ABSTRACT:
A delivery device for continuous threads having a storage member to which the thread is fed in circumferential direction and from which it is withdrawn over its end and on which a given adjustable number of thread turns is stored as a withdrawal point, a light monitor which scans the circumferential surface of the storage member and controls the rotary drive for the feeding of the thread being provided in order to determine the number of thread turns. In order to make the thread tension uniform upon applying the thread to the storage member and in order to reduce the stresses acting on the braking device, the speed of rotation of the rotary drive is controlled as a function of the light intensity (amount of light) measured on the light monitor receiver.
