Abstract (en)
[origin: US6293079B1] A hollow spindle, in particular for the manufacture of elastic twisted yarns, has a thread channel (9) extending coaxially with respect to the axis of the spindle (A), through which thread channel is axially moved a yarn (6), in particular an elastic core yarn. The thread channel (9) has ribs (10) on its inner surface (8a), which extend in peripheral direction or helically and project inwardly over the surface (8a), so that the yarn (6) running through the thread channel (9) rests only pointlike on the ribs, otherwise, however, is supported at a distance from the inner surface (8a).
