Abstract
Device for avoiding registration errors at an oscillating pregripper of a sheet-processing machine includes a gripper bar deflectable in synchronism with the machine so that a respective sheet being processed therein undergoes stretching in a trailing region of the sheet. The gripper bar, in a middle region thereof, is guided and driven in a flexurally bending-resistant manner. A feeder cylinder carries thrust pads at both sides thereof for deflecting the gripper bar at the ends thereof in a sheet travel direction before a respective transfer of a sheet at the feeder cylinder, and for maintaining the deflection until sheet transfer has been completed.
