Abstract
An apparatus for lap sealing plastics resin films is disclosed. The apparatus includes a heated and driven belt and a back-up plate. The belt may be driven independently of the film, such that its speed need not equal that of the film. The back-up plate includes a finger means for orienting the film into a lapped position and a sealing surface which permits the film to slide without damage and which does not act as a heat sink.
