Apparatus and methods for producing folded edges in a film in-process, and compositions of such film are provided. A method of folding edges includes: separating a first idler roll and a second idler roll by a first distance; positioning a plurality of folding guides between the first idler roll and the second idler roll; separating adjacent sections of film having a majority layer comprising a Ziegler Natta catalyzed linear low density polyethylene copolymer resin having molecules that inherently lack long chain branching, wherein a majority of said molecules are oriented in a substantially longitudinal direction due to an induced strain, and inducing two folds with each folding guide, thereby causing an edge of each section of film to turn under 180 and cling to a bottom surface of the section of film; and moving the adjacent sections of film from the folding guides to the second idler roll.

Method of making prefastened refastenable disposable absorbent articles

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.

Discontinuously laminated film structures with improved visual characteristics

In one example embodiment, a laminated film includes an extruded ribbed first film portion that includes multiple ribs, where consecutive ribs are separated by webs that are integral with the ribs. The laminated film also includes an un-ribbed second film portion, and a region of discontinuous lamination between the first film portion and the second film portion. The region of discontinuous lamination includes multiple regions where the first and second film portions are bonded together, and multiple regions where the first and second film portions are not bonded together.

LEG AND FLAP ELASTIC COMPOSITE FOR AN ABSORBENT ARTICLE AND METHOD OF MANUFACTURING SAME

An absorbent article having a front waist region, a back waist region, and a crotch region extending between and interconnecting the front and back waist regions. The article comprises an outer cover, a body-side liner, an absorbent assembly between the outer cover and the body-side liner, and leg and flap elastic composites including a containment flap portion and a gasket portion. Each of the composites are attached to the liner such that one of the composites is disposed adjacent one side edge of the liner and the other composite is disposed adjacent the other side edge of the liner, each of the composites extend longitudinally from the front waist region to the back waist region, and each of the composites have a deadened portion in the front waist region or the back waist region. The article further includes a waist elastic member extending longitudinally between the deadened portions.

Flexible containers and methods of forming the same

A method for sealing and cutting of a flexible material for forming a flexible container comprising a product volume and at least one structural support volume can include feeding at least two flexible material into a sealing apparatus comprising a sealing surface and an opposed anvil surface; contacting a seam region of the at least two flexible material with the sealing surface to form a seal in the seam region and cut the seal to form a seam in a single unit operation. The seal defines one or both of at least a portion of a boundary of the product volume and at least a portion of a boundary of the at least one structural support volume.

Leg and flap elastic composite for an absorbent article and method of manufacturing same

A method of manufacturing a liner/composite web for use in an absorbent article includes joining a leg elastic member to a web moving in a machine direction and joining a flap elastic member to the web. The flap elastic member is spaced from the leg elastic member. The web is folded to form a leg and flap elastics composite including an outer side edge. The web is joined to a substrate to form the liner/composite web. The liner/composite web is joined to a web of material such that the outer side edge of the leg and flap elastics composite is coterminous with one of a pair of laterally opposing side edges of the web of material.

Multilayered material sheet and process for its preparation

The invention relates to ballistic resistant article having a multilayered material sheet which includes a consolidated stack of unidirectional monolayers of drawn polymer, whereby the draw direction of two subsequent monolayers in the stack differs. At least one monolayer comprises a plurality of unidirectional tapes of the drawn polymer, aligned in the same direction, whereby adjacent tapes do not overlap. The invention also relates to a process for the preparation of the multilayered material sheet, and to a ballistic resistant article comprising the multilayered material sheet.

Making Z-fold multi-element substrate structure

A method of making a folded micro-wire substrate structure includes providing a transparent flexible substrate having a first side and a second side opposed to the first side. The flexible substrate has a first portion and a second portion adjacent to the first portion of the flexible substrate. One or more electrical conductors and one or more electrical components are formed on or in the flexible substrate. At least one optical element is formed on or in the flexible substrate in the second portion. The flexible substrate is folded with a first fold between the first and second portions so that the first portion is aligned with the second portion in a perpendicular direction and the optical element directs light to or from the electrical component.

Dispensable face mask and method of making the same

A method of making a face mask is disclosed. The method includes providing an elastic nonwoven web continuous in a machine direction, the elastic nonwoven web having a central lane extending in the machine direction; bonding a filtering web to the central lane of the elastic nonwoven web to provide a layered web, the filtering web being continuous in the machine direction and having a cross-web width that is substantially the same as the cross-web width of the central lane; and stamping a face mask into the layered web. A face mask and a continuous layered web having a plurality of face masks disposed thereon are also disclosed.
