Abstract (en)

Device for controlling and stabilising the feed tension in four-for-one twisting spindles wherein a rotating unwinder rotates by following the unwinding of the feed yarn that re-ascends an internal axial cavity up to a deflecting bell-shaped transmission element, from which the inner balloon of the four-for-one twisting spindle begins, where the deflecting bell-shaped element is rendered idle with respect to the unwinder below.
