Title
(EN) APPARATUS AND METHOD FOR CONTROLLING THE TENSION ON A YARN BUNDLE WITHDRAWN FROM A MASS OF COMPACTED YARN
(FR) APPAREIL ET PROCEDE DE COMMANDE DE LA TENSION D'UN FAISCEAU DE FILS TIRES D'UNE MASSE DE FIL COMPACTE
Abstract
(EN)
An apparatus (1) for controlling the tension on yarn withdrawn from a mass of compacted yarn within a confined space has a yarn guide element (2) with a tubular wall portion defining the confined space for guiding and for accumulating a compacted mass of yam (5), an inlet opening (3) for entry of the compacted yarn mass into one end of the confined space and an outlet opening (8) for allowing withdrawal of the yam as a yarn bundle (9) from the confined space. The outlet opening (8) is an elongated slot that is provided in the wall portion of the guide element. The slot has a preselected configuration so that the slot will vary the tension applied to the yam bundle as the yarn mass moves from one end of the confined space to the other end.
(FR)
Appareil (1) de commande de la tension d'un fil tire d, une masse de fil compactee dans un espace clos, lequel appareil possede un element de guidage du fil (2) avec une portion de paroi tubulaire definissant l'espace clos pour guider et pour accumuler une masse compactee de fil (5), une ouverture d'entree (3) pour l'entree de la masse de fil compactee dans une extremite de l'espace clos et une ouverture de sortie (8) pour permettre l'extraction du fil sous la forme d'un faisceau de fils (9) de l'espace clos. L'ouverture de sortie (8) est une fente allongee qui est amenagee dans la portion de paroi de l'element de guidage. La fente possede une configuration predeterminee de telle sorte qu'elle modifie la tension appliquee sur le faisceau de fils au fur et a mesure que la masse de fil se deplace d'une extremite de l'espace clos vers l'autre extremite.
