Abstract

L'invention concerne un dispositif et un procédé correspondant de fabrication de tricot au moyen d'une machine à tricoter et d'une unité d'étirage et de consolidation de mèches qui présente une unité de stockage de mèches contenant au moins une mèche, un banc d'étirage raccordé à l'unité de stockage de mèches, une filière placée en aval du banc d'étirage dans une direction de transport de mèches du dispositif et formant une unité de consolidation des fibres par exposition à de l'air comprimé, et une paire de rouleaux de serrage de fils d'extrémité pouvant tourner en sens opposés, agencée en aval de la filière dans le sens de transport des mèches et délimitant l'unité de consolidation des fibres. Le dispositif présente au moins un dispositif de soufflage de la filière et/ou du banc d'étirage et au moins un dispositif de de retrait par aspiration servant à retirer des fils détachés de la filière et/ou du banc d'étirage. Selon la présente invention, le dispositif de retrait par aspiration et le dispositif de soufflage sont reliés en un système de soufflage et de retrait par aspiration. Le dispositif de retrait par aspiration présente un dispositif de purification de l'air d'aspiration muni d'au moins un dispositif de ventilation, et au moins une sortie d'air évacué du dispositif de purification de l'air d'aspiration est reliée à au moins un conduit d'air s'étendant au-dessus de la ou des paires de rouleaux de serrage de fils d'extrémité et présentant au moins une ouverture de conduit qui est orientée sur ou le long de la filière et/ou sur ou le long du banc d'étirage.
