<p>Method and apparatus for picking up an end yarn (Ya) so as to fix the same on a yarn package (P) comprising picking up an end yarn (Ya) from a yarn package (P) by a suction means (19) so as to hold the end yarn therein in a drawn state, inserting an end yarn handling bar (10) between the held end yarn (Ya) and the package surface, revolving the end yarn handling bar along the package surface while maintaining the bar beneath an outermost layer yarn (Yb) connected to the end yarn (Ya) until a layered portion is formed, in which the end yarn (Ya) held in a drawn state coincides with the outermost layer yarn (Yb), and ejecting a jet of pressurized fluid (28) onto or in the vicinity of the layered portion so as to entangle the end yarn (Ya) with the outermost layer yarn (Yb) so that the end yarn (Ya) is fixed on the package (P). Method and apparatus for treating a package end yarn when the end yarn is released from an entangled portion, in which the end yarn (Ya) is entangled and fixed with an outermost layer yarn (Yb) of a package (P) comprising drawing the outermost layer yarn so as to float the same above the package surface with both ends thereof continuing to the package (fig.10b), severing the floating outermost layer yarn from the package at a portion on one side thereof (fig.10c), rotating the package in the unwinding direction so as to draw the other portion of the outermost layer yarn (fig.10d), severing the outermost layer yarn from the package at a portion on the other side thereof (fig.10e), and rotating the package in the winding direction so as to withdraw a fresh end yarn. <IMAGE></p> |
