<p>A deep drawing machine for manufacturing containers from thermoplastic foil material has an arrangement for inserting banderole-shaped strip section into the hollow mold prior to the deep drawing step. The machine includes support means for a roll of foil material, means for transporting the foil material, a heating arrangement and a forming arrangement. The forming arrangement has a stationary counter mold, the hollow mold being movable perpendicular to the foil plane and being pressed against the counter mold after the heating of the foil. The container is then formed by means of a pressure medium and the strip sections, which have been introduced into the hollow mold, are simultaneously sealed onto the container. The arrangement for inserting the banderole-shaped strip sections (10) into the hollow mold (11) includes a winding mandrel (12) which is stationary with respect to the axially movable hollow mold (11), in the outer peripheral surface of which winding mandrel there are disposed a plurality of bores (14) adapted to be placed in communication with a vacuum source (13). Arranged exteriorly from the hollow mold (11) at the inlet side of the banderole-shaped strip sections (10) is a slider (16) which is glidably mounted relative to the hollow mold (11) and the winding mandrel (12). The slider includes a recess (17), the height of which corresponds to the banderole-shaped strip sections.</p> |
