Definitions

  • the yarn guide of DE 35 06 552 A1 act as deflection that take the thread from each other or from the transport roller, deflect it and send it back to the transport roller or on the other thread guide. Since the thread windings continue to run around the transport roller around, albeit in a partially extended by the thread guide bow, the deflection angles occurring at the thread guides are large. This has the consequence that counteract the thread guide caused by the frictional forces arising in the deflections of the transferred from the transport roller surface on the thread feed force, which has a negative effect not only on the effectiveness of the yarn transport itself but also on the Maintaining a uniform thread tension by the feeder. Thread tension irregularities, in turn, can cause inaccuracies or errors in knitting processing which, in turn, result in defects in the fabric being processed. Furthermore, the setting of the yarn transport in DE 35 06 552 A1 due to the many adjustable yarn guide whose relative positioning is critical to each other, complicated for the operator.
  • the total wrap angle on both transport rollers is 315 ° in this example. With two wraps and the two possible positions of the deflecting elements indicated in the figure, this is the minimum wrap angle.

Abstract

L'invention concerne une bobine débitrice de fil à friction destinée à recevoir un ou une pluralité de fils d'au moins un dispositif d'alimentation en fil correspondants et à amener au moins un des fils à un point de traitement de fil d'une machine à tricoter. Au moins deux rouleaux disposés parallèlement entre eux reçoivent les fils et les transportent en enlevant les fils des rouleaux par friction sur les surfaces des rouleaux. Un élément de déviation sert à ajuster la force d'entraînement exercée par les rouleaux sur au moins un des fils ; les rouleaux sont disposés de telle sorte que les fils puissent être enroulés autour des deux au moins une fois. L'élément de déviation peut être réglé de manière à dévier le fil ou les fils dans une partie du profil d'enroulement de fil entre les rouleaux de sorte que l'angle d'enroulement du fil ou des fils autour des rouleaux, et avec lui la longueur de contact du fil ou des fils avec les surfaces des rouleaux peut éventuellement être augmenté ou diminué.
