Abstract: A method and an apparatus to wind a thread on a succession of reels carried by coaxial annuli provided with a clamp member to couple the thread to the reel, the switching-over of the thread from a filled reel to an empty reel being initiated after the detection, by way of a detector, of a predetermined angular position with respect to an associated anvil of the clamp member fixed on the annulus carrying the empty reel.This method and apparatus are for example used to wind electric insulated wire comprising a metallic core around reels.

Abstract: An apparatus and a method to wind a thread on a succession of reels, comprising two crown wheels or annuli having parallel and nearly horizontal axes, each of them supporting a coaxial reel, a traversing mechanism having a movable pulley displaced above the reels and able to feed the thread in regular layers, means being provided to cut the thread after the winding of a first reel and means to then ensure continuously the winding of the thread around a second empty reel.The apparatus comprise a first movable catch pin being positioned near the empty reel to ensure the gripping of the thread, to allow the cutting of the thread and the coupling of this thread around said empty reel, a second movable catch pin placed near the full reel to grip and maintain the thread perpendicularly to the axis of the full reel after the cutting of thread, and means to control the position of the catch pins at the end of the filling of said first reel.
