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