Abstract (en)
Device for compensating the feed tension in four-for-one twisting spindles in which a doubled yarn is unwound from a rotating unwinder which rotates by following the unwinding of the feed yarn, in which the yarn re-ascends a re-ascending internal axial cavity in which a compensator device is inserted, which lengthens and shortens the run of the yarn at its interior as a function of its tension.
