Abstract (en)
Device for automatically adjusting the inlet tension of the yarn in the inner balloon (B) in four-twist spindles, wherein the feeding yarn (F) is unwound from a feeding reel (11), passes through a rotary unwinder (50) and then enters into an inner axial cavity up to a bell-shaped deflecting element (51), from which the inner balloon (B) of the four-twist spindle (10) begins, where between the deflecting element and rotary unwinder a friction element is interposed which causes rotation speed variations in the bell-shaped deflecting element (51) and in the rotary unwinder caused by the tension variations of the yarn (F).
