ABSTRACT:
A twist tube for a false twist device is described which is of the type wherein textile yarn being textured passes through a straight tubular part to a transverse pin of hard material round which the yarn is wound once prior to leaving the tube. To avoid ballooning at very high rotational speeds of the twist tube about its axis, the pin is fixed in the tubular part with its axis displaced laterally with respect to the tube axis by a distance which is a fraction of the pin diameter. Between its cylindrical ends the pin is formed with a cylindrical concave surface providing a gap with respect to the tube axis of a width of the order of half the yarn thickness. To aid threading, openings are provided on opposite sides of the tubular part and the one nearest the laterally displaced pin is enlarged to balance the twist tube about its axis.
