False twist device for an open-end spinning device

摘要

A false twist device for an open-end spinning device to introduce a false twist in a yarn has a largely tubular carcass and several false twist edges arranged behind one another in the yarn draw-off direction and inclined by an angle in the carcass with regard to the yarn draw-off direction. The false twist edges protrude in such a way into the interior of the tubular carcass that the yarn experiences a deflection on each one of the false twist edges. The several false twist edges are arranged offset in such a way in the carcass in circumferential direction that the yarn simultaneously experiences a spatial deflection compared to its regular yarn draw-off direction through the successive deflections on the several false twist edges.

主权项

1. A false twist device for an open-end spinning device to introduce a false twist in a yarn produced in the open-end spinning device, the false twist device comprising:
a tubular carcass; a plurality of false twist edges arranged behind one another in a yarn draw-off direction through the device, each of the false twist edges inclined at an angle (α) in the carcass relative to the yarn draw-off direction; the plurality of false twist edges configured in an interior of the carcass such that each individual false twist edge imparts a deflection to a yarn drawn through the carcass; and the plurality of false twist edges offset in a circumferential direction in the carcass such that the yarn drawn through the carcass is also simultaneously subjected to a spatial, helical, deflection through the successive deflections on the false twist edges.
