Abstract

　La présente invention porte sur une technique par laquelle une augmentation importante de la longueur d'un ruban adhésif peut être réalisée sans faire de changement à un rouleau existant ou au mécanisme pour appliquer un adhésif. Dans la présente invention, une pluralité de rubans adhésifs (2) dans lesquels une couche adhésive (21) et un film de recouvrement antiadhésif (22) sont agencés dans l'ordre sur un film de base (20) sont reliés sur un substrat de liaison (30) par l'intermédiaire d'un ruban de liaison (3) dans lequel une couche adhésive (31) et un film antiadhésif (32) sont agencés dans l'ordre. On adopte une configuration dans laquelle une partie d'extrémité du film de base (20) du ruban adhésif (2) et une partie d'extrémité du substrat de liaison (30) du ruban de liaison (3) sont collées par un élément adhésif (41) du côté substrat, une partie d'extrémité du film de recouvrement antiadhésif (22) du ruban adhésif (2) et une partie d'extrémité du film antiadhésif (32) du ruban de liaison (3) sont collées par un élément adhésif (42) du côté antiadhésif et le film de recouvrement antiadhésif (22) et le film antiadhésif (32) sont intégralement séparés. Une partie de soulèvement (2A) servant à aider la séparation, formée de façon à diminuer en largeur en amont dans la direction de la séparation, est située sur une partie d'extrémité du ruban adhésif (2) sur un côté amont de ce dernier dans la direction de la séparation du film.
