Abstract

L'invention concerne un procédé de fonctionnement d'une tête de bobinage d'une machine de texturation ainsi qu'une telle machine de texturation pourvue d'une pluralité de têtes de bobinage (2). La machine de texturation présente plusieurs unités de traitement (7.1, 7.2, 13) pour l'étirage et la texturation d'un fil (3) qui est ensuite enroulé dans la tête de bobinage (2) associée pour former une bobine (18). Des bobines (18) enroulées pleines sont retirées par un opérateur et remplacées par une bobine vide (32). Pour accorder à l'opérateur un plus grand espace de manoeuvre lors de la commande des têtes de bobines, l'invention prévoit que le fil entrant (3) est automatiquement coupé en l'absence d'un changement manuel de la bobine et est transporté en continu par un flux d'aspiration et cédé à un contenant de déchet de filé (24). A cet effet, la tête de bobine (2) est associée à un dispositif de prise de fil (21) qui, en l'absence d'un changement manuel de la bobine, provoque une séparation et un transport du fil entrant.
