<p>Twisting device for bobbin winding car, so prearranged as to give a false twist to the sliver (6) leaving the drawing frame (2) - or from a derived machine - for cross-wound bobbin winding, constituted by a twisting element consisting of a spiral (10) rigidly anchored to a movable active-twisting unit of revolving-funnel type (16), causing, in this relationship of cooperation, said sliver to be compactly and firmly wound on the collecting bobbin and to be always subject to a same tension value both in the intermediate winding points, and in the winding points positioned at the ends of the above said bobbin under way of formation.</p> |
