Title
(EN) APPARATUS FOR TRANSPORTING AN OPEN TUBE OF MATERIAL
(FR) APPAREIL DE TRANSPORT D'UN MATERIAU SOUS FORME DE TUBE OUVERT
Abstract
(EN)
A transport mechanism (28) for pulling and transporting a rotating open tube (16) in a downline direction, without distorting or closing the tube, and while allowing access to a central longitudinal cavity (60) of the tube from the downline side of the tube, is disclosed. The transport mechanism includes a plurality of drive rollers (30) positioned to engage the tube on only the outside of the tube. The drive rollers pull the tube downline without contacting the inside of the tube. The drive rollers are uniformly distributed around the tube and are mounted on preferably all of the sides of a regular polygon. The transport mechanism also includes a motor (78) which rotates the drive rollers around their respective axes and a motor (74) which spins the drive rollers around a central axis substantially colinear with the central axis of the open tube to rotate the open tube.
(FR)
Mécanisme transporteur (28) servant à transporter un tube ouvert tournant (16), dans le sens voulu sans déformer ni fermer le tube, et tout en permettant l'accès, à partir de l'avant du tube à une cavité centrale longitudinale (60) de ce dernier. Ledit mécanisme comprend une pluralité de rouleaux d'entraînement (30) disposés pour n'entrer en prise qu'avec l'extérieur du tube et pour faire avancer le tube sans entrer en contact avec l'intérieur de celui-ci. Lesdits rouleaux sont répartis de manière uniforme autour du tube et de préférence montés sur toutes les faces d'un polygone régulier. Le mécanisme transporteur comprend également un moteur (78) destiné à faire tourner lesdits rouleaux autour de leurs axes respectifs, et un moteur (74) destiné à entraîner en rotation les rouleaux autour d'un axe central situé sensiblement sur la même droite que l'axe central du tube ouvert, de manière à faire tourner ce dernier.
