ABSTRACT:
A bundle of textile fibres 1, e.g. a sliver or roving supplied by a drafting apparatus 2, is passed over a frictional surface 7 provided by a rotary disc 6 so that the surface 7 moves transversely to the path of movement of the bundle 1. The resultant twist is prevented from running back into the drafting apparatus 2 by exit rollers 5, and from running forward to take-up bobbin 16 by draw-off rollers 13, 14. The resultant product is a fancy thread containing a false twist but on which the sum total of the residual twist is substantially zero. Thread 17 is used for threading-up the apparatus, but such a thread may also be fed to the disc 6 to form a composite with the bundle 1. Modifications provide for two or more bundles to be supplied simultaneously to the same disc 6 with one or all contacting the roughened surface 7 and for one or more bundles to be treated in successive discs 6 and combined at one of the successive discs 6.
