The present invention relates to an adjustment device for a lateral register of at least two adjacent flexible printing plates. Axially adjustable strips that accomplish the lateral registration are spaced circumferentially.
A lateral register adjustment device for printing plates is known from DE 42 41 588 C2. Printing plates have beveled edges which are fastened in a slit or in several slits extending in an axis-parallel direction along the circumference of the printing cylinder. Each one of the printing plates has a recess for this, which recess is engaged by a respective register pin which, in turn, is fixedly connected with one insertion strip, respectively. This insertion strip is movable in an axis-parallel direction in the slit. The insertion strips are arranged on top of each other in the slit and are each connected with a separate adjustment system.
The object of the present invention is based on providing an adjustment device for a lateral register.
In accordance with the present invention, this object is attained by the provision of printing plates whose beveled ends are received in a slit or channel in the printing cylinder. Each plate end has a register recess that will receive a register pin which is carried by an axially displaceable insertion strip. The insertion strips are situated one behind the other in the circumferential direction of the printing cylinder.
The advantages which can be achieved by means of the present invention rest, in particular, in that a lateral register adjustment device for printing plates with beveled edges has been created (slit clamping), whose insertion strips are secured against being ejected from the slit by simple means. Furthermore, the slit can be kept narrow, even if solid insertion strips are used. The beginning or leading end of each printing plate is provided with a lateral register adjustment device.
