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).
L'invention concerne un procédé simple pour fabriquer un produit présentant au moins deux couches de matériau flexibles (14, 15), reliées l'une à l'autre au moyen d'une couche de colle appliquée sur des faces intérieures tournées l'une vers l'autre des couches de matériau (14, 15), ces couches de matériau (14, 15) étant pressées l'une contre l'autre puis perforées en discontinu. Selon ledit procédé, la colle est introduite par pression dans les trous de perforation formés au même moment à partir d'au moins une face extérieure des couches de matériau (14, 15) et la colle (16) est amenée dans l'espace intermédiaire entre les couches de matériau (14, 15).
