Abstract

L'invention concerne un dispositif (1) et un procédé de transport de corps de sacs (2) tubulaires, comprenant un système de transport longitudinal (3) avec lequel les corps de sacs (2) tubulaires peuvent être transportés sensiblement dans la direction (3') de leur projection longitudinale, comprenant un système de transport transversal (8) avec lequel les corps de sac (2) tubulaires peuvent être transportés sensiblement perpendiculairement à leur projection longitudinale, et comprenant un système de transfert (9) servant à transférer les corps de sac (2) tubulaires du système de transport longitudinal (3) au système de transport transversal (8). Le système de transfert (9) possède au moins une surface d'appui supérieure (10) et une surface d'appui inférieure (11) pour les corps de sac (2) tubulaires et il est prévu un élément d'aiguillage (12) qui peut être basculé entre une position haute et une position basse. Lorsque l'élément d'aiguillage (12) se trouve en position haute, les corps de sac (2) tubulaires peuvent être acheminés vers la surface d'appui supérieure (10), et lorsque l'élément d'aiguillage (12) se trouve en position basse, ils peuvent être acheminés vers la surface d'appui inférieure (11).
