Abstract: A method of perforating a nonwoven web of fibrous fabric by directing the web through a nip defined by first and second moveable members. As the web moves through the nip it is penetrated by a plurality of heated pins projecting from the first member which enter heated apertures formed in the second member. The penetration of the pins causes the fibers of the fabric to separate and enter into the apertures and form openings through the web. The openings are surrounded by dense consolidated rings exhibiting greater hydrophilic properties than the nonperforated surface of the web.

Abstract: A method and apparatus for providing apertured elements such as reinforcing rings having precisely defined edges without tearing or distortion operates on an elongated strip of first and second sheet material held together by a detachable adhesive. Both perimeters of the desired apertured element are first cut in one sheet of the strip without cutting the other sheet. A second shape, within the inner perimeter of the apertured shape, is cut into the second sheet without cutting into the first sheet, either before or after the cuts in the opposite side. This leaves material within the apertured shape that is held in place by a border due to the adhesive backing. After first sheet material outside the apertured shape is separated from the second sheet, a mechanism is used to overcome the adhesive force at the border and remove the inner cuts simultaneously. Thus only the desired apertured elements are left on the second sheet to be removed for use either at that time or thereafter.
