ABSTRACT:
This invention is related to a yarn piecing apparatus of a spinning machine arranged with a holding member (12) that holds the parent yarn (Y') which is inserted in the hollow spindle (6) of the spindle member (5) which is seperated from the nozzle member (2), at a predetermined tension so that it does not rotate due to the rotating air current from the nozzle member. As the parent yarn (Y') inserted in the hollow spindle (6) of the spindle member (5) which is seperated from the nozzle member (2) is held by the holding member, there is no rotation of the parent yarn (Y') by the rotating air current and consequently, fibers can be reliably attached to the parent yarn (Y') and the success rate of yarn piecing can be increased.
