Means for supporting a false-twist spindle, comprises at least one rigid roller having a flexible tyre and a permanent horse-shoe magnet having its poles spaced apart axially of the roller(s), one on each side thereof, to hold the spindle at or near its ends so that it contacts the tyres intermediate its ends. One roller 12 is on a driven spindle 23; two other rollers are arranged one above and one below the roller 12 on an idle spindle 26 parallel to the spindle 23. Each roller has a polyurethane tyre in a circumferential recess, the roller 12 being in two parts clamped together to secure the tyre 17 in a recess of the shape shown. The spindle is of ferromagnetic material with a twist-pin 11a in an enlarged head, and lies in a cusp formed by rollers, which are disposed so that, received axially, the tyres overlap. The magnet 27 is arranged with its poles above and below the rollers, the poles having concave ends adjacent collars 11b on the spindle.</p> |
