Plate inserting apparatus in rotary printing press

Abstract

A plate inserting apparatus in a rotary printing press for inserting a plate into a plate fixing unit of a plate cylinder includes a plate holder, a cover, and a first reference pin. The plate holder moves between a first position where the plate holder holds the plate and a second position where the held plate is inserted into the plate fixing unit of the plate cylinder. The cover selectively opens and closes a plate insertion side of the plate cylinder. The first reference pin is fixed to the cover to position the plate before held by the plate holder when the plate holder is located at the first position.
