Abstract
An improved heating method and heating nozzle useful in the forming of a two-piece thermoplastic foam cup assembled from two thermoplastic foam pieces on a cup-forming turret machine. The method and apparatus of the invention prevent premature sticking of the foam bottom piece to the foam sidewall piece and result in better sealing of the foam bottom to the sidewall.
