Abstract

La présente invention concerne un banc d'étirage (10) destiné à une machine à tricoter pour la fabrication d'un bandage de fibres à partir d'une mèche. Ledit banc d'étirage comporte des lanières doubles guidées par une paire de rouleaux de lanière (14, 15) et une paire de rouleaux presseurs de sortie (16, 17). La paire de rouleaux de lanière (14, 15) et la paire de rouleaux presseurs de sortie (16, 17) comportent chacune un rouleau presseur supérieur (15, 17) et un rouleau inférieur (14, 16) entraîné par un moteur électrique. Les rouleaux (12 - 17) sont disposés du côté avant (11.1) d'une plaque de base (11) tandis que leurs axes (26, 27, 28) passent à travers la plaque de base (11). Les moyens d'entraînement des rouleaux inférieurs (12, 14, 16) sont disposés au moins partiellement du côté arrière de la plaque de base (11). Un dispositif d'aspiration (20) s'étendant au-dessus des deux rouleaux supérieurs (15, 17) est disposé au niveau du rouleau supérieur (17) de la paire de rouleaux presseurs de sortie (16, 17) et du rouleau supérieur (15) de la paire de rouleau de lanière (14, 15).
