Abstract

L'invention concerne un dispositif de raccordement de bande permettant de raccorder l'extrémité coupée d'une pellicule précédente (W1) avançant dans une direction et le bout d'une nouvelle pellicule (W2) entraînée dans la même direction. Des rouleaux de fixation (1, 2) sont disposés au-dessus et en dessous du chemin d'avance de la pellicule précédente, et une lame de coupe (6) est disposée en amont. Le bout de la nouvelle pellicule est collé au rouleau de fixation inférieur (2) par le biais d'un ruban adhésif (T2) et un ruban adhésif (T1) est collé au rouleau de fixation supérieur (1). Dans cette configuration, les deux pellicules (W1, W2) sont raccordées l'une à l'autre de la façon suivante : une pression de contact est générée entre les rouleaux de fixation supérieur et inférieur (1, 2) tandis que la pellicule précédente (W1) est intercalée entre eux ; la pellicule précédente est coupée au moyen de la lame de coupe (6) ; les deux rouleaux (1, 2) sont ensuite mis en rotation dans la direction de distribution des deux pellicules (W1, W2), et l'extrémité coupée de la pellicule précédente est alignée avec le bout de la nouvelle pellicule ; et le ruban adhésif (T1, T2) est collé le long des deux extrémités alignées.
