Abstract
A cabling and yarn double-twisting spindle having pneumatic assistance for a threading up of the yarns to be handled by the spindle is provided. The spindle includes a shaft rotatably supportable in a support hub on a spindle bank. The shaft has a central, axially extending shaft bore, and package top. The package top is secured against rotation and has a hollow spindle axial portion disposed in communication with the spindle shaft bore. A pressurized air injector effects threading up of a yarn component delivered via the hollow spindle axial portion of the package top with another yarn component delivered via the spindle shaft bore, and includes a pressurized air supply conduit in the spindle shaft such that the pulse of air injected by the air injector is operable to produce a suction flow in the hollow spindle axial portion of the package top and in the spindle shaft bore.
