    Abstract: The thread storage and supply arrangement comprises a storage drum having a peripheral thread storage surface onto which is to be wound a succession of adjoining turns of thread, the thread storage surface comprising a thread infeed region at one axial end of the storage surface and a thread outfeed region at the other axial end. A thread infeed structure located at the thread infeed region guides thread onto the peripheral storage surface to form a succession of adjoining turns of thread. A thread outfeed structure located at the thread outfeed region feeds off the storage drum thread which is to be pulled off. The peripheral storage surface, at the thread infeed region thereof, curves radially inward in the direction from the infeed to the outfeed region and, at the thread outfeed region thereof, curves radially outward in the direction from the infeed to the outfeed region.
