ABSTRACT:
Method and device for sealing thermoplastic material. A support plate (16) supports sheets (29, 31) of the thermoplastic material, and a heat element (18) is provided adjacent thereto. A pressure plate (20) mates with the support plate and includes recess means (24) for receiving the heat element means. A confined melt zone (35) is formed between the heat element and the pressure plate (or the recess means) when they are in mating relationship. The confined melt zone serves to confine the melted thermoplastic material to form a good seal by relieving stress between the seal and the seal-material interface. The heat element and recess means are manufactured as interchangeable dies in different sizes and shapes for different materials. The heat element may be formed into different shapes, such as a glove for manufacturing gloves.
