The thread delivery device includes a guide drum 15 with a thread bearing surface 26 which extends with continuous curvature from an inwardly tapering initial location 25 to an outwardly widening end region 27. The bearing surface 26 is provided, at least in the region of the initial location 25, with a friction- promoting covering, and the thread 23 is fed to the drum 15 by way of a rigid thread guide member 24 which is aligned with the initial location 25 of the guide drum 15 and is drawn off from the drum 15 by way of a thread guide member 28 which is likewise fixed in operation. When thread tension is lacking on the removal side, the thread looped around the guide drum 15 slips into the region of smaller drum diameter and is no longer co-moved by the guide drum 15. <IMAGE> |
