Abstract

A yarn splicing device comprising a twisting nozzle (73) adapted to twist yarn ends; and a twisting airflow supplying mechanism (42) adapted to supply compressed air to generate a twisting airflow with respect to the twisting nozzle (73) and to switch a whirling direction of the twisting airflow and/or to switch a generating region of the twisting airflow, wherein the twisting airflow for twisting the yarn ends is generated in the whirling direction and/or the generating region in accordance with a twisting condition of the yarn to be performed with a yarn splicing operation by a control on the twisting airflow supplying mechanism (42).
