Abstract
A gripper device comprises a gripper carrier which reciprocates towards and away from an upsetting station in a multi-stage upsetting press and at least one gripper for carrying workpieces. Each gripper comprises a pair of guide elements on the carrier and a pair of gripper arms each pivotally connected to a respective one of the guide elements to be driven thereby. The gripper arms are pivoted to one another at a point which is triangularly spaced from the points at which the arms are pivoted to the guide elements. The guide elements are arranged so that as the arms open to deposit a workpiece, they are moved bodily upwards in order to clear the upsetting station, the upward motion being at a minimum as the arms start to open and increasing steadily as the motion proceeds.
