<p>In the take-down mechanism the plurality of coaxial roller sections (14.1 . . . 14.x) of the take-down roller are moveable on a common shaft (16) and adapted to be coupled separately and selectively with a driving means (17/18) that is to say independently of one another. A return rotary movement of the roller sections is prevented by one-way clutches constituted by loop springs (35,36). The common shaft (16) can be turned for adjustment of all the roller sections in common. Annular guards (28) prevent threads intruding between the individual roller sections (14). (FIG. 1).</p> |
