Device for controlling the green run of printing cylinders when printing stiff metal strips in register or the like.

Device for controlling the G-Ieichlaufs or several independently driven printing cylinders when printing stiff metal strips in register or similar.

The printing and in particular the lithographic printing of continuous webs of metal and Similar stiff materials causes serious problems when printing on webs made of relatively pliable Material, such as paper, metal foil or textiles, do not occur.

The main problem lies in the synchronization of the Rotation of the pressure bearing the image to be reproduced

The increase in length of time can bring the print images of the wide series back into the controller, this takes place after a considerable number of print images of the wide series has been generated.

With regard to the above, the The main object of the present invention is to provide a synchronization control of the type mentioned in the introduction create that is simple, works economically and controls the rotation of the image cylinder in such a way that dme this is synchronized with the belt speed remains, with the angular adjustment of the cylinder regardless of temporary or local Changes in speed of the belt part just passing through the printing station always have the correct relationship to the just "acted upon belt part receives, so that all subsequent print images of the cylinder via the entire length of the tape in longitudinal register to each other.

To solve the aforementioned problem, the aforementioned synchronization control is characterized by a per se known, the surface of the moving tape acting on the feeler roller, which is arranged near the printing cylinder and drives a first position-dependent electrical signal transmitter, the output of which is together with the output of a second position-dependent electrical signal transmitter coupled to the pressure cylinder forms a differential signal for an electrical servo device which adjusts a control gear provided between the pressure cylinder drive and the pressure cylinder.

Each picture frame is driven by a Synohron-Klektremotor 20 or another drive with a constant speed via Hegel gear 22 so that the picture frame rotates independently of the belt.
