<p>A thread supply device for a textile machine, which device includes a drum on which a thread is wound to form an intermediate thread storage, and from which the thread is withdrawn over one end of the drum for supply to the textile machine. A brake means is disposed adjacent the withdrawal end of the drum and acts on the unwinding thread for imposing a braking effect thereon. The braking means acts progressively on the unwinding thread as it moves peripherally relative to the drum for either increasing or decreasing the braking effect on the thread, depending upon the relative peripheral direction of movement of the thread.</p> |
