Abstract
The deep-drawing of plastic foils for producing receptacles uses a drawing punch intermittently movable into a drawing mold and several expansion elements (jaws) radially movable on the drawing punch. The movement of the jaws and the punch is mutually effected to discontinuously move the drawing punch during its inward movement and to stop it for a respective predetermined dwell time. This can be combined with a continuous or discontinuous movement of the expansion jaw elements.
