Abstract

L'invention vise à concevoir un dispositif de fixation d'étiquette pouvant fixer de façon parfaite une étiquette longue. L'invention concerne un dispositif de fixation d'étiquette (1) dans lequel une unité de support par aspiration (33) comprend : une unité de corps principal (52) reliée à une source de génération de pression négative ; une surface d'aspiration (55) destinée à être en contact avec une étiquette (L) ; et un trou d'aspiration (56) reliant l'unité de corps principal (52) et la surface d'aspiration (55). La surface d'aspiration (55) est pourvue d'une section évidée (57), qui est en communication avec le trou d'aspiration (56), et présente une forme différente de celle du trou d'aspiration (56) dans une vue en plan. Une unité de commande (10) commande un mécanisme de déplacement (34) de manière à ce que l'unité de support par aspiration (33) applique une force d'aspiration à l'étiquette (L) au moins au niveau de deux positions d'aspiration en fonction de la longueur de l'étiquette (L) produite par une unité de production d'étiquettes (8), lesdites deux positions d'aspiration étant une première position d'aspiration (P1) au niveau de laquelle la section évidée (57) se trouve dans un premier état par rapport à l'étiquette (L), et une seconde position d'aspiration (P2) au niveau de laquelle la section évidée (57) se trouve dans un second état, différent du premier état, par rapport à l'étiquette (L).
