Method of automatically piecing up a yarn in an open-end spinning
machine and an open-end spinning machine for carrying out the same
摘要:
A method of automatically piecing up a yarn in an open-end spinning machine by rotating the draw off rollers and winding drum in a direction opposite to their normal rotating directions; rotating the feed rollers according to a predetermined program so that the feed rollers begin to rotate after an end of the yarn is moved back into the spinning rotor where the moved back yarn is pieced up with the newly spun yarn; rotating both the draw off rollers and the winding drum in their normal rotating direction, and starting the traverse motion of the traverse guide, which takes place after the pieced joint reaches a contacting line formed between the winding drum and the cheese.By utilizing this method and machine, the number of yarn breakages occuring during starting operation is decreased.
