Patent number: 10117787Abstract: Aspects of the present disclosure relate to tucking opposing side panels into a chassis of a diaper pant. The apparatuses and methods may utilize one or more conveyors that advance the chassis along a machine direction. Each conveyor may have a vacuum zone that applies a vacuum force to hold the chassis. The chassis may be positioned between a first conveyor having a first vacuum zone and a second conveyor having a second vacuum zone. The conveyors may apply opposing vacuum forces to hold the first waist region apart from the second waist region while the chassis advances in the machine direction toward a tucking device. The vacuum forces are then removed from the waist regions as the tucking device pushes the side panels toward each other. Pushing the side panels toward each other causes the inner surfaces of the waist regions to simultaneously move toward each other.Type: GrantFiled: March 30, 2015Date of Patent: November 6, 2018Assignee: The Procter & Gamble CompanyInventors: Gary Dean LaVon, Uwe Schneider, Joseph Hung Lam

Patent number: 10085896Abstract: The present disclosure relates to methods for manufacturing absorbent articles, and in particular, methods for making pre-fastened refastenable pant diapers. Aspects of the methods according to the present disclosure relate to the fabrication of refastenable pant diapers wherein discrete chassis are advanced in a machine direction such that the lateral axis is parallel with the machine direction. First side panels are then refastenably connected with the first waist region, and second side panels are permanently connected the second waist regions of the discrete chassis. The chassis are connected with discrete lengths of side panel material and/or connection zone material. The chassis are then folded, and the first and second side panels are subsequently bonded together. The article is then subjected to knife cut at or adjacent the bonded regions to create discrete, pre-fastened refastenable pant diapers.Type: GrantFiled: April 26, 2016Date of Patent: October 2, 2018Assignee: The Procter & Gamble CompanyInventors: Gary Dean LaVon, Joseph Hung Lam, Kazuaki Tameishi, Koichi Morimoto, Yoichiro Yamamoto, Norman Gorospe Juguilon

Patent number: 10071870Abstract: The present disclosure provides methods of winding substrates comprising three-dimensional features about a core to form a spool so that at least a majority of the three-dimensional features in one wrap of a lane of the spool are at least partially nested with a majority of the three-dimensional features in another adjacent wrap in the same lane of the spool. By at least partially nesting these three-dimensional features in adjacent wraps of a lane of the spool, the three-dimensional features may be at least mostly maintained in the substrates without significant compression during winding and storage of the spool.Type: GrantFiled: March 16, 2016Date of Patent: September 11, 2018Assignee: The Procter & Gamble CompanyInventors: Gueltekin Erdem, Nadezhda Kurbatova, Joseph Hung Lam, Sudhanshu Gupta

Publication number: 20170027769Abstract: Aspects of the methods according to the present disclosure relate to the fabrication of diaper pants wherein discrete chassis are advanced in a machine direction such that the longitudinal axis is parallel with the machine direction. Discrete lengths of elastic belt materials are then connected with the first waist region of a first advancing chassis and the second waist region of a second advancing chassis. The lengths of elastic belt materials are cut along the cross-direction between the discrete chassis forming a first elastic belt and a second elastic belt; the chassis are subsequently folded; and the first and second elastic belts disposed on the chassis are bonded together to create a discrete diaper pant. This apparatus and process configuration forms a continuous web of articles formed by intermittently spaced chassis and intermittently spaced elastic belts bridging the gap between the intermittently spaced chassis.Type: ApplicationFiled: October 14, 2016Publication date: February 2, 2017Inventors: Joseph Hung Lam, Gary Dean LaVon, Ronald Joseph Zink, II
