ABSTRACT:
A yarn splicing device for piecing spun yarns without knots. It contains a yarn splicing chamber and a small pipe through which fluid flows, at a distance from the yarn splicing chamber. The small pipe serves to receive a yarn end and to prepare it for the splicing process. The small pipe has a roughened inner surface which makes contact with the yarn end in a battering manner. In the process for the yarn end preparation, the small pipe is traversed turbulently by a fluid. The yarn end is battered by the turbulent flow against the roughened inner surface of the small pipe until the yarn end is free of twist.
