METHOD AND DEVICE FOR WELDING PLASTIC MATERIAL

摘要

Welding surfaces of thermoplastics material together by depositing a continuous layer of molten thermoplastic welding material over adjacent areas of the surfaces to be joined, the deposition of at least part of the molten welding material being effected with a smearing action in which the material is subjected to shear forces acting across the surfaces, and allowing the deposited material to solidify.
