Abstract
A laminate material element (1) for a hook and loop closure, particularly a diaper closure, has a carrier film (2) and a textile material (3) laminated onto the carrier film (2), which has a surface structure that is suitable for forming a connection with the hooks of a hook and loop closure. The carrier film (2) and the textile material (3) are bonded together over their entire surface in an edge region that extends along the edges of the laminate material element and has the shape of a frame. A bond between the carrier film (2) and the textile material (3) that does not cover the entire surface is provided in the region within this frame.

Method for producing a laminate material element for a hook and loop closure comprising the following steps:
- supplying an adhesive surface to an imprinted carrier film in a register, applying the adhesive over the entire area in a frame-shaped edge region forming a pattern of an adhesive frame and contact regions surrounded by the adhesive frame, said adhesive in the region surrounded by the adhesive frame being arranged in an adhesive pattern whereby the contact regions are composed of adhesive-covered areas and regions that are free of adhesive;
- applying a material web of a textile material, which has a surface structure suitable for forming a connection with hook and loop hooks, to the side of the carrier film to which adhesive has been applied, wherein the textile material comprises a warp-knitted material, which has a basic interlaid scrim or filament yarns and loops connected with the basic interlaid scrim using knitting technology and pressing the textile material together with the carrier film to form a laminate material, wherein the carrier film and the textile material are glued to one another;
- cutting off laminate material elements, which are connected via the adhesive areas applied as adhesive frames, over the entire area, along the edges, from the laminate material.
