Abstract

Il dispositivo comprende un unico mezzo frenante a sviluppo circolare, tipicamente un corpo troncoconico (12), sostenuto da mezzi elastici (13), coassialmente e frontalmente al tamburo (T) dell'apparecchio e sollecitato da detti mezzi in impegno di contatto elastico contro il tamburo stesso lungo una circonferenza (Cl) di esso minore di quella massima. Il filato (F) scorre tra detti tamburo e mezzo frenante e si estende dal punto di contatto di essi lungo un percorso inclinato rispetto all'asse del tamburo (T) per cui la tensione prodotta dal mezzo frenante sul filato ammette una componente assiale che si scarica sul mezzo frenante ed è equilibrata da detti mezzi elastici. L'aumento della tensione sul filato produce o tende a produrre, per effetto del corrispondente aumento della sua componente assiale, il distacco del mezzo frenante ed è equilibrata da detti mezzi elastici. L'aumento della tensione sul filato produce o tende a produrre, per effetto del corrispondente aumento della sua componente assiale, il distacco del mezzo frenante dal tamburo e la corrispondente autoregolazione dell'azione frenante.(Rif. Fig. 3).The device comprises a single circular development braking means, typically a frusto-conical body (12), supported by elastic means (13), coaxially and in front of the drum (T) of the apparatus and urged by said means in engagement of elastic contact against the drum itself along a circumference (Cl) of it less than the maximum one. The yarn (F) flows between said drum and braking means and extends from the point of contact of them along a path inclined with respect to the axis of the drum (T) so that the tension produced by the braking means on the yarn admits an axial component which it discharges onto the braking means and is balanced by said elastic means. The increase in the tension on the yarn produces or tends to produce, due to the corresponding increase in its axial component, the detachment of the braking means and is balanced by said elastic means. The increase in the tension on the yarn produces or tends to produce, due to the corresponding increase in its axial component, the detachment of the braking medium from the drum and the corresponding self-regulation of the braking action (Ref. Fig. 3).
