ABSTRACT:
A thread storage device having a storage drum (1) from which a supply of thread can be withdrawn overhead through a thread take-off eye (5) which is arranged spaced from the end (1') of the drum and having a brake ring (8) which is arranged coaxial to the storage drum, with brake member (2) acting on an edge region (4) of the drum on the thread take-off side, the axial position of the thread take-off eye (5) and brake ring (8) being adjustable relative to the storage drum. In order to be able to effect a finer adjustment of the braking action, the thread take-off eye (5) is displaceable in axial direction relative to the brake ring (8) in such a manner that, with constant brake action of the brake member (2) which merely prevents ballooning, the thread application (alpha 1, alpha 2) on a radially inwardly curved section (3) of the drum is adjustable.
