ABSTRACT:
A press having a drawing apparatus has a sheet metal part that is drawn in the drawing stage. This sheet metal part is to be taken over by a transfer device in a stage of the upward movement of the drawing apparatus that is as early as possible in order to utilize the long time period of the upward movement of the slide for the transfer movement. After the drawing, passing through the lower dead center of the slide movement and the drawing apparatus movement, the sheet metal holder is temporarily stopped in a removal position and is therefore temporarily prevented from continuing to move upward.
