Method for changing printing plates

摘要

A method and an apparatus for changing a printing plate on a printing press, include feeding the printing plate to a withdrawal chute of a plate changing apparatus by rotating the plate cylinder backward. Drivable transport rollers grip the printing plate and pull the latter out of a previously opened clamping device for the leading edge of the printing plate during the plate cylinder rotation, without the plate cylinder having to be stopped.

1. A method for changing a printing plate and carrying the printing plate away from a plate cylinder of a printing press, the method comprising the following steps:
initially opening a clamping device for a trailing edge of the printing plate mounted on the plate cylinder while rotating the plate cylinder backward; then opening a clamping device for a leading edge of the printing plate without stopping the plate cylinder; then gripping the printing plate after passing through driven transport rollers and carrying the printing plate away from the backwardly-rotating plate cylinder by the transport rollers without stopping the plate cylinder; and pushing the printing plate into a withdrawal chute by the backward rotation of the plate cylinder.
