Patent number: 6730069Abstract: A cloth-like, flexible mechanical fastener including a flexible layer and at least one fastener island, and methods of making the same. The fastener island has a planar perimeter edge, a mechanical fastening material, and a backing material attached to the mechanical fastening material. The backing material is embedded within the flexible layer and the planar perimeter edge is surrounded by the flexible layer. Accordingly, the mechanical fastener offers an improved flexibility and a cloth-like presentation. The improved flexibility and cloth-like presentation reduce the potential for the wearer to be exposed to coarse edges or creases, thereby lowering the possibility of red-marking or irritation of the skin. Moreover, the flexibility of the fastener allows the fastener to better accommodate the movement of the wearer, providing more reliable securement. The cloth-like, flexible mechanical fastener may be of particular use in combination with disposable absorbent articles to secure the article about a wearer.Type: GrantFiled: July 5, 2001Date of Patent: May 4, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Richard Warren Tanzer, Karen Marie Menard, Julius Charles Nagy

Publication number: 20020002358Abstract: A process for making prefastened and refastenable garments includes providing a plurality of discrete articles with mating fastening components disposed in the waist regions. First fastening components are separated from one another by an initial transverse distance. The waist region containing the first fastening components is modified to transversely displace these fastening components to a post displacement distance that is not equal to the initial distance. The process allows for convenient alignment of the fastening components to form refastenable seams.Type: ApplicationFiled: May 15, 2001Publication date: January 3, 2002Inventors: Debra Hartley Durrance, Scott Gerald Chapple, David Michael Clemens, Jason Gene Csida, Kurt Garrett Krupka, Heather Schenck Mortell, Robert Lee Popp, Marcille Faye Ruman, Scott John Andrew Swanson, Charles Robert Tomsovic

Publication number: 20010014798Abstract: The invention relates to a method of producing reclosable absorbent garments, in particular absorbent pants, and to the absorbent garments obtainable by said method. Starting from a continuous web (1) of absorbent articles attached side-by-side and with a line of weakening (6) arranged between adjacent articles, a first strip (8) comprising releasably attachable material is applied across the line (6) at one edge (25) of the web. A second strip of flexible material is also applied across the line (6) at the other edge (26) of the web. The web is then folded longitudinally to form a series of closed, joined adjacent articles. The adjacent articles are then partially separated at said line (6) but without rupturing said strips (8, 13), so as to provide a free zone (15) between said strips (8, 13) and the adjacent separated edges of each article. The strips (8, 13) are then joined together across the free zone (15) to form a plurality of joined garments.Type: ApplicationFiled: June 22, 1998Publication date: August 16, 2001Inventor: INGEMAR FERNFORS
