ABSTRACT:
In a spinning method in which, after a bundle of fibers has been drafted, the fibers are introduced into a twisting device using an air jet. The fibers are formed into bound spun yarns by the twisting device and are wound on a package by a winding device. The spinning method includes the steps of arranging and doubling at least two spun yarns upstream from where a twisting torque applied to the spun yarn by the twisting device disappears, entangling the spun yarns by the residual twisting torque, and thereafter winding them on a package.
