Fig. 5 shows a section of the in the Fig. 4 illustrated arrangement in a different perspective. The Fig. 3 and 6 are each perpendicular to the axis of the forme 06 standing sectional views, wherein Fig. 3 shows an operating state in which the rollers 14 are turned off from the lateral surface of the forme cylinder 06, and wherein Fig. 6 shows an operating state in which the rollers 14 are employed on the lateral surface of the forme cylinder 06.

The sectional views of the Fig. 3 and 6 is particularly in connection with the Fig. 1 Removable that the forme cylinder 06 has a plurality, preferably two circumferentially offset, preferably diametrically opposed axially parallel channels 07, each of these channels 07 preferably as an introduced on the lateral surface of the forme cylinder 06, z. B. rectangular groove or is formed as a bore. The extending in the axial direction of the forme cylinder 06 channels 07 have on the lateral surface of the forme cylinder 06 preferably in each of the sections A; B; C; D each have a slot-shaped opening 08 with a slot width of less than 5 mm, through which in each case at least one end of a in the relevant section A; B; C; D to be arranged on the forme cylinder 06 printing forme 01 can be inserted into the respective channel 07, wherein this relevant end then held in the channel 07 and thus the relevant printing forme 01 is fixed on the lateral surface of the forme cylinder 06. The slot width of the opening 08 dimensioned in the circumferential direction of the forme cylinder 06 is preferably in the range between 1 mm and 3 mm.

In the channels 07 of the forme cylinder 06 each pneumatically actuated holding devices are arranged ( Fig. 16 ; 17 ). A compressed air supply to the forme cylinder 06 by means of an attachable to an end face of the respective forme cylinder 06 compressed air supply device 28, which in the Fig. 7 in the drawing a) in the attached to the forme cylinder 06 state, in the drawing b) as a single part and in the drawing part c) is shown in a sectional view. The 8 and 9 again show a longitudinal section through this in the Fig. 7 It can be seen that this compressed air supply device 28 has a rotationally fixed annular outer part 29, on which connections 31 are formed for the supply of compressed air, and a connected to a journal 32 of the forme 06, rotatable together with the forme cylinder 06 inner part 33, which is why This type of compressed air supply 28 is also referred to as a rotary inlet. Part of the z. B. on a roller bearing outer part 29 of the compressed air supply 28 is axially displaceable relative to the inner part 33, so that the outer part 29 has at least two operating positions, namely an operating position, passed in the externally supplied compressed air to the inner part 33 and then into the forme cylinder 06th is initiated, and another operating position in which the compressed air supply to the forme cylinder 06 is locked because externally supplied compressed air can not be passed to the inner part 33. On the forme cylinder 06, only a single compressed air supply device 28 is provided, ie only on one of its end faces.

Fig. 10 shows the compressed air supply device 28 again in a longitudinal section in a schematic representation. The in the Fig. 8 to 10 exemplified larger pneumatic connection 31 close to the bale of the forme cylinder 06 is used to be introduced into the channels 07 compressed air supply, whereas the two smaller, in particular in the 8 and 9 recognizable pneumatic connections 31 an operation of the relative to the inner part 33 slidable outer part 29 is used, ie the choice of the respective operating position. The compressed air supply device 28 is preferably remotely operable. In the Fig. 10 a force acting in the axial direction of the forme cylinder spring element 34 is indicated 34, which displaces the outer part 29 after a change of its operating position relative to the inner part 33 by a spring force back into its starting position. It is advantageous that the compressed air to be distributed on the forme cylinder 06 at its respective holding devices by means of only a single line from an external pressure medium source to the rotating or at least rotatable forme cylinder 06 is transferred. Although the compressed air to be distributed on the forme cylinder 06 is preferably introduced radially into the outer part 29 of the compressed air supply device 28, it is then forwarded coaxially to the forme cylinder 06 from the inner part 33 of the compressed air supply device 28, ie introduced into an end face of the forme cylinder 06 (FIG. 8 to 11 ), wherein the distribution of the introduced compressed air from this single line then takes place by means of at least one arranged in a recess of the forme 06 device, which is preferably near the front, in particular outside the sections A; B; C; D; e; F, ie outside the printing area of the lateral surface of the forme cylinder 06, is arranged ( Fig. 11 ).

Doppelumfangsformzylinder 06 also have two mutually offset by 180 ° channels 07, whereas a Einfachumfangsformzylinder 06 has only a single axis-parallel channel 07, the opening 08 receives both the leading edge 02 and the rear edge 12 of the same printing forme 01 for their attachment to the forme cylinder 06 , Due to their smaller diameter, a straight-line tangential employment of a holding device to a Einfachumfangsformzylinder 06 is more difficult to accomplish, since the space required for this in the region of the respective Einfachumfangsformzylinders 06 is very limited. A Doppelumfangsformzylinder 06 offers due to its larger diameter rather opportunity for a straight tangential employment of the protection 09 of a holding device on the circumference. On a Einfachumfangsformzylinder 06, the protection 09 of the holding device in the direction of feeding the printing forme 01 to the respective forme cylinder 06 is preferably formed at least partially curved, although the protection 09 of this holding device can also be employed tangentially to the circumference of the respective Einfachumfangsformzylinders 06. Thus, the design of the protection 09 of the respective holding device - whether the protection 09 z. B. is rectilinear or curved and / or whether it is employed radially or tangentially to the respective form cylinder 06 - which also depends on the diameter of the respective forme 06 dependent concrete installation conditions on the respective printing unit adapt.

• Da die Druckform 01 vom Haltemittel 11 in einer in einer Ebene beweglichen, insbesondere schwenkbaren Rückhaltevorrichtung kraftschlüssig gehalten wird, ist eine registerhaltige Ausrichtung der Einhängekante 02 zusammen mit einer gleichzeitigen Fixierung der Druckform 01 möglich.

With the proposed solution, in particular the following advantages can be achieved:

• Since the printing forme 01 is held frictionally by the holding means 11 in a movable in a plane, in particular pivotable retaining device, a register-oriented alignment of the suspension edge 02 together with a simultaneous fixation of the printing plate 01 is possible.

By retracting the printing forme 01 it is fixed in its aligned position after being hung on the forme cylinder 06.

By using a spring-actuated restraint device, the printing forme 01 is mounted in a defined, positionally precise, register-based manner.

The presence of a printing forme 01 can be detected automatically by the control device controlling the holding means 11. The assembly of the printing form 01, d. H. in particular its winding process, can be controlled by the control device mechanically and independently. The control device of the holding means 11 and the control device 18 of the valves 36 and the control device of the pressure bar 26 are preferably formed together in the press belonging to the control room.

The holding means arranged in the channel 07 of the forme cylinder 06 can be actuated separately for each printing forme 01. You are contactless z. B. switchable via magnets.

As an assembly aid for each printing plate 01 in the circumferential direction of the forme cylinder 06 only a single pressure element 14 is required, which z. B. can be configured as a on and off pressure roller 14. This allows a Andrückrollenleiste with several juxtaposed pressing elements 14 for several in Axial direction of the forme cylinder 06 juxtaposed printing plates 01 are structurally much simpler design.
