged, for. B. in the form of a strip-shaped flap 186, whose or the lower edge is located at a distance a186 from the lifting arm 184, wherein the distance a186 is preferably dimensioned smaller than the length of the folded Einhänlegeels 114 at the trailing end 104 of the pressure plate 101st In the Fig. 9 indicates a direction arrow to the pivoting of the fuse element 186. The securing element 186 secures a printing plate 101 raised by the printing form lifter 182 against unintentional slipping in the shaft 141 or removal from the shaft 141 Operator to first pivot the fuse element 186 before the raised pressure plate 101 can be removed from the shaft 141.

The 10 to 14 By way of example, several stages of the procedure for changing printing plates 101 on a plate cylinder 07 are assumed. It is initially assumed that two printing plates 101 are arranged in the upper shaft 143 to provide new printing plates 101 to be mounted on the plate cylinder 07, that along the plate cylinder 07 from the circumference of two printing plates 101 are placed and that the lower slot 141 for receiving the plate cylinder 07 remote printing plates 101 is empty, ie free of printing plates 101, see. Fig. 10 , The plate cylinder 07 rotates the opening 109 of a channel 108, in which the suspension leg 114 is held at the trailing end 104 of the printing plate 101 to be removed by the plate cylinder 07 by a holding means 121, in a first position, which is below the guide member belonging to the lower tray 141 173 is located. The pressing element 124 is set on the plate cylinder 07 ( Fig. 10 ).

Then, the holding means 121 is pivoted against the force of a spring element 122, whereby the suspension leg 114 at the trailing end 104 of the pressure plate 101 due to its elastic residual stress from the opening 109 snaps and strikes the guide member 173. The employed pressure element 124 secures the pressure plate 101 against further detachment from the lateral surface 107 of the plate cylinder 07.

The plate cylinder 07 then rotates counter to its production direction P and pushes the trailing end 104 of the pressure plate 101 into the shaft 141. When the pressure plate 101 is inserted into the shaft 141, the suspension leg 114 first slides along the trailing end 104 of this pressure plate 101 along the guide element 173 and then positions itself on the first ramp 174 belonging to the shaft 141.

The suspension leg 114 slides the ramp 174 up to about the summit 176 and then reaches the support 172. While the pressing member 124 is still employed on the plate cylinder 07, the pressure plate 101 by rotation of the plate cylinder 07 against its production direction P in the slot 142th inserted. In this case, its suspension leg 114 at the trailing end 104 also overcomes the second ramp 177 connected to the conveying device 181 and abuts against the stop 179 connected to the second ramp 177.

Now the pressing element 124 is turned off by the plate cylinder 07. By the impact of Einhänlegeels 114 of the trailing end 104 on the stop 179, the form-fitting hinged to the front edge 116 of the opening 109 folded becket 113 at the leading end 103 of the pressure plate 101 from the opening 109. The pressure plate 101 is now with its leading end 103 freely on the lateral surface 107 of the printing cylinder 07 on. The plate cylinder 07 has performed from the release of Einhänlegeels 114 at the trailing end 104 until now less than half a turn. The bent suspension leg 114 at the trailing end 104 has hooked between the second ramp 177 and the stop 179. The conveying device 181 connected to the second ramp 177 and the stop 179 can now completely draw the pressure plate 101 into the shaft 141, cf. Fig. 11 ,

The pressure plate 101 is now removed from the plate cylinder 07 and is in its length L to the shaft 141. Her suspension leg 114 at the trailing end 104 is located on the summit point 178 of the second ramp 177, while their leading end 103 on the summit point 176 of the first ramp 174 rests, whereby at least the suspension leg 113 at the leading end 103 preferably hangs freely. The storage of the pressure plate 101 in the shaft 141 is therefore preferably carried out by a support at two points, namely on the summit points 176; 178 of the two ramps 174; 177th

The z. B. pneumatically actuated Druckformheber 182 now raises the in the well 141st retracted pressure plate 101 at its trailing end 104 to just below the securing element 186, wherein the suspension leg 114 rests on the associated with the printing plate lifter 182 lifting arm 184, see. Fig. 12 ,

The arranged close to the plate cylinder 07 alignment device 151 pivots with their previously preferably horizontally oriented diametrical stops 152; 153 preferably by 90 ° in a vertical position, so that a matched to the width B of the plate cylinder 07 to be mounted pressure plate 101 stop 152; 153 immersed in a defined by the support 154 in the shaft 143 transport plane for to be mounted on the plate cylinder 07 pressure plate 101 and immersed on the plate cylinder 07 to be mounted pressure plate 101 during its transport out of the shaft 143 on the stop 152; 153 Seitenregistermäßig is aligned to the plate cylinder 07.

To mount a printing plate 101 to be mounted on the plate cylinder 07, the latter first further rotates counter to its production direction P into a receiving position. The first pressure plate 101 to be mounted on the plate cylinder 07 rests with its suspension leg 114 at its trailing end 104 on the stop 156 connected to a conveyor 157. The conveyor 157 is set in operation, so that the stop 156 in a direction preferably directed tangentially on the plate cylinder 07, the first pressure plate 101 as far from the shaft 143 moves until its leading end 103 touches the employee on the plate cylinder 07 pressing member 124 and the this leading end 103 bent suspension legs 113 between the rear in the production direction P of the printing cylinder 07 edge 117 of the opening 109 and the contact point 188 of the pressure element 124 on the plate cylinder 07, see. Fig. 13 ,

The plate cylinder 07 now changes its direction of rotation and begins to rotate in its production direction P, whereby the set up on the plate cylinder 07 Suspension leg 113 at the leading end 103 of the pressure plate 101 slips into the opening 109 and positively hooked to the front edge 116 of the opening 109. Due to the further rotation of the plate cylinder 07 in its production direction P, the printing plate 101 is completely conveyed out of the shaft 143 and mounted on the plate cylinder 07. During the winding, the pressure plate 101 is rolled on the plate cylinder 07 by the pressure element 124 placed on the plate cylinder 07. After half a rotation of the printing cylinder 07 in its direction of production P, the pressing member 124 presses the folded suspension leg 114 at the trailing end 104 of the pressure plate 101 in the opening 109. The holding means 121 in the opening 108 belonging to this channel 108 was released and is then in that Operating position brought in which it introduced into the opening 109 suspension leg 114 at the trailing end 104 of the pressure plate 101 z. B. fixed by a clamp. The conveyor 157 drives the stop 156 connected to it again into its end position on the side facing away from the printing cylinder 07 side in the shaft 143, see. Fig. 14 , The pressure element 124 is turned off by the pressure cylinder 07 and the alignment device 151 pivots with its diametrical stops 152; 153 again preferably in a horizontal position.

With the method steps described so far, a change of a first printing plate 101 on the printing cylinder 07 is completed by a used printing plate 101 removed and a new printing plate 101 was mounted.

The replacement of a second printing plate 101 takes place essentially in accordance with the method explained above, and further details are referred to above WO 2004/085160 A1 expressly referred.

According to the majority of recorded on the respective plate cylinder 07 in the axial direction pressure plates 101 may preferably be provided in a manner not shown that in the plate changing device 11 in the axial direction of Plate cylinder 07 seen several printing plates 101 are arranged side by side. In this context, it is expedient if in each case also not shown in detail, each of the juxtaposed printing plates 101 is assigned at least one pressing element 124, wherein it is particularly preferred if each at least one pressure plate 07 associated pressing member 124 is independently operable by the other printing plates 101 associated pressing elements 124, so that the supply and discharge for each printing plate 101 can be performed independently of another printing plate 101.

For receiving a plurality of juxtaposed printing plates 101 in the plate changing device 11, this can a plurality of shaft-like areas 141; 143 and shafts 141; 143, wherein at least two shaft-like regions 141; 143 may be arranged side by side, but preferably the number of juxtaposed shaft-like areas 141; 143 corresponds to the number of on the associated plate cylinder 07 in the axial direction next to each other can be arranged pressure plates 101.

Furthermore, in particular in the case of two printing plates 101 arranged one behind the other on a plate cylinder 07 in the circumferential direction, it is possible for two plate-like regions 143; 141 are arranged one above the other. Here, one of the two superimposed areas 143; 141, a feed level 143, z. B. a Zuführschacht 143 and the other of the superposed areas 141; 143 a discharge plane 141, z. In detail, the arrangement is expediently such that the plate changing device 11 comprises a number of printing plates 101 on the associated plate cylinder 07 corresponding number of juxtaposed Zuführschächten 143 and a corresponding number of below the Zuführschächte 143 arranged Abführschächten 141. The number of juxtaposed feed chutes 143 of the plate changing device 11 can in particular be four or six.

In the case of a plurality of printing plates 101 arranged next to one another on a plate cylinder 07, each printing plate 101 is in each case a channel 108 (cf. Fig. 4 ) or a portion of a channel 108 for receiving the angled front end 113 of each pressure plate 101 assign. Preferably, it is provided that for juxtaposed pressure plates 101 each have a correspondingly long channel 108 is formed, which may be formed continuously in particular in the axial direction of the plate cylinder 07.

As described above, holding means 119 for holding the suspension legs 113 of the printing plates 101 are provided in the channels 108 (see FIG. Fig. 4 ), which in particular may comprise the holding means 121, the spring elements 122 and the adjusting means 123. In order to be able to design a plate change independent of a plate change of another printing plate 101 for each printing plate 101, a separate holding device 119 is provided for each printing plate 101 in the case of a plurality of axially adjacent to each other on a plate cylinder 07 printing plates 101 and each holding device 119 is independent of the other holding means 119 operable, in particular pneumatically actuated.

While in the Fig. 9 to 14 the plate changing operation has been explained for the case that the production direction P coincides with the direction in which the printing plates 101 are fed, that is, in the case of the printing units 03; 21; 29; 32 (cf. Fig. 1 and 2 ), the plate changing operation differs in the case of the other printing units 04; 22; 28; 31 on the other hand as follows:

First, it will open again Fig. 1 Referenced. It is assumed that in the nine-cylinder satellite printing unit 16, the substrate web 23 in the printing unit 22 with the color black, in the printing unit 04 with the color cyan, in the printing unit 03 with the color Magenta and printed in the printing unit 21 with the color yellow one after the other. Accordingly, the wear the printing units 22; 04; 03; 21 associated printing plates 101 a; 101b; 101 c and 101 d printed images 105 of the corresponding color, namely the printing plates 22 associated printing plates 101 a a print image 105 a for the color black, the printing unit 04 associated printing plates 101 b, a printed image 105 b for the color cyan associated with the printing unit 03 Printing plates 101c a print image 105c for the color magenta and the printing plate 21 associated printing plates 101d a printed image 105d for the color yellow, see. Fig. 5 ,

Fig. 5 outlines the printing plates 101a; 101b; 101c and 101d associated with the associated print images 105a; 105b; 105c and 105d for this nine-cylinder satellite printing unit 16. At the same time, the orientation of the printed images 105a; 105b; 105c and 105d relative to the associated printing plates 101a; 101b; 101 c and 101 d to recognize and by the respective arrow the production direction P or direction P of the respective printing plate 101a; 101b; 101c and 101d are shown on the corresponding plate cylinder 07 during the production operation. The leading in production operation end of each print image 105a; 105b; 105c; 105d is denoted by the reference numeral 106, the trailing end in the production process with the reference numeral 110. It can be seen that the printed images 105a and 105b opposite the printed images 105c and 105d are applied in opposite orientation on the respective printing plates 101 a and 101 b. It can also be seen that the orientation of the printing plates 101 a and 101 b relative to the direction of production P is opposite to the orientation of the printing plates 101 c and 101 d, so that ultimately all the printed images 105 a; 105b; 105c and 105d are aligned in the same orientation to the direction of production P.

The process of mounting the printing plates 101 a; 101 b takes place in the case of the printing units 22 and 04 now so that the corresponding printing plates 101 a; 101 b are mounted with their first end 103 at the first front edge 116 of the plate cylinder 07 and the direction of rotation of the corresponding plate cylinder 07 for the purpose of Mounting the printing plates 101a; 101b is reversed until the second end 104 of the pressure plate 101a; 101b is suspended and attached to the second rear edge 117 of the plate cylinder 07, and that then the direction of rotation of the plate cylinder 07 is again reversed in the production direction P for a subsequent printing operation. Here, in the case of these printing plates 101a; 101b, the running direction P in the printing operation so that the second end 104, which is usually the trailing end in the prior art, now represents the leading end.

The above embodiments are applicable to the overhead nine-cylinder satellite pressure unit 17 accordingly, in which case the printing units 31; 28 those printing units 31; 28, in which the printing plates 101c and 101d have leading ends 104 in printing operation and printed images 105c applied in opposite orientation to the prior art; 105d wear. In the case of the nine-cylinder satellite printing unit 17 are in the described embodiment, these printing units 31; 28 assigned the colors magenta or yellow.

In Fig. 15 the above facts are again sketched schematically. It shows different operating phases of the plate cylinder 07, for example, the printing units 29; 28 or 32; 31, namely phase A, in which the first end 103 of the respective pressure plate 101 has been hooked into the channel 108 of the plate cylinder 07, more precisely via its first front edge 116 and the process of drawing up a pressure plate 101 begins, phase B, in FIG the plate cylinder 07 rotates to mount the printing plate 101 and the printing plate 101 is already partially wound up, phase C, in which the mounting of the printing plate 101 is finished on the plate cylinder 07 and thus also the second end 104 of the pressure plate 101 in the channel 108, more precisely has been suspended over its second rear edge 117 and possibly fixed there, and phase D, in which the plate cylinder 07 rotates for the purpose of printing in the direction of production P. The left column shows a plate cylinder 07, for example, the printing units 29; 32 and the right one Column shows a plate cylinder 07, for example, the printing units 28; 31 of the nine-cylinder satellite printing unit 17. The same applies to the nine-cylinder satellite printing unit 16, but the arrangement is mirrored about a vertical center plane M.

As seen from the left column of Fig. 15 can be seen, the plate cylinder 07 rotates here during the phase of drawing up a pressure plate 101c; 101 d in the direction of production P, while in the case of the right column, the direction of rotation D of the plate cylinder 07 when mounting a printing plate 101 a; 101 b is directed opposite to the direction of production P and is reversed after mounting.

In the case of the embodiments described above, the circumference of the satellite cylinder 18 corresponds to the circumference of the plate cylinder 07 or forme cylinder 07; in the case of a circumference of the plate cylinder 07 from one side, especially newspaper page, the circumference of the satellite cylinder 18 also corresponds to one side, especially newspaper page, in the case of a circumference of the plate cylinder 07 from two sides, especially newspaper pages, the circumference of the satellite cylinder 18 also corresponds to two sides, in particular newspaper pages. The circumference of the satellite cylinder 18 is thus in the case of the first alternative mentioned above equal to the section length of the plate cylinder 07 and in the case of the second alternative mentioned above equal to twice the section length of the plate cylinder 07th

In general, the circumferential ratio of the satellite cylinder 18 and the plate cylinder 07 can in particular be designed such that the circumference of the satellite cylinder 18 corresponds to an integral multiple of the section length of the plate cylinder 07.

In the Fig. 16 is an example of a part of the printing unit 21 of the printing tower 14 according to Fig. 1 shown; the other printing units 03; 04; 22; 28; 29; 31; 32 are formed accordingly.

In the illustrated example, the rotary press operates in a wet offset printing process. The transfer cylinder 06 generates with each of its revolutions on the printing substrate 23, preferably on a paper web 23, at least one printed image. In the in the Fig. 16 shown operating case of the printing unit 21 are at the forme cylinder 07 at least one inking unit 09 and a dampening unit 08 employed.

The inking unit 09 has a plurality, preferably at least three rollers 203; 204; 206, z. B. inking rollers 203; 204; 206, which are employed in an ongoing production process of the rotary printing machine to the forme cylinder 07. Between a printing ink from a color reservoir 207 receiving ink fountain roller 208 and the ink on the forme cylinder 07 applying inking rollers 203; 204; 206 are a plurality of rollers 209; 211; 212; 213 arranged. The roller 209 following the ink fountain roller 208 in the direction of conveyance of the ink is formed as a film roller 209. Then, in the transporting direction of the ink after the film roller 209, there is provided a roller 211 formed as a paint flow separating roller 211 which divides a paint stream 2A coming from the ink fountain roller 208 into a main stream 2B and a sub stream 2C. In the Fig. 16 the leading to the forme cylinder 07 course of the main flow 2B is indicated by a solid line and also leading to the forme cylinder 07 course of the secondary flow 2C by a dashed line.

In the main stream 2B and in the sub-stream 2C, one of the ink flow separating roller 211 on at least one of the inking rollers 203; 204; 206 ink transferring roller 212; 213, said roller 212; 213 each as a rubbing roller 212; 213 is formed. The two friction rollers 212; 213 perform a running in their respective axial direction traverse stroke, the traverse stroke of a friction roller 212 z. B. may be coupled by a lever assembly with the traverse stroke of the other friction roller 213. In an alternative embodiment, the traverse stroke of the respective friction roller 212; 213 generated by independent drives. By both Drive variants, the two traversing strokes can be designed in opposite directions. The traverse stroke of the respective friction roller 212; 213 can z. B. be generated by means of a gear from the rotational movement. Both in the main stream 2B and in the secondary stream 2C ink taken from the ink reservoir 207 is in each case by means of a five juxtaposed rollers 208; 209; 211; 212; 213; 203; 204; 206 having applied to the plate cylinder 07, wherein the ink fountain roller 208, the film roller 209, the ink flow separation roller 211, one of the friction rollers 212; 213 and one of the inking rollers 203; 204; 206 are each part of each of the forme cylinder 07 leading compactor. Accordingly, only a single roller 209 is arranged in the roller train between the ink fountain roller 208 and the ink flow separation roller 211, this roller 209 being designed as a film roller 209

The main current 2B is that part of the Farbduoms 2A coming from the ink fountain roller 208, which is taken in the direction of rotation of the ink flow separation roller 211 of this Farbstromtrennwalze 211 and first passed through the arranged in this main flow 2B Reibwalze 212 in the direction of the forme cylinder 07. That part of the Farbduoms coming from the ink fountain roller 201 211 downstream of the main stream 2B is removed in the direction of rotation of the Farbstromtrennwalze 211 of this Farbstromtrennwalze 211 and forwarded in the direction of the forme cylinder 07 is referred to as the secondary stream 2C taken from the ink reservoir 207 ink. The secondary stream 2C can turn into further partial streams 2D; 2E be divided if at the arranged in the secondary flow 2C friction roller 213 more, in particular two of the inking rollers 204; 206; 203 are employed. Since the main stream 2B of color ink coming from the ink fountain roller 208 2A the forme cylinder 07 in the direction of rotation first, ie at least spatially before the side stream 2C and its partial streams 2D; 2E, such an inking unit 09 is referred to as front-heavy. The in the secondary stream 2C of coming from the ink fountain roller 208 color flow 2A ink is transported z. B. applied to the pre-colored by the main stream 2B form cylinder 07. Also found by the to the side stream 2C and its Partial flows 2D; 2E belonging to inking rollers 204; 206, a smoothing of the applied in the main stream 2B on the forme cylinder 07 portion of the ink instead. Such an inking unit 09 produces a uniform application of ink on the forme cylinder 07 to be inked. An inking unit 09 whose main flow 2B of color ink 2A coming from the ink ductor 208 is the forme cylinder 07 in its direction of rotation only after the secondary flow 2C applied on the forme cylinder 07 and its partial streams 2D; 2E is referred to as Hinterlastig.

The ink reservoir 207, from which the ink fountain roller 208 removes the ink to be transported to the forme cylinder 07 is z. B. as a color box 207 or as a color tray 207, wherein the color box 207 or on the ink tray 207 in the axial direction of the ink fountain roller 208 strung together several, z. B. thirty to sixty color knives (not shown) are provided, which are each preferably remotely adjustable with an adjusting means, not shown in their respective employment of the ink fountain roller 208 and actually employed, whereby a zonewise metering of the ink fountain roller 208 recorded ink is possible. The dosage of the ink quantity made with the setting of the respective inking knife is expressed in a layer thickness of the printing ink proportional to this setting in the relevant zone on the jacket surface of the ink fountain roller 208. The inking unit is accordingly designed as a zone inking unit in the preferred embodiment.

The rollers 203; 204; 206; 208; 209; 211; 212; 213 of the inking unit 09 have in their respective axial direction a length z. B. in the range of 500 mm to 2,600 mm, in particular in the range of 1,400 mm to 2,400 mm. Your outer diameter is z. B. in the range between 50 mm and 300 mm, preferably between 80 mm and 250 mm.

The Farbstromtrennwalze 211 has a lateral surface preferably made of an elastic material, for. B. made of a rubber.

The dampening unit 08 is preferably as a dampening means contactless applying dampening 08, z. B. formed as a spray dampening unit, so that it has a spray bar 219, wherein preferably a plurality of arranged in the spray bar 219 spray nozzles the dampening solution to a z. B. as a dampening drive roller 221 formed roller 221 of the dampening 08 spray. The dampening agent sprayed on the dampening drive roller 221 is replaced by another z. B. as a smoothing roller 222 formed roller 222 of the dampening unit 08 on the dampening roller 218 and transferred from there to the forme cylinder 07.

In the Fig. 16 is the direction of rotation of the respective rollers 203; 204; 206; 208; 209; 211; 212; 213 of the inking unit 09, the rollers 218; 221; 222 of the dampening unit 08 and the cylinder 06; 07 each indicated by an associated arrow. The cylinders 06; 07 are driven as described above. In the inking unit 09 is only one of the friction rollers 212; 213, namely either the friction roller 212 or the friction roller 213 by a drive 253; 254, z. B. an electric motor 253; 254 driven. In the Fig. 16 the preferred embodiment is shown in which the friction roller 212 is driven and the friction roller 213 has no motor. The other alternative is intended to be indicated by the fact that a drive 253 is shown for the friction roller 212 only in dashed representation. The remaining rollers 203; 204; 206; 208; 209; 211 of the inking 09 are friction-driven and thus have no own motor drive. In order to enable a change of the middle inking roller 204, the upper friction roller 213 is pivoted by a mechanical device in a direction that increases its axial distance a213 to the forme cylinder 07, so that the central inking roller 204 substantially by a vertically upward movement of the Region between the forme cylinder 07 and the upper friction roller 213 can be removed.

The uppermost inking roller 206 of the inking unit 09 is arranged such that in its employed to the forme cylinder 07 operating state at the periphery of this Ink application roller 206 applied horizontal tangent T206 of a applied to the circumference of the forme cylinder 07 horizontal tangent T07 at a vertical distance a206 of at least 50 mm. This vertical distance a206 forms, so to speak, an offset between the uppermost inking roller 206 and the forme cylinder 07. By this arrangement results from an operating page of the printing unit 21 of sufficient accessibility to the forme cylinder 07, especially since all the other inking unit 09 belonging rollers 203; 204; 208; 209; 211; 212; 213 are arranged clearly below the horizontal tangent T206 applied to the circumference of the uppermost inking roller 206. The rollers 218; 221; 222 of the dampening unit 08 are arranged substantially below the forme cylinder 07 and also do not limit the accessibility to the forme cylinder 07. The accessibility to the forme cylinder 07 must z. B. therefore given to be able to change on the lateral surface of the forme cylinder 07 in the shortest possible time one or more printing plates 101. A change of printing plates 101 can be carried out automatically on the forme cylinder 07 with the aid of a plate changing device 11, preferably tangentially attached to the forme cylinder 07.

Despite the comparatively small number of ink gaps in the ink to plate cylinder 07 transporting compactor produces the illustrated inking unit 09 on the plate cylinder 07 a uniform application of paint, because there are more rollers provided where they are particularly needed for smoothing the paint, namely in direct contact with the plate cylinder 07, where preferably three inking rollers 203; 204; 206 are provided. In particular, by a special, namely stochastic structure of the lateral surface of the film roller 209 is achieved that the inking unit 09 is prone to stenciling. As a result, a printed product with a high print quality can be achieved with this inking unit 09 even in newspaper printing, which takes into account the ever-increasing quality demands in newspaper printing. Even in a high-speed printing machine with a transport speed of the printing material 23 of more than 10 m / s, preferably in the range between 10 m / s and 15 m / s, as it is commonly used in newspaper printing, occurs due to the short roller train and the film roller 209 used, the undesirable effect of the color fog hardly. The use of in the Fig. 16 described inking unit 09 in a rotary printing machine, especially in a designed as a printing tower 14 newspaper printing press, is further explained in the following figures.

Fig. 17 and 18 show in a schematic sketch again in the Fig. 16 shown part of the printing unit 21, now in particular the storage of the cylinder 06; 07 and a respective adjustment of the inking rollers 203; 204; 206, the film roller 209, the ink jet separating roller 211, the dampening roller 218 and the dampening driving roller 221 are highlighted. The representations in the Fig. 17 and 18 differ in that Fig. 17 shows a first operating state with preferably each closed compactors, which means that z. B. the inking rollers 203; 204; 206 to the forme cylinder 07 and to one of the friction rollers 212; 213 are employed and that the dampening roller 218 is employed on the forme cylinder 07 and on the smoothing roller 222. Fig. 18 shows, however, a second operating state with preferably each open, ie interrupted by a gap pulleys, which means that z. B. the inking rollers 203; 204; 206 and / or the dampening roller 218 are at least offset from the forme cylinder 07.

All rollers 203; 204; 206; 208; 209; 211; 212; 213 of the inking unit 09, the rollers 218; 221; 222 of the dampening unit 08 and the cylinder 06; 07 are each arranged at a distance from each other, in opposite standing frames 02 and 27 of the printing tower 14 (FIG. Fig. 1 rotatably mounted, wherein at least the inking rollers 203; 204; 206 and the dampening roller 218, but preferably also the film roller 209 and the ink flow separation roller 211 of the inking unit 09 and the dampening drive roller 221 of the dampening unit 08 are each arranged radiallyhubfähig. The radial stroke of these rollers 203; 204; 206; 209; 211; 218; 221 refers to that the respective axis of these rollers 203; 204; 206; 209; 211; 218; 221 or at least one of the ends of these rollers 203; 204; 206; 209; 211; 218; 221 opposite to the respective roller 203; 204; 206; 209; 211; 218; 221 belonging frame-fixed bearing point is eccentrically adjustable. The eccentric displacement of each of the rollers 203; 204; 206; 209; 211; 218; 221 is carried out in each case by means of preferably several, z. B. four each symmetrical and concentric about the respective axis of these rollers 203; 204; 206; 209; 211; 218; 221 arranged actuators 223, as exemplified in the Fig. 17 and 18 is shown, preferably even to the same roller 203; 204; 206; 209; 211; 218; 221 belonging actuators 223 can be actuated individually and independently of each other by a control unit and set to a specific travel, each actuated actuator 223 each with respect to the roller 203; 204; 206; 209; 211; 218; 221, to which it belongs, exerts a radial force, this force being the axis of this roller 203; 204; 206; 209; 211; 218; 221 moves radially or at least tries to move. If several at the same end of one of the rollers 203; 204; 206; 209; 211; 218; 221 arranged actuators 223 are actuated simultaneously, resulting from the axis of the respective roller 203; 204; 206; 209; 211; 218; 221 executed radial stroke from a vector sum of the respective radial force of actuated actuators 223. The actuators 223 are z. B. subjected to a pressure medium; Preferably, they are pneumatically operated. The actuators 223 are z. B. in each case one end of the respective roller 203; 204; 206; 209; 211; 218; 221 receiving roller lock arranged. The from the axis of the respective roller 203; 204; 206; 209; 211; 218; 221 executable radial stroke is preferably in the range of a few millimeters, z. B. it is up to 10 mm, which is sufficient to the respective roller 203; 204; 206; 209; 211; 218; 221 of at least one adjacent cylindrical rotary body, for. B. the forme cylinder 07, turn off. It is also provided that with the respective actuators 223 one of the respective roller 203; 204; 206; 209; 211; 218; 221 is set against its at least one adjacent rotating body applied contact pressure, wherein the measure of the set contact force by the controlled with this setting transport of ink or dampening influences the quality of the printed product generated in connection with this inking unit 09 and / or dampening unit 08. The Contact force is built up when already a physical contact between the respective roller 203; 204; 206; 209; 211; 218; 221 and its adjacent body of revolution, but still by the operation of one or more actuators 223, the at least one effective radial force is increased. By further or renewed actuation of one or more actuators 223, an existing contact force in its amount changed, for. B. also be reduced.

With the adjustment of the contact pressure, one of the rollers 203; 204; 206; 209; 211; 218; 221 exerts on its adjacent body rotation, also a width of a in touch contact between this roller 203; 204; 206; 209; 211; 218; 221 and the adjacent rotary body forming roller strip set, wherein the roller strip as a flattening on the lateral surface of the roller 203; 204; 206; 209; 211; 218; 221, on the lateral surface of the with the roller 203; 204; 206; 209; 211; 218; 221 cooperating cylindrical rotating body or on the lateral surface of both represents. The width of the roller strip is the chord forming by the flattening on the otherwise circular cross section of the roller 203; 204; 206; 209; 211; 218; 221 or the rotating body cooperating with it. The flattening is due to an elastically deformable lateral surface of the roller 203; 204; 206; 209; 211; 218; 221 or the cooperating with her body of revolution possible. A roll strip is also referred to as a nip point. In the control unit controlling the actuators 223, values may be stored for their respective pressure level, to which the respective actuators 223 are to be set, in order to apply to a specific roller 203; 204; 206; 209; 211; 218; 221 form a roller strip of a certain width to its adjacent body of revolution by the contact force resulting from the respective setting of the actuators 223.

The cylinders 06; 07, ie the transfer cylinder 06 and the forme cylinder 07 are, as shown in the Fig. 17 and 18 each stored in a storage unit 224, preferably both ends of the respective cylinder 06; 07 each in such a Bearing unit 224, z. B. linear bearing 224 are stored. The bearing unit 224 allows the respective cylinder 06; 07 a linear displacement S. Details of the preferred bearing unit 224 are in the Fig. 19 shown.

The one on / Abstellmechanismus for the respective cylinder 06; 07 integrating bearing unit 224 has in addition to a bearing 226, z. B. radial bearing 226, for example, a cylindrical roller bearing 226, for rotatably supporting the respective cylinder 06; 07 storage means 227; 228 for a radial movement of the respective cylinder 06; 07 - for pressure on or pressure off - on. For this purpose, the bearing unit 224 after its installation in or on a frame of the printing press frame-fixed, carrier-fixed bearing elements 227 and the movable against these bearing elements 228 on. The carrier-fixed and movable bearing elements 227; 228 are as cooperating linear elements 227; 228 and together with corresponding sliding surfaces or rolling elements between them as a total of a linear bearing 227, 228 formed. The linear elements 227; 228 take in pairs a radial bearing 226 receiving, z. B. formed as a carriage 229 bearing block 229 between them. Bearing block 229 and the movable bearing elements 228 may also be made in one piece. The carrier-fixed bearing elements 227 are arranged on a support 231, which in total with one of the frames 02; 27 ( Fig. 1 ) is connected. The carrier 231 is designed, for example, as a carrier plate which, for example, at least on a drive side of the respective cylinder 06; 07 a recess for the passage of a shaft, z. B. a drive shaft of an in Fig. 19 Having not shown cylinder pin. Also, the frame wall on the drive side preferably has a recess or an opening for a drive shaft. On the opposite side of the drive side does not necessarily have a recess or a recess in the frame 02; 27 may be provided.

Preferably, a length of the linear bearing 227, 228, in particular at least a length of the bearing means 227 of the linear bearing 227 that is fixed in the mounted state in the assembled state, is 228, in the direction of the travel S considered smaller than a diameter of the associated cylinder 06; 07. The bearing block 229 preferably has only a single degree of freedom of movement in the direction of the travel S.

The storage unit 224, which is preferably designed as a unit which can be assembled as a whole, forms z. B. an optionally partially open housing from z. B. the carrier 231 and / or z. B. a frame (in Fig. 19 without reference z. B. the four storage unit 224 to all four sides outwardly bounding plates). Within this housing or this frame are the radial bearing 226 bearing block 229, the bearing elements 227; 228, z. B. the linear guides 227; 228, z. B. linear bearing 227; 228 and in an advantageous embodiment, for. B. a bearing block 229 linearly adjusting actuator 232 or more such actuators 232 housed. The frame-fixed bearing elements 227 are arranged substantially parallel to one another and define the direction of the travel S ( Fig. 19 ).

Pressure is applied by moving the bearing block 229 in the direction of the pressure point by means of a force F applied to the bearing block 229 by at least one actuator 232, in particular by at least one force-controlled actuator 232, by means of which a defined or definable force F in is provided for setting Pressure on direction can be brought to the bearing block 229 ( Fig. 19 ). The decisive for the color transfer and thus the print quality, among other things, line force in the respective nip point is therefore not by a travel S, but by the force equilibrium between the force F and between the cylinders 06; 07 resulting line force F _L and the resulting equilibrium defined. In a first, not specifically illustrated embodiment, the cylinder 06; 07 employed in pairs by the bearing block 229 is acted upon by the correspondingly set force F via the / the actuator (s) 232. For basic adjustment of a system (with corresponding elevators on the cylinders 06, 07) is provided in an advantageous embodiment, that at least the respective transfer cylinder 06 of the printing unit 03; 04; 21; 22; 28; 29; 31; 32 in one by the Force equilibrium found Anstelllage fixable or at least wegbegrenzbar.

Particularly advantageous is an embodiment in which the bearing block 229 - even during operation of the printing press - at least in a direction away from the pressure point against a force, for. B. spring force, in particular a definable force, is movably mounted. This is - in contrast to the pure travel limit - on the one hand, a maximum line force in the interaction of the cylinder 06; 07 defined, and on the other hand allows yielding, for example, in a web break with subsequent winder on one of the cylinder 06; 07th

The bearing unit 224 has on its side facing a pressure point - at least during the setting process - a location-adjustable stop 233, which limits the travel S to the pressure point out. The stop 233 is spatially variable in such a way that an effective as a stop stop surface 234, whose reference numerals in the Fig. 19 is shown in an outbreak of the bearing block 229, along the travel S at least in one area is variable. It is thus provided by adjustable stop 233 in an advantageous embodiment, an adjusting device by means of which the position of a pressure near the end position of the bearing block 229 is adjustable. For Wegbegrenzung / adjustment serves z. B. a wedge drive described below. The placement of the stop 233 can basically be done manually or via an actuating means 236 designed as an actuator 236.

Next is an advantageous embodiment in Fig. 19 not shown holding or clamping means provided by means of which the stop 233 can be set in the desired position. Further, at least one resilient element 237, z. B. spring element 237, is provided, which applies a force F _R from the stop 233 in a direction away from there on the bearing block 229. Ie. the spring element 237 causes pressure-off in the event that the bearing block 229 is not prevented from moving in any other way. Pressure is applied by moving the Bearing block 229 in the direction of the stop 233 by at least one actuator 232, in particular a force-controlled actuator 232, by means of which for the employment of the respective cylinder 06; 07 either a defined or definable force F in print-on direction on the bearing block 229 can be brought. If this force F is greater than the restoring force F _{R of} the spring elements 237, so takes place with appropriate spatial training a hiring of the respective cylinder 06; 07 to the adjacent cylinder 06; 07 and / or a hire of the bearing block 229 to the stop 233rd

Ideally, the applied force F, the restoring force F _R and the position of the stop 233 is selected such that no substantial force ΔF is transmitted between the stop 233 and the abutment surface of the bearing block 229 in the set position, for example | ΔF | <0.1 * (F-F _R ), in particular | ΔF | <0.05 * (F-F _R ), ideally | AF | ≈0. In this case, the contact force between the cylinders 06; 07 substantially determined by the voltage applied by the actuator 232 force F. The decisive for the color transfer and thus the print quality, among others decisive line force F _L in the respective nip point is therefore not primarily by a travel S, but at quasi-free stop 233 defined by the force F and the resulting balance. In principle, after finding the basic setting with the appropriate forces F, it would be conceivable to remove the stop 233 or a corresponding fixation effective only during the basic setting.

The actuator 232 can in principle be designed as an arbitrary actuator 232 applying a defined force F. Advantageously, the actuator 232 is designed as actuatable by a pressure medium adjusting means 232, in particular as a piston 232 movable by a fluid. Advantageous in terms of possible tilting is the arrangement of several, here two, such actuators 232. As the fluid is preferably because of their incompressibility, a liquid, for. As an oil or water, used.

For actuation of the here as a hydraulic piston 232 running actuators 232 is in the Storage unit 224 a controllable valve 238 is provided. This is performed, for example, electronically controlled and provides a hydraulic piston 232 in a first position without pressure or at least to a lower pressure level, while in another position a force F conditional pressure 2P is applied. In addition, a non-designated leakage line is provided here for safety.

In order to avoid too large An- / Abstellwege and still hedge Bahnwickler, can on the remote pressure side of the bearing block 229 a travel limit by a mobile, force-limited stop 239 as overload protection 239 z. B. be provided in conjunction with a spring element, which in the operative pressure-off position, d. H. the pistons 232 are unloaded and / or retracted, although serve as a stop 239 for the bearing block 229, but in the case of a web winder or other excessive forces originating from the pressure point yields and gives way to a greater distance. A spring force of this overload protection 239 is therefore chosen to be greater than the sum of the forces from the spring elements 237. When operational on / off is therefore only a very short travel, z. B. only 1 mm to 3 mm, providable.

The stop 233 is in the illustrated embodiment ( Fig. 19 ) as a transversely movable to the direction of the travel S wedge 233, wherein the same moves the position of the respective effective stop surface 234 along the travel S varies. The wedge 233 is supported, for example, on a carrier-fixed stop 241.

The executed here as a wedge 233 stop 233 is moved by an actuator 236, for example, by a pressure medium actuatable actuating means 236, z. B. a piston actuatable with a pressure medium 236 in a working cylinder with (double-acting) piston via a z. Example, as a piston rod 242 executed transmission member 242 or by an electric motor via a threaded spindle designed as a transfer member 242. This actuator 236 can either be effective in both directions or, as shown here, designed as a one-way actuator, which when activated operates against a return spring 243. The force of the return spring 243 is chosen so weak from above reasons (largely force-free stop 233) that the wedge 233 is held only in its correct position against gravity or vibration forces.

In principle, the abutment 233 can also be designed in another way (for example as a plunger that can be adjusted and fixed in the direction of adjustment) in such a way that it has a stop surface 234 which can be fixed in the direction of the travel S and, at least during the adjustment process, can be fixed forms for the movement of the bearing block 229 in the direction of pressure point. In one embodiment, not shown, a location of the stop 233 takes place, for example, directly parallel to the direction of the travel S by a drive means, for example, a pressure medium actuated cylinder with (double-acting) piston or an electric motor.
