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.
