摘要： 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.

摘要： A web of fibers is continuously fed between a rotating tearing apparatus where the web is torn into sections without causing compression of the fibers at the tear line. The tearing apparatus is comprised of two opposed rotating pairs of web holding means or jaws which receive and engage the web. To tear the web, the leading jaw of each pair is angularly displaced away from the corresponding trailing jaw and then returned to a juxtaposed position relative to the trailing jaw. Preferably the jaws are provided with arcuate working surfaces which may be tipped with a resilient material to increase jaw life and to improve the holding characteristics thereof for webs of contoured cross section.
