The production of a product comprising at least two flexible materials layers (14, 15) which are connected together by means of an adhesive layer applied to mutually facing inner faces of the material layers (14, 15), wherein the material layers (14, 15) are pressed against one another and are then perforated discontinuously, proceeds in a simple manner in that, at the same time as the perforating operation, adhesive (16) is pressed from at least one outer side of the material layers (14, 15) into the perforation holes formed, and thereby the adhesive (16) is passed into the space between the material layers (14, 15). |
