A method and an apparatus (2) for mounting self-adhesive foil (19) which is provided with a liner (21) treated with anti-seize, where a transverse cut is performed in the liner (21) at a short distance from a free end edge (37) of the foil (19), where the self- adhesive foil (19) is rolled up to form a roll with the front side of the foil (19) facing outwards in the roll, and with the upper part of the image on the foil disposed at the free edge (37) of the roll, where the free edge (37) of the foil (19) is fixed externally on an application apparatus (2), where the foil roll is placed in the application apparatus (2) with the free end of the roll passed out of the apparatus through an outlet aperture or slot before closing and fixing a Kd (12) over an inlet aperture (18), where the liner (21) is released from the foil (19) below the transverse cut, and where the upper part of the foil is disposed in the desired position of application, as a plane top side (27) of the application apparatus (2) is preferably used as aiming means, whereafter the foil is transferred under pressure against the surface of application and simultaneous downward movement of the application apparatus (2), the foil being mounted in stretched position on the application surface, as the liner (21) is continuously released from the foil (19) at the same time.

L'invention concerne un procédé et un appareil (2) pour le montage d'une pellicule auto-adhésive (19) pourvue d~une doublure (21) traitée avec un antigrippant, selon lesquels une découpe transversale est pratiquée dans la doublure (21) à une courte distance d~un bord d~extrémité libre (37) de la pellicule (19) ; la pellicule auto-adhésive (19) est enroulée pour constituer un rouleau avec le recto de la pellicule (19) faisant face à l~extérieur dans le rouleau, et avec la partie supérieure de l~image sur la pellicule disposée au niveau du bord libre (37) du rouleau ; le bord libre (37) de la pellicule (19) est fixé à l~extérieur sur un appareil d~application (2) ; le rouleau de pellicule est placé dans l~appareil d~application (2) avec l~extrémité libre du rouleau sortant de l~appareil à travers une ouverture de sortie ou une fente avant de fermer et de fixer un couvercle (12) au-dessus d~une ouverture d~entrée (18) ; la doublure (21) est détachée de la pellicule (19) sous la découpe transversale ; et la partie supérieure de la pellicule se trouve dans la position d~application désirée, dans la mesure où un côté supérieur plan (27) de l~appareil d~application (2) est de préférence utilisé comme moyen de visée, après quoi le rouleau est transféré sous pression contre la surface d~application avec le mouvement vers le bas simultané de l~appareil d~application (2), la pellicule étant montée en position tendue sur la surface d~application, pendant que la doublure (21) est détachée de manière continue de la pellicule (19).
