Title (EN) TUBE ELEMENT FOR TUBULAR CONVEYOR
(FR) ELEMENT TUBULAIRE POUR AGENCEMENT TUBULAIRE DE TRANSPORT
Abstract:
(EN) A tubular conveyor is known with which textile card slivers are conveyed by means of an air current. Experience has shown that the conveying of these card slivers, in particular at bends in the tube of approximately 90°, is not smooth and that breaks in the slivers or blockages may result. To prevent blockages and breaks in the slivers, a tube element for the conveyor has at least one section (3) through which a rotary disk (9) projects into the tube element (10). This disk ensures that the card sliver lies on the outer surface of the disk. The disk moves in function of the speed of the cards liver in such a way that no sliding friction is exerted on the card sliver. The tube element can be used for tubular conveyors for conveying textile card slivers.
(FR) On connaît des agencements tubulaires de transport de rubans de cardes textiles entraînés par un courant d'air. Il s'est révélé que le transport de tels rubans de cardes, notamment aux coudes des tuyaux d'environ 90°, ne se fait pas sans friction, ce qui peut provoquer des ruptures des rubans ou des obstructions. Afin d'éviter des ruptures du ruban ou des obtstructions, un élement tubulaire de l'agencement de transport comprend au moins une section (3) traversée par un disque rotatif (9) qui fait saillie à l'intérieur de l'élément tubulaire (1). Ce disque porte sur sa surface extérieure le ruban de carde et se déplace en fonction de la vitesse du ruban de carde, de sorte qu'aucune friction de glissement ne s'exerce sur le ruban de carde. Cet élément tubulaire peut être mis en oeuvre dans des agencements tubulaires de transport de rubans de cardes textiles.
