It is understood that preferably each of the plate cylinders 07 of the printing press 01 can be associated with a corresponding register device 21.

Particularly in multicolor printing, it is important for the quality of a printed product to be produced that printing forms 14 in the printing process of successive printing units 04 of a printing press 01 are arranged in register on their respective forme cylinder 07 in order to print from one another, printed by different printing units 04, but to the same print image belonging color separations of the printed product on the substrate 05 accurately print each other to print. To a register, in particular page register containing alignment and feeding of printing plates 14 to allow their respective forme cylinder 07, the participating in the printing process, z. For example, printing forms 14 to be used in an offset printing method are trimmed along at least one edge, preferably along two of their edges, parallel to the two parallel lines of the type area mirror so that at least this one edge is always aligned parallel to the type area. If it is ensured that the printing plate 14 exactly parallel to the transport direction of the printing image receiving substrate 05 a forme cylinder 07 of the printing press 01 and mounted on the forme cylinder 07, the form cylinder 07 for the register setting of the printing plate 14 corresponding adjustment devices, eg. B. register pins o. Ä., No longer needed.

The means 14 laterally trimmed by means as described above is supplied with its at least one cropped edge of the forme cylinder 07 of the printing press 01, aligned during the feeding for a register-containing positioning laterally to this forme cylinder 07 and mounted there on the forme cylinder 07. In addition to the positionally accurate arrangement causes the lateral alignment of the printing plate 14 also that the trimmed edge of the printing plate 14 and thus the lines parallel to this edge lines of its type mirror are aligned orthogonal to the axis of the forme cylinder 07.

The positionally accurate feeding in the axial direction of a printing forme 14 to the forme cylinder 07 takes place for. B. on a plate changing device 20 (see. Fig. 2 ) or from a plate magazine 20, preferably in such a way that a beveled end 16 of the printing plate 14 can be inserted in a longitudinal direction of the forme cylinder 07 extending below the lateral surface channel 17, wherein the channel 17 on the lateral surface of the forme cylinder 07 a z. B. slot-shaped opening, cf. Fig. 3 , In the channel 17, a holding device not shown here can be arranged in a conventional manner, the z. B. may be formed as a remotely controllable clamping device.

Another auxiliary device for mounting or removing the printing plate 14 may be associated with Fig. 2 be discussed roller bar 18, cf. also Fig. 3 ,

Thus, the printing plate 14 with respect to the axial direction of the forme cylinder 07 in the correct position, d. H. in an orthogonal to the axial direction of the forme cylinder 07 alignment, is supplied and optionally fixed, outside of the forme cylinder 07 is a device 21 for laterally aligning and guiding the printing plate 14 produced in register, above and below also called functional unit 21, in particular register device 21, arranged.

The register device 21 has z. B. a to the axis of the forme cylinder 07, that is, in the longitudinal direction, substantially parallel cross member 22 and a register cross member 22 and register carrier 22, the or the at least one, preferably a plurality of register stops 23; 24 carries. At least part of the functional elements 23; 24, for example register stops 23; 24 is movable on the register carrier 22 between a functional position in which it projects into the plane of the movement path of a printing form 14, and a rest position in which it does not protrude into the plane of the movement path of a printing plate 14. In the rest position, the register stops 23; 24 arranged at least substantially within the housing 22 defining a register carrier 22, while they are folded out in its operating position from the housing 22 and protrude into the plane of movement of the printing plates 14. In the Fig. 5 to 7 is in each case the functional position of the register stops 23; 24 shown.

To move the register stops 23; 24 these are in the case of in the Fig. 6 illustrated embodiment each held on a register carrier 22 via a respective pivot axis 25 pivotally mounted holder 26, which in turn cooperates with a disposed within the register carrier 22 cylinder piston means 27 which preferably operates pneumatically and remotely controllable, z. From the Control station of the printing press 01 can be controlled remotely. A carrier 30 of the housing 22 for receiving the pivot axes 25 of the holder 26 has exactly drilled pivot points and index holes.

For an adjustment of the register stops 23; 24, depending on certain operating conditions, such as fan-out effects, the position of the register stops 23; 24 are adjusted on the holder 26 in the longitudinal direction of the register carrier 22 by means of an adjusting device 28 within a defined setting range.

The register stops 23; 24 are collapsed, for example, for an operating situation in which no printing form change should take place and pivoted when a printing plate 14 is supplied. Over the length of the forme cylinder 07, which is substantially the width of z. B. four printed pages, z. B. newspaper pages corresponds, in such a case, four pairs of register stops 23; 24 (one each for each of the four printing plates 14), each printing plate 14 being aligned and guided between a respective register stop 23 and a register stop 24.

In order to effectively avoid jamming of the supplied printing forme 14 while it is being fed to the forme cylinder 07, one of the two register stops 23, each associated with a printing forme 14, is; 24, in the case of the embodiment of the respective register stop 24, resiliently formed. This can be done in any way, for example, either by using a resilient material for the register stop 24 or by a resilient mounting of the register stop 24. Thus, at least one of the forme cylinder 07 to be supplied to the printing plate 14, but preferably each of the forme cylinder 07 to be supplied to the printing plate 14 laterally each between a in the axial direction of the forme cylinder 07 rigid (but possibly adjustable) register stop 23 and a resilient (and possibly also adjustable) register stop 24 out.

From the illustration to Fig. 6 It is clear that in principle arbitrarily wide register crossbars 22 from the same sub-assemblies, ie here register stop devices 29 and functional units 29, can be composed. In Fig. 6 For example, a four-page-wide register device 21 is shown, wherein in the illustration rightmost a rigid register stop 23 may be located, which can not be formed wegklappbar, and the leftmost register stop means 29 can only carry a resilient, swing-stop register stop 24 , By folding away certain register stop devices 29, different formats can be processed, for example, by folding away the first and third register stop devices 29, seen from the left, for printing panorama pages, printing plates 14 can be mounted in panorama format.

For controlling the movement of the functional elements 23; 24, ie here the register stops 23; 24 or for controlling the functional units 21, ie here the register devices 21 are a plurality of controllable valves 33; 34; 36; 37, which are preferably not permanently, but only temporarily connected via a single compressed air supply 39 or supply line 39, ie a line 39 with an external compressed air source 41, cf.
