Abstract
During servicing of a spinning machine station by the piecing apparatus, the yarn positioning means establishes a generally U-shaped yarn line and brings the lowermost bight section of such line into desired association with the yarn delivery rolls at the spinning machine station. Rotatable members form the bight section of the yarn line and then transport the same, while the members occupy rotative positions effective to prevent lateral movement of the bight section, to a location closely adjacent the delivery rolls. The members then are rotated to other positions wherein they permit and guide lateral movement of the bight section toward a free end of one of the delivery rolls. When a piecing-aid device is present at the spinning machine station, the piecing apparatus includes a mechanism for imparting movement to a movable component of the device, and the positioning means of the apparatus includes means for associating parts of the U-shaped yarn line with the foregoing and other components of the device.
