ABSTRACT:
An apparatus for making head pieces for containers with a membrane of laminate having a metallic barrier layer, is designed to make one-piece head pieces, of a thermoplastic material with a mouthpiece neck, a cone-like breast part next to it, a ring-shoulder next to the breast part, a ready-made round plate and a membrane of a laminate with a metallic barrier layer. From a tape of laminate with a metallic barrier layer, using a deep drawing operation, the round plate is produced in a form representative of the outline of the head piece to be produced, is stamped out and is then run down into a mold. At the same time as the lowering the membrane is stamped out of the center part and is kept in position. After this thermoplastic material is placed in the mold and then the membrane is lowered into its last position in the mold and at the same time as the lowering of the membrane pressing of the thermoplastic material in the mold takes place.
