A method and device for applying a pattern (70) onto a support means (2) of a sign, utilising a foil (17) comprising a pattern layer (18) and a carrier layer (73) with an adhesive layer (74) uniting them, said pattern being cut out in the pattern layer of the foil by means of a controlled cutting device, after which the foil is placed on a laminating table (3) in an application device (1). According to the invention a traverse (21) is passed in controlled manner over the foil placed on the laminating table, and a self-adhesive transfer film (19), supplied from a roll (20) over and around a press roll (34) rotatably journalled, at a press device (32) is applied under pressure on the foil. The carrier layer and spill of the pattern layer are removed and the pattern parts thus remaining are brought into contact with the support means, with the adhesive layer of the pattern parts now exposed. The press roll is then again passed over the transfer film, pattern parts and support means so that the pattern parts are transferred permanently to said support means, after which the transfer film is removed from the support means.

L'invention concerne un procédé et un dispositif permettant d'appliquer un motif (70) sur un support (2) d'un panneau, à l'aide d'une feuille (17) comprenant une couche motif (18) et une couche support (73) assemblées par une couche adhésive (74). Le motif est découpé dans la couche motif de la feuille au moyen d'un dispositif de coupe commandé. Ensuite, la feuille est placée sur une table de stratification (3) dans un dispositif d'application (1). Selon l'invention, une traverse (21) est passée de façon commandée sur la feuille posée sur la table de stratification et un film de transfert autoadhésif (19) délivré par un rouleau (20) passe sur et entoure un rouleau presseur (34) monté pivotant sur un dispositif de presse (32), puis est appliqué par pression sur la feuille. La couche support et les chutes de la couche motif sont enlevées et les parties motif restantes sont mises en contact avec le support, la couche adhésive de ces parties motif étant à présent à nu. Le rouleau presseur est passé une nouvelle fois sur le film de transfert, les parties motif et le support de telle façon que les parties motif soient transférées de façon permanente sur le support. Le film de transfert est ensuite retiré du support.
