Title
(DE) FADENLIEFERGERÄT MIT NEUARTIGEM FADENFÜHLER
(EN) THREAD DELIVERY DEVICE HAVING A NOVEL YARN SENSOR
(FR) DISPOSITIF DÉLIVREUR DE FIL À PALPEUR DE FIL NOVATEUR
Abstract
(DE)
Bei einem hinsichtlich seines Fadenfühlers verbesserten Fadenliefergerät (1) bilden der Fadenfühler (18) und eine zugeordnete Fadenführungseinrichtung (12) vorzugsweise eine Baueinheit, die parallel zu der Drehachse des Fadenlieferrads (3) verstellbar ist. Zu dem Fadenfühler (18) gehört ein Hebel (19) oder ein anderweitiges Element, das vorzugsweise aufrecht stehend angeordnet ist. Es erstreckt sich somit in einer ersten Querrichtung von dem Faden weg. In einer ersten Ausführungsform ist es in einer zweiten Querrichtung (Schwenkrichtung) beweglich während es in einer zweiten Ausführungsform längs verschiebbar gelagert ist. Durch die ausschließlich quer, vorzugsweise rechtwinklig zu dem Faden orientierte Bewegung des Fadenfühlers werden durch den laufenden Faden verursachte, auf den Fadenfühler wirkende Bewegungsimpulse minimiert. Durch die vertikale Anordnung des Fadenfühlers wird es außerdem möglich, den Fadenfühler für einen sehr weiten Bereich verschiedener Garnstärken vom dünnsten Polyesterfaden bis zu dickem Effektgarn zu verarbeiten.
(EN)
In a thread delivery device (1) which is improved with regard to its thread sensor, the thread sensor (18) and an associated thread guiding device (12) preferably form one structural unit which can be adjusted parallel to the rotational axis of the thread delivery wheel (3). A lever (19) or another element which is preferably arranged so as to stand upright belongs to the thread sensor (18). It therefore extends in a first transverse direction away from the thread. In a first embodiment, it is movable in a second transverse direction (pivoting direction), while it is mounted such that it can be displaced longitudinally in a second embodiment. Movement pulses which are caused by the running thread and act on the thread sensor are minimized by the movement of the thread sensor, which movement is oriented exclusively transversely, preferably at right angles, with respect to the thread. Moreover, the vertical arrangement of the thread sensor makes it possible to use the thread sensor for a very wide range of different thread thicknesses from the thinnest polyester thread to a thick fancy yarn.
(FR)
L'invention concerne un dispositif délivreur de fil (1) à palpeur de fil amélioré. Le palpeur de fil (18) et un guide-fil associé (12) y constituent de préférence un ensemble qui peut être déplacé parallèlement à l'axe de rotation de la roue délivreuse de fil (3). Le palpeur de fil (18) comprend un levier (19) ou autre élément qui est de préférence disposé en position verticale. Cet élément s'étend ainsi en éloignement du fil dans une première direction transversale. Dans une première forme de réalisation, cet élément est mobile dans une seconde direction transversale (direction de pivotement), tandis que dans une seconde forme de réalisation, il est monté à translation longitudinale. Comme le mouvement du palpeur de fil est orienté exclusivement transversalement et de préférence perpendiculairement au fil, les impulsions de déplacement agissant sur le palpeur sont minimisées. La disposition verticale du palpeur de fil permet en outre d'utiliser le palpeur pour une très large plage d'épaisseurs de fil, allant du fil polyester le plus mince aux épais fils fantaisie.
