  • Publication number: 20130255861
    Abstract: The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, diapers, each including a chassis connected with front and back elastic belts. Opposing end regions of the chassis are connected with regions of the elastic belts where the elasticity of the elastic belts has been removed or deactivated. As discussed in more detail below, an elastic laminate is formed by intermittently bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. The elastic strands are then intermittently deactivated by severing the strands in the non-bonded regions to form deactivated regions of the elastic laminate. A plurality of chassis may then be bonded with the elastic laminate, wherein the first or second end regions of each chassis may be bonded with deactivated regions of the continuous elastic laminate.

  • Publication number: 20130255864
    Abstract: The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, diaper pants, each including a chassis connected with front and back elastic belts. As discussed in more detail below, opposing end regions of the chassis are connected with regions of the elastic belts where the elasticity of the elastic belts has been removed or deactivated. As discussed in more detail below, an elastic laminate may be formed by continuously bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. The elastic strands are then intermittently severed in light-bond regions of the elastic laminate. Adhesive on the laminate causes the severed elastic ends to retract or snap back from the light-bond regions at a relatively slower and/or controlled rate.

As discussed in more detail below, opposing end regions of the chassis are connected with regions of the elastic belts where the elasticity of the elastic belts has been removed or deactivated. An elastic laminate may be formed by continuously bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer such that the elastic strands are bonded to both the first substrate layer and the second substrate layer in heavy-bond regions. And the elastic strands are bonded to the first substrate layer and/or the second substrate layer with in light-bond regions. The elastic strands are then intermittently deactivated by cutting the strands into one or more discrete pieces in the light-bond regions. The discrete pieces retract and remain in the light-bond regions.

  • Patent number: 8541090
    Abstract: A method is presented for making a composite material from strips comprising longitudinal fibers and a binder or resin, which material comprises a number of layer assemblies one on top of the other. Each layer assembly comprises m sets (with m at least 2) of parallel strips each extending in a different direction, Each layer assembly is manufactured by successive steps of depositing groups of parallel strips according to a well defined pattern (without longitudinally interweaving strips with previously deposited strips). Before completing a layer assembly, with the exception of the last layer assembly, by depositing its last group of parallel strips, the first group of parallel strips of the following layer assembly is already deposited. A composite material manufactured with such a method is presented too.

  • Publication number: 20130240122
    Abstract: A method of manufacturing a disposable absorbent personal hygiene product including a stretched elastic strand and a flat nonwoven substrate includes mixing a pressurized gas and hot melt adhesive to form a foamed adhesive. A filament of foamed adhesive is discharged toward the stretched elastic strand and deposited onto the stretched elastic strand so that the foamed adhesive expands in volume on the stretched elastic strand. The stretched elastic strand is secured to the flat nonwoven substrate with the foamed adhesive. Alternatively, the foamed adhesive secures two flat nonwoven substrate portions of the disposable absorbent personal hygiene product together.

  • Publication number: 20130233470
    Abstract: A method for obtaining a composite material part from a preform of layers of fibers pre-impregnated with resin stacked on top of one another on a tool, the preform being delimited by a lower surface, an upper surface, and a peripheral flank. The method includes attaching to the tool, after the last layer has been laid, a peripheral part comprising a wing adapted to cover the peripheral edge of the upper surface, so as to create, in the periphery of the preform, a peripheral cavity adjacent to the flank of the preform and, before the polymerization phase, to withdraw the gas present in the peripheral cavity so as to tension filaments of the preform by exerting a traction force at the ends of the filaments.

  • Patent number: 8435372
    Abstract: A flexible container cover with an elastic gathering band around its edge is formed from a rectangular sheet of plastic film with recessed cut corners to form four flaps. The sheet is placed atop a mandrel having a rectangular flat top with eaves or undercut surfaces and four corner slots. Four hooks are positioned outside the slots so they underlie the cut-off corners of the sheet. An elastic band is stretched around the hooks and the flaps of the sheet. The hooks are moved inwardly into the slots to allow the segments of the band to pull and fold a middle portion of each flap inward. A set of tucker blades is then moved inward to push the folded portions of the flaps against side surfaces of the mandrel under the eaves. Four heat-sealing bars are moved up against the eaves to seal the flaps around the segments of the band to form hems.
