Abstract

Tape tab fasteners are cut from a web stock, which includes a substrate coated on one surface with a pressure-sensitive adhesive and a release sheet positioned on the adhesive coating, and are applied transversely at predetermined intervals along the edge of a moving web of material, such as a web of plastic material suitable as an impervious barrier layer in disposable diapers. The web stock is drawn along a concave guide and a finger, positioned transversely between the substrate and release sheets, separates a predetermined width portion of the release sheet from the adhesive along one side of the web. The separated portion of the release sheet is folded over the remainder thereof. Tape tab fasteners of predetermined width are cut transversely from the end of the web stock and attached to the side edges of the moving web stock.
