Title: Method of and apparatus for making a doubled yarn
IPC: D02G3/36
Filed: 1981-05-14
Abstract: An apparatus for making a doubled yarn draws a core yarn off a core-yarn supply, pulls the core yarn longitudinally in a travel direction along a yarn path, and drafts the core yarn longitudinally along this path. A tube through which the yarn passes longitudinally extends along the path downstream of the drafting station has relative to the yarn-travel direction an upstream portion and a downstream portion. A current of air is passed longitudinally in the travel direction through the upstream tube portion and another current is passed longitudinally opposite the travel direction through the downstream portion. Thus upstanding fibers are first laid against the core yarn to be integrated into it as same twists in the upstream tube portion and any remaining fibers are laid back against it so that a winder yarn can be wound around the core yarn immediately downstream of the tube to bind in these fibers too.
