Tension-extractor device of the reel thread in the automated cutting of threads in sewing machines, characterized in that it is constituted by a. Rod with a loop through which an axis fixed to the machine's casing joins and on which it can swing, driven by an arm integral with a rod which, in turn, is articulated to the cutting mechanism, thus synchronizing the movements of the the moving blade and the rod; at the free end of said rod has a bend that forms a double fork with a narrow intermediate step to pull the thread of the spool both in the advance and in the return of the alternative tilting movement of the device.
