Abstract

Alimentatore di trama da cui il filo di trama viene prelevato "a defilè" da una riserva su un tamburo, sulla estremità del quale, a monte di un guidafilo di uscita agisce un dispositivo di frenatura a elemento frenante troncoconico con flessibilità differenziata e supporto a tazza a fondo aperto, l'elemento frenante comprendo listelli sottili affiancati. Nell'elemento frenante detti listelli si riuniscono nella circonferenza maggiore, in una fascia a superficie liscia e rigorosamente continua di impegno della estremità del tamburo, mentre sono liberi e appoggiano liberamente nella circonferenza minore, contro l'interno della periferica del supporto a tazza. L'elemento frenante è associato al supporto a tazza libero di deformarsi e/o di compiere limitati movimenti in ogni direzione. Il guidafilo di uscita è separato dall'elemento frenante e tenuto fermo, coassiale al tamburo, durante la frenatura.
