Abstract: A spinning-twisting machine with a hollow spindle, particularly for the production of fancy yarns, includes a drawing frame for an assembly of fibers. A drawing roller is contained in the drawing frame and it is notched at spaced locations around its circumferential surface for suppressing, locally and temporarily, the nip between a pair of drawing rollers. An assembly of fibers is passed between the drawing rollers and then through a hollow spindle where a covering yarn is wrapped around the assembly of fibers. Take-up cylinders draw the combined fancy yarn through the spindle at a peripheral speed greater than the speed of feed rollers supplying the assembly of fibers to the drawing rollers.

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.
