Summary:Apparatus for seizing and holding the trailing edge of a paper sheet for transfer and turn-over in a printing press. The sheet transfer cylinder is provided with a rotatable central shaft and a plurality of segment members arranged in spaced planes radial to the shaft in at least one set to provide a cylindrical circumferential surface for the paper. The apparatus comprises a first elongated rod extending through the segments of the set and journalled for rotation about its longitudinal axis, brackets fixed to the rod and extending toward the circumferential surface, and a second elongated rod journalled in the brackets for rotation about its longitudinal axis exterior of the segments. Gripper elements are carried by the second rod, and a counter-ledge or bar is carried by the brackets. The gripper elements are adapted to cooperate by mechanical action with the bar to seize the paper sheet on movement of the second rod.
