Abstract
There is disclosed a thread-feed device having a stationary winder drum storing a supply of thread which can be wound-on by means of a rotatable winder arm and removed overhead from the winder drum, and having a first monitoring device which automatically controls the rotary movement of the winder arm as a function of the length of the supply of thread formed. Within the region of the withdrawal end of the winder drum there is arranged a second monitoring device which gives off a first signal to a control unit upon each pass of the thread through its monitoring region during the withdrawal of the thread. The control unit counts the first signals and, as soon as their number reaches a predetermined adjustable value which corresponds to the desired required length of thread, there is given off a second signal by which a thread gripper is actuated so that the thread-feed device delivers precisely measured lengths of thread, such as required for instance for the filling insertion on jet looms.
