METHOD AND APPARATUS FOR JOINING HEAT SEALABLE MATERIAL

摘要

Apparatus (10) and a method for welding overlapping edge sections (20, 22) of heat sealable materials are disclosed. The apparatus generally includes a frame (12), a heating body (14) attached to the frame (12) for being positioned between the overlapping sheets to heat the sheets, an alignment control mechanism (16) for urging the overlapping sheets into a desired alignment relative to the overlapped sheet and a pressure roller for pressing the heated sections together to weld them together.
