Abstract

Per la produzione di un filo con l'aiuto di un dispositivo di filatura ad estremità aperta, presentante un rotore di filatura 1, le fibre vengono alimentate su una superficie di guida di fibre (40) di forma anulare, allargantesi in direzione del rotore di filatura (1), e trasportate mediante una corrente d'aria in direzione perimetrale della superficie di guida di fibre (40) e, lungo un percorso avvicinantesi a forma di spirale al rotore di filatura (1), condotte nel rotore di filatura (1). In questo caso, nella direzione di trasporto di fibre, dopo lo sbocco di uscita (20) del canale di alimentazione di fibre (2) viene aspirata aria dalla superficie di guida di fibre (40). Questa corrente di aria di aspirazione è opposta alla direzione di trasporto della corrente di fibra/aria, uscita dal canale di alimentazione di fibre (2), e muoventesi in direzione perimetrale lungo la superficie di guida di fibre (40). Le fibre però, mediante utilizzo della loro inerzia, vengono condotte, in continuazione del loro percorso precedente, nel rotore di filatura (1), ove esse vengono deposte sotto forma di un anello di fibre, per la successiva legatura, nell'estremità del filo estratto continuamente, che viene asportato dall'interno del rotore di filatura (1). La superficie di guida di fibre (40) in questo caso è supportata in maniera non girevole.(figura 1).For the production of a thread with the help of an open-end spinning device, having a spinning rotor 1, the fibers are fed onto an annular-shaped guide surface of fibers (40), widening in the direction of the spinning (1), and transported by a current of air in the perimetral direction of the fiber guide surface (40) and, along a spiral approaching path to the spinning rotor (1), carried in the spinning rotor (1 ). In this case, in the fiber transport direction, after the outlet outlet (20) of the fiber feed channel (2) air is drawn in from the fiber guide surface (40). This intake air stream is opposite to the direction of transport of the fiber / air stream, which emerged from the fiber feed channel (2), and which moves in a perimetric direction along the fiber guide surface (40). The fibers, however, through the use of their inertia, are carried, in continuation of their previous path, in the spinning rotor (1), where they are deposited in the form of a ring of fibers, for subsequent binding, in the end of the thread continuously extracted, which is removed from the inside of the spinning rotor (1). The fiber guide surface (40) in this case is supported in a non-rotatable manner (figure 1).
