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.
