(54) Yarn splicing device and yarn winding machine


(57) A yarn splicing device (14) includes an untwisting pipe (82) for acting airflow on a yarn end to untwist the yarn end; and a dedicated dust collector (80) for collecting yarn wastes generated by the untwisting. The dust collector (80) includes a dust collecting chamber (42) for temporarily accommodating the collected yarn wastes. The dust collecting chamber (42) is formed with a yarn waste introducing port (42a) opened towards the untwisting pipe (82), a yarn waste discharge opening (47) for sucking and discharging the yarn wastes in the dust collecting chamber (42) to outside, and an air vent filter (45) arranged at a position facing the yarn waste discharge opening (47).
