Abstract
A pregripper configuration in a sheet-fed rotary printing press feeds single sheets to a rotating cylinder. A cam drive includes a main cam and a roller lever which pivots about a frame-fixed shaft. A lever mechanism, which is articulated to the roller lever and a pregripper pivot arm, transmits the motion of the cam-following roller lever to the pivot arm. The pivot arm is also pivoted about a frame-fixed shaft. In order to compensate for play in the lever mechanism, a pretensioned spring is disposed between an attachment point on the roller lever and an attachment point on the pivot arm. In one embodiment, the pretensioned spring extends approximately parallel to a rigid link connected in articulated fashion between the roller lever and the pivot arm. In another embodiment, the spring is attached to a compensating cam drive.
