ABSTRACT:
A cutting-register feedback-control device of a cross-cutter of a rotary printing press for printing on a printing-carrier web, the cross-cutter including a driven cutting cylinder, and the rotary printing press having printing-unit cylinders, drawing devices for the printing-carrier web and positioning devices for adjusting the position of the printing-carrier web, the cutting-register feedback-control device including scanners for scanning markings on the printing-unit cylinders and for scanning the driven cutting cylinder, the scanners being connected to comparison and control circuits operatively connected with the positioning devices for the printing-carrier web so as to effect a correction in a position of the printing-carrier web if there should be an angular deviation between the printing-unit cylinders and the driven cutting cylinder, also being provided are rotary-position sensors, respectively, for the printing-unit cylinders, the drawing devices and the cutting cylinder, and a first control loop for a drive of the drawing devices, the rotary-position sensors for the printing-unit cylinders and for the drawing devices being connected in the first control loop, and a second control loop for a drive of the cutting cylinder formed independently of the first control loop, the rotary-position sensors for the printing-unit cylinders and for the cutting cylinder being connected in the second control loop.
