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.
