Publication number: 20160270984Abstract: A method is described for making an elasticized absorbent article having a waist opening and a pair of leg openings. First, multiple distributions of elastics are applied on a moving material sheet to form a moving web of an elastic composite. Then, each of a core section and a second material sheet is periodically applied onto the moving web to define a finished web of discrete elastic composite bodies. In subsequent steps, discrete absorbent pants articles are shaped from the finished web.Type: ApplicationFiled: November 19, 2015Publication date: September 22, 2016Inventors: PATRICK KING YU TSANG, ANNE SMID, ANDREW C.

Publication number: 20140180230Abstract: A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.Type: ApplicationFiled: December 19, 2013Publication date: June 26, 2014Applicant: DSG TECHNOLOGY HOLDINGS LIMITEDInventors: Patrick King Yu Tsang, Kuo-Shu Edward Chang, Andrew C.

Patent number: 8685190Abstract: A method is provided for making an elastic composite for incorporation into a disposable absorbent garment. An elastic element applicator is provided that is configured to move a section of a continuous strand of elastic element generally about a plane. A first web of material is conveyed in a first web moving direction such that the first web intersects the plane. Then, the applicator is operated to move the elastic element about the plane, thereby applying the section of elastic element onto the first web along a direction generally transverse to the web moving direction and such that the first web draws the continuous elastic strand from the elastic element applicator as the first web is conveyed away from the plane. The elastic element applicator may be in the form of a spin cylinder or bracket that is operated to spin the elastic element about the moving first web, thereby applying the elastic element on the first web.Type: GrantFiled: June 4, 2013Date of Patent: April 1, 2014Assignee: DSG Technology Holdings Ltd.Inventors: Kuo-Shu Edward Chang, Anne Smid, Patrick King Yu Tsang, Andrew C.

Patent number: 8529536Abstract: A method of making an elastic composite entails conveying a first sheet on a conveyor, and wrapping a section of elastic about the first sheet and the conveyor, thereby applying elastics cross directionally across the sheet. A second sheet is then applied onto the first sheet thereby creating a subcomposite including the two sheets and elastics sandwiched therebetween, wherein two elastics extend outward from one side of the subcomposite, about the conveyor, and return into an opposite side of the subcomposite. The subcomposite is cut through the first and second sheets and the elastics, thereby separating the subcomposite into a first carrier and a second carrier, each carrier including a material layer, whereby spaced apart elastics extend from the first carrier to the second carrier, the first and second carriers defining an exposed elastic region therebetween formed by the elastics.Type: GrantFiled: April 20, 2009Date of Patent: September 10, 2013Assignee: DSG Technology Holdings Ltd.Inventors: Patrick King Yu Tsang, Anne Smid, Andrew C.
