Abstract
A press is provided with gripping rails for moving workpieces in work stations. The press is provided with a motor and a shaft moved thereby, on which shaft cams are mounted. Swing levers follow the shape of the cams, and connecting tabs direct the movements of swing levers toward driving movements of the gripping rails. At least two rollers are rotatably mounted on swing levers. The rollers run on the shaft cams. At least one of the two rollers is pressable with zero play against one of cams by a pretensioning device.
