Definitions

  • a twist stopping device of the aforeoutlined structure It is a disadvantage of a twist stopping device of the aforeoutlined structure that the yarn is braked by the interaction of the two stationary slide faces. It is a serious drawback of this twist stopping device that it may cause breakage of the elementary filaments.
  • a twist stopping device comprising a pinching roll pair, wherein one roll is provided with a flat circumferential groove in which the yarn is spread with the aid of the other roll, so that a propagation of the twist is prevented.
  • Such a twist stopping device is, however, adapted only for yarns formed of a plurality of elementary filaments; it cannot be used for monofils.
  • FIG. 2 is a front elevational view of the device shown in FIG. 1;
  • the false twist member 20 imparts to the yarn upstream and downstream thereof a twist in opposite directions (false twist), which, in the absence of the twist stopping device 17, would propagate up to the first godet 12 against the direction of the yarn feed. This would result in a lateral travel of the yarn on godet l2 and, dependent upon the direction of twist, the yarn would either run off the godet or run into the other yarn windings on the godet.
  • the possibility of such an occurrence is effectively eliminated by the twist stopping device 17 by preventing a propagation of the false twist against the direction of yarn travel.
  • the yarn is trained partially about the yarn guiding pulley 26 so that in the groove 39 it obtained without any clamping of the yarn which would risk the damaging thereof.
  • the yarn dependent upon its tension, is positioned more or less deeply in the yarn guiding groove 39. Since the pulley 26 is supported on the axle 30 with a very low friction and since it has a very small inertia and is not braked, the yarn tension remains practically unaffected by the pulley 26.
  • the yarn guiding groove 39 handles the yarn in the gentlest possible manner and, in the second place, no slippage of the yarn may occur in the yarn guiding groove so that a propagation of the twist of the yarn upstream beyond the pulley is securely prevented under all circumstances.
