METHOD FOR FORMING A COMPOSITE ELASTIC MATERIAL

摘要

A method for forming a composite elastic material. A thermoplastic film (130) is extruded from an extruder (132). The thermoplastic film (130) is fed while still in a molten condition onto a rotating forming structure (115) exhibiting a multiplicity of apertures therein. A pneumatic vacuum is applied to the thermoplastic film (130) to produce apertures in the thermoplastic film. An elastic member (100) having at least one elastic strand is placed against a surface of the thermoplastic film (130) while the thermoplastic film (130) is still in a molten condition.
