Abstract
The present invention relates to a seaming apparatus a method for producing a continuous sheet of thermoplastic material having a predetermined width from a plurality of elongated thermoplastic tapes each having edges defining a transverse width less than the predetermined width and each tape being wound on a roll. The seaming apparatus comprising a frame having a seaming zone. A feed device is mounted on the frame for rotatably supporting a plurality of rolls in a predetermined relationship. An alignment mechanism is mounted on the frame for receiving the tapes from rolls thereof supported by the feed device and for guiding the tapes into the seaming zones along paths defining a predetermined transversely adjacent relationship when the edges of the tapes position adjacent one another form a contiguous area. Thermal heating elements are provided in the seaming zone for thermally joining the contiguous area of the tapes to form the contiguous sheet of thermoplastic material. A take-up roll is rotatably mounting on the frame for receiving the continuous sheet of thermoplastic material from the seaming zone.
