Title: Sheet transfer apparatus for rotary printing machines having serially arranged printing stations

Abstract: To permit reversal of sheets having extended length, a sheet storage or sheet transfer drum in engagement with a sheet reversal drum is formed with a sheet displacement apparatus located on the sheet storage drum rearwardly--with respect to the direction of rotation thereof--of the gripper means of the sheet storage drum and operable to lift a sheet off the circumference of the storage drum; the sheet displacement means preferably is a rail extending axially across the width of the storage drum which can swing from a circumferential position on the storage drum to an extended position, under control of a fixed cam thus, effectively, shortening the length of the overlap of a sheet on the storage drum on the circumference thereof and permitting handling of longer sheets thereby. The extension of the sheet displacement means is carried out at a position when the displacement means are out of engagement or interference with any adjacent cylinder.
