ABSTRACT:
The present invention relates to a vortex air nozzle for yarn spinning from staple fibers, comprising an outgoing pair of drawing rollers, next to which is located an inlet chamber for the formation of free tails of fibers, with decreasing flat cross-section and inner grooved channels, ending with a cylindrical part, connected to the outgoing twisting chamber, supplied with tangential channels for air feeding, wherein in the inlet chamber for the formation of the free tails of fibers. The grooved channels are laterally formed in a drawing plane and reach the cylindrical outgoing part, as in the inlet chamber enters part of the circumferential surface of the lower drawing roller, as the cylindrical outgoing part is enveloped by the outgoing twisting chamber, which tangential openings are concentrically formed above the said cylindrical outlet part. The advantages of the present invention are that a sufficiently large number of free tails is created, and a control is ensured, up to the achievement of the false twist, and the fibers are strongly twisted by a potential vortex.
