Abstract

L'invention concerne un dispositif (2) de transfert de bande transporteuse destiné à être inséré puis retiré d'une section de courroie d'une bande sans fin (2) montée sur un transporteur (1). Le dispositif (12) comprend au moins un bras (20) de déflecteur monté par pivotement sur une structure (13) et servant de support à un rouleau (21) d'entraînement. Le bras (20) du déflecteur se déplace pour permettre au rouleau (21) d'entraînement de venir en contact avec la bande sans fin (2) et d'éloigner la bande sans fin (2) du transporteur (1), maintenant celle-ci dans une configuration d'entraînement. Un dispositif (22) de fixation de la bande monté sur ladite structure (13) vient en contact avec une section de la bande sans fin (2) dans la configuration d'entraînement. Des moyens (23) d'entraînement montés sur ladite structure (13) viennent en contact de manière amovible avec les faces opposées de la bande sans fin (2) lorsque celles-ci est maintenue dans la configuration d'entraînement. Les moyens (23) d'entraînement tirent la bande sans fin (2) et maintiennent celle-ci (2) sous tension afin de permettre à une section de la bande sans fin (2) entre ledit dispositif (22) de fixation de la bande et lesdits moyens (23) d'entraînement de se relâcher.
