ABSTRACT:
An improved process and heating arrangement for actuating and arresting a heat-forming machine for producing deep drawn containers made of thermoplastic foil band material. The foil band material is paid out in stepwise fashion from one or more storage rollers and is then processed along a process path along which there are arranged in downstream fashion: a heating arrangement, a molding arrangement, a filling arrangement, a stamping arrangement and a driving mechanism. Control circuit means are operatively connected to all of the afore-recited arrangements. The heating arrangements includes heating elements for heating the foil band material to the molding temperature. Screening plates are slidably mounted in the heating arrangement between the foil band material and the heating elements. The control circuit means first cause the screening plates to move in a direction opposite to the feed direction of the foil band material out of the heating arrangement to thereby expose a predetermined portion of the foil band material to heating until it has reached a forming temperature. The foil band material is then moved in stepwise fashion via the control circuit means and driving mechanism through the afore-recited arrangements; the actuation of the arrangements and timing of the movement being controlled by the control circuit means.
