The invention relates to a method for producing a strip-shaped object (48) of any thickness, width and length, made up of stacked, partially glued together foil strips (30). According to said method, each of the foil strips (30) is provided with adhesive strips (18) applied across the width (u) of the foil strip on one side, and the adhesive strips (18) are offset from each other on foil strips (30) that directly follow each other. The foil strips (30) are stacked to produce a foil strip stack (39), pressed against each other in the stacking direction and glued together in order to produce the strip-shaped object (48). In the process, a line of foil (22) which is provided with adhesive strips (18) crosswise to its longitudinal direction (x) is divided into at least two lines of foil strips (29) of equal width in its longitudinal direction (u). The individual lines (29) of foil strips are deviated and guided one above the other with adhesive strips (18) which are offset from each other, cut into sections from foil strip packets (34) consisting of individual foil strips (30), in cycles, and fed to the foil strip stack (39) in the form of foil strip packets (34).

L'invention concerne un procédé pour fabriquer un objet (48) en forme de bande, constitué de bandes de feuilles (30) empilées et partiellement collées entre elles, cet objet ayant une épaisseur, une largeur et une longueur quelconques. Chaque bande de feuille (30) est dotée, sur une face, de bandes adhésives (18) placées en la largeur (u) de la feuille, ces bandes adhésives (18) étant posées de manière décalée sur les bandes de feuilles (30) qui se suivent directement. Ces bandes de feuilles (30) sont empilées pour former une pile(39), puis elles sont pressées les unes contre les autres dans le sens de la pile, et collées ensemble pour constituer un objet (48) en forme de bande. Un pan (22) de feuille, comportant une bande adhésive (18) disposée transversalement par rapport au sens de sa longueur (x), est divisé longitudinalement en au moins deux lés (29) de feuilles de même largeur (u). Ces lés (29) sont déviés et guidés l'un au-dessus de l'autre, leurs bandes adhésives (18) étant mutuellement décalées. Puis, ils sont coupés selon une cadence donnée en paquets (34) de bandes de feuilles (30), ces paquets (34) étant ensuite dirigés vers la pile (39) de feuilles.
