摘要

Apparatus for assuring the in-register positioning of a cutting plate on a cutting cylinder, preferably a magnetic cylinder in a rotary printing machine. The apparatus comprises a contact plate which is arranged tangentially to the cutting cylinder. The contact plate is formed with a slot running axially parallel to the cylinder for the purpose of receiving the cutting plate, the slot having an edge which serves as a stop. An axially parallel measuring bar is positioned along the cylinder length and is parallel to the contact plate. Extending around the circumference of the cutting cylinder is a second measuring bar which crosses the first measuring bar.
