  • Patent number: 4452580
    Abstract: 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.

  • Patent number: 4217163
    Abstract: In a hot forming machine in which molding means deform a thermoplastic foil band and cutting and stamping means further process the deformed foil band. A photocell is adapted to scan marking indicia on the foil band and to adjust a lengthwise adjustable connecting member in accordance with such scanning. The connecting member forms part of an advancing arrangement for the transported foil band. This advancing arrangement includes a swing arm pivotally mounted in the machine; a first shaft mounted on the swing arm in proximity of the free end thereof; and an eccentric rigidly secured to the first shaft and pivotally connected to the connecting member which is also pivotally connected to the swing arm.
