  • Publication number: 20150101739
    Abstract: 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.

  • Patent number: 8993099
    Abstract: A stretch laminate having a first nonwoven material, a second nonwoven material, an elastic film. The elastic film may be interposed between said first and second nonwoven material. The elastic film has a first longitudinal side edge and a second longitudinal side edge. The stretch laminate further has a first plane of adhesive having differing amounts of adhesive as measured laterally within the stretch laminate. The differing amounts of adhesive being controllable. The first plane of adhesive being interposed between the first nonwoven material and the elastic film. The stretch laminate further has a second plane of adhesive having differing amounts of adhesive as measured laterally within the stretch laminate. The differing amounts of adhesive being controllable. The second plane of adhesive being interposed between the second nonwoven material and the elastic film. Each of the above elements are substantially laminated together to form a laminate. The laminate is activated to form the stretch laminate.

  • Publication number: 20140378287
    Abstract: Aspects of the present disclosure relate to tucking opposing side panels into a chassis of a pant diaper. 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 tucking device may discharge air to push the side panels into the chassis and create longitudinal fold lines along edges of the absorbent core of the diaper.

  • Publication number: 20120065043
    Abstract: 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.

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.

  • Publication number: 20040225273
    Abstract: The present invention pertains to a porous, macroscopically-expanded, three-dimensional, elastomeric web suitable for use in elasticized portions of disposable absorbent articles such as bandages, diapers and pull-up diaper training pants. In a preferred embodiment the web has a continuous first surface and a discontinuous second surface remote from first surface. An elastomeric web of the present invention preferably comprises a formed film having at least two polymeric layers, with at least one of the layers being an elastomer and at least one of the other layers being a substantially less elastomeric skin layer. In a preferred embodiment the elastomeric web exhibits a multiplicity of primary apertures in the first surface of the web, the primary apertures being defined in the plane of the first surface by a continuous network of interconnecting members. Each interconnecting member exhibits an upwardly concave-shaped cross-section along its length.
