Abstract: A method for the production of a fleece laminate material that has elastic regions and non-elastic regions. In the method, parallel strips of elastic laminate are laminated in between two webs of nonwoven material, at a distance from one another and the nonwoven webs are directly bonded to one another, in the regions between the strips, and form non-elastic regions. The segments of the fleece laminate material that contain a strip, in each instance, form elastic regions. According to the invention, the elastic laminate has a tacky elastomer core layer and at least one non-blocking outer layer of nonwoven material, applied to the tacky core layer.

Abstract: A method is disclosed for the production of an air-permeable laminate film with a textile surface and elastic and non-elastic regions. At least one film strip that is elastic in the crosswise direction is introduced, as an elastic insert, between two material webs of fiber non-woven fabric having a web width greater than the width of the film strip. The segments of the material webs made of fiber non-woven fabric that are in direct contact next to the insert are connected, forming a non-elastic region of the laminate film. Subsequently, the laminate passes through an ultrasound bonding station, in which the elastic insert is melted by means of point-shaped bonds, while maintaining the substance of the fiber non-woven fabric, thereby connecting the elastic insert with the fiber non-woven fabric cover layers at discrete points and forming air-permeable structures.

Abstract: An elastic film laminate includes a first film and at least one second film. The first film is elastomeric in at least one direction and can be reversibly stretched by a length &Dgr;lA during a deformation without demonstrating substantial residual deformation &Dgr;la. The second film is made of a deformable plastic connected with the first film in localized connection regions less than the entire length of the first film. The second film has received a permanent deformation &Dgr;lb significantly greater than the residual deformation &Dgr;la, by means of a common deformation by a length &Dgr;lA, so that the second film is permanently deformed between the localized connection regions. In a renewed deformation of the film laminate above a limit range of deformation, where &Dgr;l>&Dgr;lA applies, the second film exhibits a reaction force that causes the tensile force required for further stretching of the laminate to increase suddenly.

Abstract: A method for the production of an elastic, air-permeable laminate film is disclosed, whereby material webs made of a fiber non-woven fabric are applied to both sides of an elastomer layer, and the multi-layered material subsequently runs through an ultrasound bonding station. The elastomer layer is melted to form point-shaped bonds at discrete locations by means of ultrasound, while maintaining the substance of the fiber non-woven fabric. An air-permeable structure is formed at the melted sites. According to the method, a melt film made of a thermoplastic elastomer is passed to a laminating unit and introduced, in the thermoplasticized state, between two material webs of fiber non-woven fabric that run into the laminating unit. The melted intermediate layer of the multi-layered material is cooled to solidification temperature, whereby a laminate with cover layers made of fiber non-woven fabric is produced. The laminate is subsequently passed to the ultrasound bonding station.
