ABSTRACT:
A gripper mechanism for seizing the trailing edges of paper sheets on a transfer drum of a printing machine. A plurality of rollers are resiliently mounted so as to be rotationally shiftable toward the direction of movement of the paper sheet. The rollers are oriented at various oblique angles with respect to the movement direction, with rollers further from the middle axis of the transfer drum being oriented at a greater oblique angle than rollers closer to said axis.
