摘要： A reel side yarn suction nozzle (4) comprising an arm (28) movable from at least one rest position to at least one working or suction position, the arm (28) being fluidly connected to a suction source to create a suction airflow, the arm (28) terminating with a suction slit (32) having a rectilinear configuration elongated along a transverse direction (T-T). Said suction slit (32) is provided with a deflector (44) and/or a comb (48); the deflector (44) is oriented so as to induce a pinch of the air flow generated between the associated reel (12) and the suction slit (32), accelerating the air current and thereby facilitating the gripping of the free end of the yarn on the reel side (24); the comb (48) comprises a roughened surface (64).

摘要： A drawing apparatus (4) for air spinning machines with multiple feeds, comprising at least a first and a second introducer element (8,12), independent of each other, so as to feed simultaneously at least two separate webs (Nl, N2), an air spinning device (16) adapted to spin said webs (Nl, N2), a drawing device (24) placed between the introducer elements (8,12) and the air spinning device (16), comprising a plurality of pairs of drawing rollers (28), comprising one drive roller (32) and one idle roller (36) per pair. At least one drive roller (32) of a pair of said drawing rollers (28) is mechanically split into a first drive roller (40) which intercepts a first web (Nl) and a second drive roller (44) which intercepts the second web (N2). The first and second drive rollers (40,44) are operatively connected to separate drive means so that they can be operated at different speeds of rotation, to perform different degrees of drawing of the two webs (Nl, N2) intercepted by said first and second drive rollers (40,44), wherein said first drive roller (40) is associated with a first idle roller (52) and said second drive roller (44) is associated with a second idle roller (56), said idle rollers (52,56) being mechanically separate from each other. A thrust device (60) is associated with said first and second idle rollers (52,56), which preloads each elastically in contact with the first drive roller (40) and the second drive roller (44), respectively, in a symmetric and equivalent manner so as to apply the same preload to said drive rollers (40,44).

摘要： A drawing and spinning apparatus of mixed yarns for air spinning machines with multiple feeds, comprising at least a first and a second introducer element, an air spinning device suitable for spinning said textile fibre webs, a drawing device, interposed between the introducer elements and the air spinning device, an air spinning chamber for weaving together said textile fibre webs, an introducer nozzle shaped to receive the webs from the drawing device into respective insertion channels and introduce the webs into the spinning chamber according to a longitudinal feeding direction, wherein said spinning chamber comprises two air jets oriented in a direction substantially tangential to the webs entering the spinning chamber, so as to intertwine said webs together and obtain a single yarn leaving the spinning chamber. Advantageously, with respect to a cross-section plane perpendicular to said longitudinal feed direction, groove bottoms of each of said two insertion channels of the webs into the chamber are aligned along a segment which is offset by an eccentricity with respect to a geometric centre of the chamber itself, through which a symmetry axis of the spinning chamber passes, said eccentricity being less than 5% of a maximum diameter of the spinning chamber.
