Abstract
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).
Claims13
A hollow spindle for the manufacture of elastic twisted yarns, comprising a thread channel extending coaxially with respect to a spindle axis, through which thread channel is axially moved an elastic core yarn, wherein the thread channel has ribs on its inner surface, which ribs extend in a peripheral direction and project radially inwardly over the surface, so that the yarn running through the thread channel engages radially inward tips of the ribs so as to be supported at a distance from the inner surface.
