  • this variant can have the special feature that the end edge of the discharge plate directed toward the pinch has a form adapted to the form of the lower roller and is situated a small distance from this roller. It is noted that on the discharge side this aspect may generally be slightly less critical, particularly when pressure-sensitive adhesive layers are used, since a thicker structure consisting of mutually adhered layers is inherently stiffer than the individual layers.

Abstract

La présente invention concerne un dispositif permettant à deux couches au moins d'adhérer mutuellement l'une à l'autre, par exemple un support pelliculaire, une feuille porteuse d'information visuelle et une pellicule de couverture, par pression et éventuellement par procédé thermique, avec couche adhésive intercalée. Ce dispositif comprend deux cylindres passifs pressés l'un contre l'autre et définissant ensemble une striction pratiquement horizontale, ainsi qu'une table plane d'alimentation qui sert d'appui aux couches placées d'avance en alignement réciproque afin qu'elles puissent être introduites collectivement et d'une manière relativement plane dans la striction, par déplacement sur la table d'alimentation. Le dispositif selon l'invention est caractérisé en ce que la plaque d'alimentation est disposée avec un tel angle d'inclinaison par rapport à la position horizontale que la pince est située à l'extrémité inférieure de la face supérieure de ladite plaque d'alimentation, et que le plan plat passant par l'axe de rotation des rouleaux s'étend pratiquement à la perpendiculaire par rapport à la face supérieure de la plaque d'alimentation.
