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.

Method for changing printing plates

A method and an apparatus for automatically feeding printing plates to a rotary printing press include conveying devices spaced apart from each other transversely to a conveying direction for feeding the printing plate to a clamping device having register pins. One of the conveying devices is lifted briefly off the printing plate in the event of a lack of in-register contact while the other conveying device remains in contact with the printing plate and thus ensures a forward drive of the printing plate, while the lifting of one conveying device promotes stress relief in the printing plate. A sheetfed rotary printing press having the apparatus, is also provided.

Method and apparatus for automatically feeding printing plates and printing press having the apparatus

A method and an apparatus for feeding printing plates to a plate cylinder of a printing press, load the printing plate in the vicinity of its front edge with a curvature which extends convexly with regard to the plate cylinder axis.
