The double-twist is established directly from drawing the material from a point exterior to the spindle towards an interior point where storage of yarn occurs. The first twist is produced by an anti-balloon ring in a radial channel to the support of spindle and cranked with respect to the spindle shaft, and the second twist is produced at the exit to the cranked radial channel, by a pair of anti-friction roffers which carry the yarn through a thread guide and to other thread guides mounted in a distributor. - While the support of spindle is fixed, while the elbow of the spindle is gyratory and transmits its movement through an endless belt to a primary shaft.
