Abstract

La présente invention concerne : un dispositif de pliage de pièce de tissu qui peut empêcher la dégradation de bandes transporteuses causée par le contact avec une plaque de pliage ; et un procédé de commande dudit dispositif de pliage de pièce de tissu. La présente invention est pourvue de bandes transporteuses (12, 13) qui transportent une pièce de tissu, et d'un dispositif de pliage (32) qui est pourvu d'une plaque de pliage (32a). Le dispositif de pliage (32) peut être temporairement immobilisé au niveau d'une position d'attente (III) entre une position en poussée (I), dans laquelle la plaque de pliage (32a) est la plus proche des bandes transporteuses (12, 13) et une position rétractée (II), dans laquelle la plaque de pliage (32a) est la plus éloignée des bandes transporteuses (12, 13). Comme la plaque de pliage (32a) peut être mise en attente au niveau de la position d'attente (III) qui est écartée des bandes transporteuses (12, 13) après avoir poussé la pièce de tissu vers l'intérieur, il n'existe pas de contact direct entre la plaque de pliage (32a) et les bandes transporteuses et la dégradation des bandes transporteuses, causée par le contact avec la plaque de pliage (32a), peut être empêchée.
