ABSTRACT:
Apparatus is provided for automatically applying a lid comprised of a film of thermoplastic sheet material to the top of a cup. The film is supplied in a roll and the leading end is fed into a position between the top of the cup and a heat sealing head. In an operating cycle of the apparatus, the cup is brought up against the film and the heat sealing head is brought down on top of the film to seal the film to the cup and sever the forward section of the film from the roll. A film stabilizer is provided on the film feed mechanism for maintaining control of the film and a pneumatic circuit provides an automatic control of the functional components in predetermined timed sequence.
