A process for manufacturing individual layered structures (12) and the individual layered structures (12) produced. There is provided a continuous web layered structure (14) having cutting lines across the width. The continuous web layered structure (14) contains particulate materials (6, 7, 9) between two containing layers (1, 2). One of the two containing layers (1, 2) is permeable to liquids. A thermoplastic material (16), in liquid form, is applied to the continuous web layered structure (14) over at least part of the cutting lines. The thermopalstic material (16) will join the two containing layers (1, 2) at each point of application. The thermoplastic material (16) is allowed to set. The continuous web layered structure (14) is cut along the cutting lines within the applied thermoplastic material (16) to provide individual layered structures (12).
L'invention porte sur un procédé de fabrication de structures (12) individuelles en couches comportant les étapes suivantes: (a) fournir une structure en couches (14) en bande continue, comportant des lignes de découpe sur sa largeur et comprenant des matériaux particulaires (6, 7, 9) entre des couches de contention (1, 2), l'une au moins des couches (1, 2) étant perméable aux liquides; (b) appliquer un matériau thermoplastique (16) sous forme liquide, sur la structure en couches (14) en bande continue sur au moins une partie des lignes de découpe de manière à ce que le matériau thermoplastique (16) une fois appliqué lie les couches de contention (1, 2); (c) laisser durcir le matériau thermoplastique (16); (d) découper la structure en couches (14) en bande continue suivant les lignes de découpe de manière à obtenir les structures individuelles (14) en couches. L'invention porte également sur une structure individuelle en couches (12) ainsi obtenue.
