Patent number: 5628856Abstract: A method for forming a composite elastic material. An elastic member having at least one elastic strand is fed onto a rotating forming structure exhibiting a multiplicity of apertures therein. The elastic member has a surface facing the forming structure and another surface facing away from the forming structure.

Patent number: 5603794Abstract: A method for the manufacture of angled tape tabs for use with disposable absorbent articles. The first step is to provide an adhesive coated substrate having a first centerline and a second centerline perpendicular to the first centerline. A release substrate having a release surface and an adhesive surface is contacted with the adhesive coated substrate and partially covers the adhesive coated substrate to form a laminate. The laminate is then cut at an angle to the first centerline to form individual angled tape tabs. Each angled tape tab has a fixed end and a refastenable end. The fixed end of the angled tape tab is then secured to an absorbent article.Type: GrantFiled: February 22, 1996Date of Patent: February 18, 1997Assignee: The Procter & Gamble CompanyInventor: Suzanne M.

Patent number: 5549777Abstract: The present invention provides a three-dimensional, macroscopically expanded, apertured, laminate web suitable for use as a topsheet on an absorbent article and a method for making the same. The web includes a first layer of substantially transparent, polymeric material having an inner surface and an outer surface. A nonwoven web is secured to the inner surface of the substantially transparent polymeric material and is visible through the substantially transparent polymeric material. The presence of the nonwoven web creates the appearance of a fibrous web which is perceived as soft and skin friendly while still maintaining the fluid transport benefits of prior art plastic webs.Type: GrantFiled: June 5, 1995Date of Patent: August 27, 1996Assignee: The Procter & Gamble CompanyInventors: Fred M.

Patent number: 5531729Abstract: In an absorbent article, such as a diaper or incontinence briefs, an elastic member comprising a net-like elastic substrate to which fibers are pre-bonded provides for a breathable elastic for use as a side- a waist- or leg elastic. The fibers that are bonded to the net-like substrate, for instance by hydro-entangling, ensure a soft and comfortable contact with the wearer's skin. In the side panels of the absorbent article, the elastic members have a large freedom of stretch without buckling taking place, thus reducing chances of leakage. When the elastic member is located between the topsheet and the backsheet, a strong connection of topsheet to backsheet is established using a relatively small amount of adhesive. When the topsheet is physically deformed to impart stretchability, the fibers of the elastic member form a soft and resilient layer and prevent direct contact of the elastic member and the user's skin in case of thinning of the topsheet.Type: GrantFiled: September 22, 1994Date of Patent: July 2, 1996Assignee: The Procter & Gamble CompanyInventors: Peter Coles, Attila Tamer
