The method of making self-twisted fibrous product from at least two strands relates to spinning. According to the method, each one of a pair of continuously fed strands is acted upon by a torque imparting to the strand an alternating twist. Then the strands are united or plied, so that they untwist about one another, forming the self-twisted product, the strands, as they are thus untwisting about one another, having positively applied thereto a torque in the direction of their untwisting, with the frequency of the variation of the direction of the torque equalling the frequency of the variation of the sense of the twist imparted to each strand. As a result, reliable engagement of the strands is attained without acting thereupon by friction, which minimizes the drift in space of the point of engagement of the strands, whereby the length of the portions devoid of the twist is reduced and stabilized, and the twist of the strands is fully utilized in the twist of the product.

The distributing device for supplying compressed air to the jet nozzles of swirl chambers relates to apparatus for making a self-twisted product. The distributing device comprises a stationary hollow housing with apertures and a passageway for supplying compressed air, and also a rotary distributing member of a cylindrical shape, in the form of a sleeve with a bottom, mounted in the internal space of the housing with a gap left therebetween, this gap permanently communicating with the compressed air supply passageway. The open end of the distributing member faces the compressed air supply passageway and, the member having passages made in the cylindrical wall thereof, periodically communicating through the apertures in the housing with the jet nozzles of the swirl chambers, to supply compressed air thereinto. The disclosed structure of the distributing device enables to increase the reliability of its performance and to provide for the stability of the flow of the process of obtaining the self-twisted product.
