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.
An apparatus to wind a thread on a succession of reels, comprising two annuli with parallel and practically horizontal axes, each carrying a coaxial reel, a reel traversing mechanism provided with a pulley movable over the reels for feeding of the thread around the reels in regular layers, means for cutting the thread when one reel has been filled up, means to then ensure without stopping the winding of the thread around a second empty reel, comprising 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 said full reel after the cutting of thread, and means to control the position of said catch pins at the end of the filling of said first reel.
A method to wind continuously a thread on a succession of reels, the thread near the empty reel being tangential to the flange of that reel, said thread being gripped near said empty reel and pushed backwardly to allow its coupling to said empty reel and to allow its cutting, the remaining slack portion of the thread being wound on the filled up reel after being maintained along a trajectory nearly perpendicular to the axis of said filled up reel.
