Abstract

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.
