METHOD AND APPARATUS FOR REMOVING WRAPPED YARN GROUP ON PACKAGE BOBBIN END AND CONVEYOR LINE THEREFOR

摘要

A method for removing a wrapped yarn coil (Y) of an initial yarn portion of a package (P); said wrapped yarn coil (Y) being wound on a bobbin (B) while being gripped by a slit-like groove (G) formed on the bobbin end along a peripheral circle of the bobbin (B), and being followed by a transfer tail (T); comprising steps of severing the wrapped yarn coil (Y) at a position (C) on the bobbin end in which the slit-like groove (G) does not exist, while holding the severed ends (Ya,Yb) of the wrapped yarn coil (Y) by suction, gripping the severed ends (Ya,Yb) by grippers (23), and removing the wrapped yarn coil (Y) from the slit-like groove (G) along the periphery of the bobbin (B) while rotating the grippers (23) in the twisting direction so that a twist is imparted to the wrapped yarn coil (Y) held by the grippers (23).
