An elastic diaper part has an inelastic substrate layer having a wide inner end for connection to a diaper and a narrow and opposite outer end spaced in a stretch direction from the inner end, narrower than the inner end, and adapted for connection to a closure. An elastic film is juxtaposed and generally contiguous with the substrate layer, and there is an array of parallel adhesive strips extending transversely of the direction between the substrate layer and the elastic film. Each strip adheres the film to the substrate layer, and the strips are each of a respective strip width and separated by spaces each of a respective spacing width. The strip and/or spacing width varies from the inner end to the outer end such that the diaper part stretches uniformly between its inner and outer ends when stretched in the direction.

Elastic strap part for diaper closure

An incontinence brief for an adult wearer has an absorbent body having a fluid-permeable inner side, a fluid-tight outer side, and an absorbent liner therebetween. The body is subdivided into a central part adapted to fit in a crotch region of the wearer, a rear part connected to the central part and adapted to fit against a rear waist region of the wearer, and a front part adapted to fit against a front waist region of the wearer. Two fastening straps adapted to fit around respective sides of a waist of the wearer each have a rear end secured to the rear part and a front part. At least one of the fasteners is provided between its respective front and rear ends with an elastic layer forming an elastically stretchable region, and each of the fasteners has an outer layer formed by a water-jet consolidated fleece.

Incontinence brief

A nozzle for applying a liquid adhesive to a web moving continuously in a travel direction has a body having a passage forming an outlet opening generally transversely to the direction immediately adjacent the moving web at a face of the body so that the liquid adhesive flows through the passage and out the outlet end onto the moving web. Structure on the face of the body forms immediately upstream of the outlet a porous region. Air is fed through the structure and out of the face to form between the region and the web an air cushion.

Elastically stretchable diaper closure elements that each comprise an inelastic and reinforced attachment region for securing a closure component and an adjacent elastic stretch region can be punched from a textile web. A plurality of pairs of elastic film strips of an elastically stretchable polymer are inserted between two cover layers of nonwoven with the film strips parallel and spaced laterally from one another. Between each pair of elastic film strips a strip of a reinforcement film is inserted that has a support layer and an outer layer of polyethylene on at least one side between the cover layers with each reinforcement-film strip overlapping each of the respective elastic film strips at a respective overlap region. The reinforcement-film strips are bonded to the elastic film strips in the overlap regions, and the nonwoven cover layers are bonded to the reinforcement film strips by ultrasonic or thermal welding.

Method of making a web from which elastic diaper closures can be stamped

A laminate for making a flexible fastener. The laminate has according to the invention outer layers of nonwoven and parallel and spaced strips of an elastic film laminated between the outer layers. The outer layers are directly bonded to each other in regions between the elastic strips and there form inelastic regions of the laminate while regions each containing one of the strips form elastic regions. At least one of the outer layers is a sheer nonwoven. A color or pattern imprint is printed on the one outer layer over the elastic and inelastic regions.

Laminate

A method for the production of an elastic composite material with a textile surface. First, a laminate is produced, which has elastic cover layers and a core composed of a nonwoven fabric. Subsequently, the laminate is separated into two strips, each of which has a cover layer and an adhering layer of nonwoven fabric, by tearing open the core.

Method for the production of an elastic composite material with a textile surface

A method for the production of an elastic laminate material web comprises laminating a cover material onto a carrier film consisting of a thermoplastic elastomer, using a hot-melt glue. The carrier film is rolled off a film roll and has a polymer powder on at least one side, to prevent interlocking of the layers of the carrier film in the film roll. The melt temperature of the powder is less than or equal to the gluing temperature of the hot-melt glue, so that the powder melts during lamination.

Method for the production of an elastic laminate material web

A laminated web from which diaper closure elements may be punched is made by first applying at least two pairs longitudinally extending and transversely spaced bend-resistant strips to a first longitudinally extending nonwoven tape. Then a respective longitudinally extending strip of an elastically stretchable polymer is applied to the first nonwoven tape between each of the pairs of the bend-resistant strips with the polymer strip partially overlapping both of the bend-resistant strips of the respective pair. A second longitudinally extending nonwoven tape that covers and extends transversely to both sides of the polymer strip is applied over the bend-resistant strips and the polymer strips to form a laminate with the polymer strip between the first and second nonwoven tapes.

Diaper closure and method of making same

A textile web from which elastically stretchable diaper closures can be stamped is made by first passing a pair of nonwoven textile webs longitudinally through a first laminating station at a predetermined first speed and inserting a plurality of longitudinally extending and transversely spaced strips of an elastic polymer between the webs at the first laminating station. This laminates the webs and strips together into an intermediate laminate having longitudinally extending zones where the webs are directly laminated to each other alternating with longitudinally extending stretch zones where the elastic strips are laminated between the webs. This intermediate laminate then passes through a second lamination station downstream of the first lamination station at a predetermined second speed smaller than the first predetermined speed. In the second lamination station respective inelastic strips are adhered to opposite faces of the intermediate laminate in the zones between the stretch zones.

Method of making a textile web from which elastically stretchable diaper closures can be stamped

An elastic composite strip has a longitudinally elongated substrate strip having a pair of opposite faces and formed of an elastomer that is highly stretchable longitudinally but only limitedly or not stretchy at all transversely. A respective soft knit fabric cover strip that is highly stretchable longitudinally but only limitedly or not stretchy at all transversely extends longitudinally on each of the faces. Respective arrays of longitudinally spaced and transversely extending lines of adhesive are bonded to the faces and to filaments of the respective cover strips.

Elastic composite tape

A laminate usable as a diaper closure has a pair of generally contiguous outer fleece layers having longitudinally extending and parallel outer edges and a core layer of foil of LP or LLP polyethylene extending between the outer layers substantially a full width of the outer layers between the edges. The foil has a thickness between 5 &#x3bc;m and 20 &#x3bc;m. Bonds are provided between the core layer and each of the outer layers. The laminate has regions activated by stretching and in which the laminate is semielastric, and unactivated regions in which the laminate is not stretchy.
