ABSTRACT:
Apparatus for producing a breathable high strength, paper-plastic film laminate fabric sheeting, capable of being cut and sewn to form medical gowns and other garments. In this apparatus, a web of metallized paper and a web of oriented synthetic plastic film whose inner surface is corona-discharge treated before being coated with a water-based adhesive are concurrently fed in superposed relation into combining rolls to effect cold lamination of the webs to yield a laminate sheeting in which the orientation of the film web is unimpaired. The laminate sheeting emerging from the combining rolls is then foraminated to render the sheeting permeable only to moisture vapor whereby the foraminated sheeting has fabric properties and can be tailored to form garments. To enhance these fabric properties, the foraminated sheeting is embossed to impart greater bulk thereto.
