    摘要: 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.

    摘要: A heater plate for butt fusion of polyolefin pipe has concentric rings, each with an array of radial bores containing cartridge heaters, and a concentric cavity between the rings to carry wiring from the cartridge heaters. The inner ring components are symmetrical to provide a foundation for uniform surface temperature distribution across the entire area of the inner ring. The outer ring components are coordinated to counterbalance the heat sinks resulting from their asymmetrical configuration so as to increase the likelihood that the uniform surface temperature distribution foundation established for the entire area of the inner ring can be maintained and so that the total diameter of the heater plate, including the outer ring, can be used in fusing pipe.
