Abstract

To permit, selectively, use of multistrand monofilamentary thread or yarn, or twisted fiber thread or yarn with the same thread supply drum, the pull-off direction is changeably arranged by supporting a take-off thread guide eye (11, 11a) with respect to the axis of rotation (1') of the drum such that the orientation of the eye is either radial (FIG. 2: I; FIG. 3) or essentially tangential (FIG. 2: II, III; FIG. 4) or intermediate thereof; in the radial direction, individual strands which might be torn or broken are carried along by the running thread; in the tangential direction (FIG. 4), loose ends of fibers of fibrous yarn will not entangle other loops on the storage winding (22) of the drum. The take-off guide eye (11, 11a) either is secured to a pivotable U-shaped holding bracket 8 (FIG. 1) or can be slidable in a guide track 31 (FIGS. 5, 6). In the essentially tangential position, the take-off guide eye is preferably spaced by a somewhat greater distance from the rim (23) of the drum than in the radially aligned position.

Claims21

Dependent claims

Thread supply apparatus for a textile machine, particularly for circular knitting machines, having

a holder (4) including means (5) for attaching the holder to the textile machine;
a thread storage drum (1) rotatable about an axis of rotation (1') and having a pull-off rim (23) journalled in the holder;
thread supply guide means (19, 20, 21) to guide the thread onto the drum so that, upon rotation of the drum, a plurality of storage windings (22) will accumulate on the drum, secured to the holder;
thread take-off guide means (11, 11a) to guide thread being pulled off the storage winding over said pull-off rim (23), secured to the holder,
and comprising,
support means (6, 6a, 8, 10) supporting said thread take-off guide means (11, 11a);
and adjustable attachment means (15, 31, 41) securing said thread take-off guide means to the support means in a plane (28) extending at right angles to said axis of rotation of the drum and selectively adjustably locating the thread take-off guide means in positions:
(a) at least two different angular positions of orientation with respect to said axis of rotation (1') of the drum in which positions the angle of the thread as it passes over said rim (23) upon being drawn off the drum and guided by the take-off guide means, is respectively different with respect to said plane;
and
(b) with respect to the distance of the take-off guide means (11, 11a) from the rim (23) of the drum.
