Abstract
In a yarn splicing operation on a ring spinning machine wherein a broken end of yarn is drawn into a suction tube in position for splicing, the suction is reduced after the yarn is in position to avoid damage or destruction of the yarn as it is being held by suction. The reduction in suction is accomplished by the opening of a bypass, the restriction of the tube or a reduction in the speed in the motor of the suction pump.
