Deep-drawing machine for manufacturing containers out of thermoplastic foil material having an arrangement for inserting into the hollow mold prior to the deep drawing step a banderole-shaped strip section. The machine includes support means for a roll of foil material, means for transporting the foil material, a heating arrangement as well as a forming arrangement and said forming arrangement consists of a stationary counter mold and the hollow mold movable perpendicular to the foil plane, which is pressed against a counter mold after the heating of the foil. After the container is formed by means of a pressure medium, the strip sections, which have been introduced into the hollow mold, are sealed onto the container. The arrangement for inserting the banderole-shaped strip sections into the hollow mold includes a winding mandrel which is stationary with respect to the axially movable hollow mold. In the outer peripheral surface of which winding mandrel there are disposed a plurality of bores which are adapted to be placed in communication with a vacuum source and there is arranged exteriorly of the hollow mold at the inlet side of the banderole-shaped strip sections a slider which is glidably mounted relative to the hollow mold and the winding mandrel. The slider includes a recess, the height of which corresponds to the width of the banderole-shaped strip sections.
In a deep-drawing machine for manufacturing containers out of thermoplastic foil material having an arrangement for inserting into the hollow mold prior to the deep drawing step a banderole-shaped strip section, whereby the machine includes support means for a roll of foil material, means for transporting the foil material, and a heating arrangement as well as a forming arrangement, said forming arrangement including a stationary counter mold and the hollow mold which is movable perpendicular to the plane of the foil, which is pressed against a counter mold after the heating of the foil, whereafter the container is formed by means of a pressure medium and thereby simultaneously the strip sections, which have been introduced into the hollow mold, are sealed onto the container, the improvement wherein the arrangement for inserting the banderole-shaped strip sections into the hollow mold includes a winding mandrel which is stationary with respect to the axially movable hollow mold, in the outer peripheral surface of which winding mandrel there are disposed a plurality of bores which are adapted to be placed in communication with a vacuum source, and there is arranged exteriorly of the hollow mold at the inlet side of the banderole-shaped strip sections a slider which is glidably mounted relative to the hollow mold and the winding mandrel, which slider includes a recess, the height of which corresponds to the width of the banderole-shaped strip sections.
