ABSTRACT A deep drawing machine for manufacturing containers from thermo- plastic 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 per- pendicular 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 communica- tion 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 corres- ponds to the banderole-shaped strip sections.
