Patent number: 5749989Abstract: A method for producing a pant-style garment from a substrate having a plurality of tensioned garters. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment a substrate is joined to one or more mandrels having tensioned garters fitted thereon. Substrate material is removed from within the loop of the garter, thereby forming apertures in the substrate. The substrate is folded along its longitudinal centerline such that its longitudinal edges meet. The substrate is subsequently joined along lines of joinder, and the substrate is cut into individual pant-style garments. In preferable embodiments, a process for providing elastics to the longitudinal edges of the substrate, thereby producing elasticized waistbands is included.Type: GrantFiled: May 13, 1996Date of Patent: May 12, 1998Assignee: The Procter & Gamble CompanyInventors: E. Kelly Linman, Russell P. Bridges

Patent number: 5733401Abstract: A method for producing a pant-style garment from a substrate having a plurality of tensioned garters. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment a substrate is joined to one or more mandrels having tensioned garters fired thereon. Substrate material is removed from within the loop of the garter, thereby forming apertures in the substrate. The substrate is folded along its longitudinal centerline such that its longitudinal edges meet. The substrate is subsequently joined along lines of joinder, and the substrate is cut into individual pant-style garments.

Patent number: 5624420Abstract: Non-perforated tear lines for removal and evacuation of contents of disposable undergarments such as training pants. Non-perforated tear lines include a series of bond sites which are shaped, sized, spaced and arranged to provide a zone of weakness to permit severance of nonelasticized portions as well as elastic disposed in the waistband, the body of the pant, and the elastic leg bands for complete removal. Bond sites are formed by displacing a portion of material such that a thickened outer edge defines a weakened area of reduced thickness. Thus, elastic in the waistband may be disposed continuously 360 degrees around the wearer's waist, and elastic in the leg bands may be disposed continuously 360 degrees around the wearer's legs. In addition, improved pants having elasticized ear flaps in the body of the pants can be conveniently removed from the wearer.Type: GrantFiled: July 17, 1995Date of Patent: April 29, 1997Assignee: The Procter & Gamble CompanyInventors: Russell P.

Patent number: 5518566Abstract: A method and apparatus for forming a tensioned garter. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively clamped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. Once the garters are formed the mandrels may be rotated on their radial axes for alignment with downstream operations. Sealing through elastic members is avoided by interrupting the bonding of elastic members to an elasticized laminate at locations where ribbons are to be clamped. High compression of elastics where they are not sealed to the laminate causes elastic members to burst and contract. Elastic contraction leaves an area in which ribbons may then be bonded together without sealing through elastic members.Type: GrantFiled: October 5, 1994Date of Patent: May 21, 1996Assignee: The Procter & Gamble CompanyInventors: Russell P. Bridges, James R. Golan, Ronald H. Helton, Stephen J. Lange, Michael J. Madill, Michael G. Nease

Patent number: 5516392Abstract: A method for combining a tensioned garter with a substrate while holding the garter in a predetermined shape. A mandrel has a perimeter of the desired garter shape. An elastic garter is stretched and placed onto the mandrel such that an upper portion of the garter extends above a top surface of the mandrel while a lower portion of the garter clings to a side wall of the mandrel. The upper portion of the garter has sufficient elastic tension to cause it to fold over onto the top surface of the mandrel to form a garter flange. A substrate is then engaged with the garter flange and a sealing means seals the flange to the substrate, using the top surface of the mandrel as an anvil.Type: GrantFiled: October 13, 1994Date of Patent: May 14, 1996Assignee: The Procter & Gamble CompanyInventors: Russell P. Bridges, James R. Golan, Ronald H. Helton, Stephen J. Lange, Michael J. Madill, Michael G. Nease

Patent number: 5496429Abstract: A unitary disposable garment, such as disposable training pants, having a high degree of stretch in the cross-machine direction and fitting a broad range of wearer sizes. The unitary disposable garment is manufactured from a chassis and has a waist opening, two leg openings and a pair of side seams which join the front portion of the chassis to the rear portion of the chassis. The unitary disposable garment preferably has an absorbent assembly, i.e. an absorbent insert, secured to the inner layer of the chassis. The chassis from which the unitary disposable garment is manufactured, has four elasticized ear flaps; each ear flap is elasticized by securing an elastomeric element thereto and mechanically stretching the ear flap and the elastomeric element such that the ear flap is elastically extensible in the direction of initial stretching. The front portion of the chassis is then joined to the rear portion of the chassis on each side of the disposable garment by a seam.Type: GrantFiled: September 1, 1993Date of Patent: March 5, 1996Inventors: Margaret H. Hasse, Russell P. Bridges, Steven W. Miller

Patent number: 5393360Abstract: A method and apparatus for forming a tensioned garter and bonding it to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surface. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim.Type: GrantFiled: October 6, 1993Date of Patent: February 28, 1995Assignee: The Procter & Gamble CompanyInventors: Russell P.
