Une feuille de film de résine équipée d'une couche adhésive comprend un film de résine et utilise un corps multicouche de film de résine composé d'un long film de support en forme de bande et d'un film de résine qui a une dimension prescrite dans une direction de largeur et est empilé sur le film de support avec une couche adhésive interposée entre eux, et la feuille de film de résine équipée d'une couche adhésive est découpée de manière à avoir une dimension prescrite dans une direction de longueur conjointement avec la couche adhésive sur le film de support. Dans une station d'adhérence, la feuille de film de résine équipée d'une couche adhésive est décollée du film de support et collée à un panneau de forme fixe ayant une forme prescrite. Le système d'adhérence comprend : un dispositif de transport de panneau de forme fixe qui est destiné à transporter un panneau de forme fixe à travers une station d'adhérence ; et un mécanisme de rouleau d'adhérence qui est destiné à faire adhérer la feuille de film de résine équipée d'une couche adhésive qui a été décollée du film de support au panneau de forme fixe qui a été transporté jusqu'à la station d'adhérence, et qui est disposé dans la station d'adhérence. Le dispositif de transport de panneau de forme fixe comprend : un élément de maintien d'aspiration pour une aspiration maintenant le panneau de forme fixe ; un mécanisme d'entraînement d'élément de maintien d'aspiration pour entraîner l'élément de maintien d'aspiration de telle sorte que l'élément de maintien d'aspiration se déplace d'un mouvement de va-et-vient le long de trajets aller et retour, comprenant un trajet aller qui passe à travers la station d'adhérence et qui se trouve entre une extrémité de départ sur le côté de trajet aller et une extrémité arrière de pliage, et un trajet retour qui s'étend de l'extrémité arrière de pliage vers au moins ladite extrémité de départ par l'intermédiaire de la station d'adhérence ; et un mécanisme d'aspiration qui permet à l'élément de maintien d'aspiration entraîné par le mécanisme d'entraînement d'élément de maintien d'aspiration d'appliquer une force d'aspiration.
