Abstract: An improved turret type yarn winding apparatus provided with means for regulating a running yarn passage when the bobbin change operation is carried out. This yarn passage regulating means is capable of utilizing for the conventional turret type yarn winding apparatus. When the full size yarn package is displaced from the winding position to the stand-by position while a fresh bobbin is displaced to the stand-by position to the winding position, the running yarn is firstly shifted to a position outside the traverse motion of the traverse mechanism, and thus shifted running yarn is forced to pass along a predetermined yarn passage maintained by the above-mentioned yarn passage regulating means so that the running yarn can be assuredly caught by a yarn catching means rotated together with the spindle whereon a fresh bobbin is mounted, at the winding position.
