Abstract
Press apparatus including a blank holding ram and a drawing ram which are reciprocally driven such that the holding ram can hold a blank of material while the drawing ram moves relatively to the holding ram to perform a drawing operation on the blank. Stops are provided for limiting the movement of the holding ram with pressure fluid cushions being arranged in the drive train for the holding ram so as to accommodate a dwell phase with the holding rams against the stops during the drawing operation.
