ABSTRACT:
An apparatus for forming transfer tail windings on a bobbin includes a bobbin having an annular groove adjacent one end thereof which in the case of a tapered bobbin, would be located adjacent the larger diameter end. The annular groove is provided with a radially disposed wall and an inclined wall which is tapered outwardly from the radial wall toward the end of the bobbin. A spring-biased pivoted yarn regulator extends transversely across the path of the yarn from the spinning unit to the deepest portion of the annular groove on the bobbin and is provided with a yarn guide portion opposite the inclined surface of the annular groove. A centering disc engages the end of the bobbin adjacent the annular groove and is provided with a plurality of yarn engaging notches spaced about the circumference thereof. The yarn from the spinning unit is directed over the yarn guide portion of the yarn regulator around the bottom of the annular groove and over the top of the annular groove back toward the yarn regulator. Upon initiating rotation of the bobbin, the free end of the yarn will be shifted laterally into engagement with a notch on the centering disc to wrap the free end of the yarn diagonally about the inclined surface so that subsequent windings will overlie the free end of the yarn. After a predetermined number of turns, the yarn regulator will be pivoted against the bias of the spring to release the yarn from the yarn guide portion whereupon the winding of the yarn upon the main portion of the bobbin will commence.
