  • Patent number: 4218973
    Abstract: There is disclosed apparatus for printing plastic film including polyvinyl chloride stretchable film which comprises conventional multi-color printing apparatus with multiple cylinders, a transport web threaded through the printing cylinders and other rolls so that plastic film may be laid down on the transport web to be transported through the printing apparatus which also may include a drying section. Special arrangements are provided for laying the plastic film onto the transport web from a supply roll and for pulling it off on a take-up roll. At the supply roll, the rolled sheet is surface driven by a friction contact roll which is in turn driven by friction engagement with one of the rolls for the transport web. The take-up roll is driven by a direct mechanical linkage to the main drive shaft for the printing cylinders.
