  • Patent number: 4727715
    Abstract: A piecing process is provided for an open-end friction spinning apparatus of the type including movable friction surface members forming a yarn-forming zone therebetween. A friction surface driving device for moving the friction surface members during operation and for interrupting the movement of the friction surface members is also included in the apparatus. The spinning apparatus further includes a yarn end orientation member for orienting a yarn end during the piecing process. The process includes placing a yarn end into the yarn-forming zone when the rollers are stopped. The friction surface members are started such that the yarn end is prevented from being pulled too deeply into the yarn-forming zone by the yarn end orientation device. An apparatus for carrying out this process is also provided.
