ABSTRACT:
A delivery device for continuous threads, having a storage member (5) to which the thread passes in circumferential direction and from which the thread is withdrawn over head, on which member a given adjustable number of thread turns is stored as storage quantity between point of feed and point of withdrawal, a light monitor which scans the outer surface of the storage member and controls the rotary drive for delivering the thread being provided in order to determine the turns of thread. In order to achieve a high output construction which is insensitive to disturbance, the storage member (5) has a light guide, the end surfaces (35', 35") of which are exposed towards the outer surface (6) of the storage member, one end surface (35') of each light guide facing the transmitter (29) of the light monitor and the other end surface (35"), staggered in circumferential direction of the storage member (5), facing the receiver (30) of the light monitor.
