Abstract

L'invention concerne un procédé de collage d'un objet (12) avec un ruban adhésif (16) possédant de préférence un film de protection (26). L'objet est mis au contact du ruban adhésif et, pendant le transport de l'objet, le ruban adhésif qui se déplace également est appliqué sur l'objet. Les vitesses de l'objet et du ruban adhésif sont synchronisées pendant le collage. Afin de permettre un collage de l'objet sans exercer sur le ruban adhésif une influence pouvant affecter l'effet de collage, il est proposé que l'objet soit transporté par un équipement de manutention et que les allures non seulement de la vitesse mais encore de l'accélération de l'objet soient transmises de manière synchrone au transport du ruban adhésif à l'aide d'un axe de l'appareil de manutention.
