Abstract: An apparatus for automatically supplying cops to a winder includes a cop-feeder which moves along a track of the winder, the cop-feeder including means for stopping same in registry with each winding unit of the winder, storage for cops, a cop-feed-out section, a charging section for transferring cops from the feed-out section to the magazines of the winder, and means for grasping a yarn end and transferring same to a fresh cop. The apparatus also can determine whether a magazine has its full supply of cops, selectively halting the cop-feeder only at magazines which have an incomplete complement of cops and supplying the needed number of cops to the magazines. The travelling mechanism permits the feeder to stop only at every other magazine during a run in one direction along the track and at the remaining magazines on the return trip. Provision is made for feeding cops to magazines while the magazines are in rotation. The method of operating the apparatus includes provision for varying the speed of the feeder along the track so that the cop feeder is brought to rest gently in position for feeding cops to a magazine in need of replenishment, and the use of an air current for positioning yarn ends, all without manual intervention.
