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