Abstract
A method and apparatus remove a faulty weft thread from a beat-up edge or cloth fell by pulling its leading end with a pneumatic thread removal device, which adaptably takes into account the thread characteristics and particularly the twist of the thread. The method maintains the twist of the thread by generating a simultaneously sucking and rotating airflow in the thread removal device, wherein the direction of rotation of the flow is controlled to coincide with the direction of the twist of the weft thread. The pneumatic thread removal device includes an injector nozzle with at least two gas flow inlet ports oriented to respectively cause oppositely rotating suction flows through the nozzle, and a controllable throttle valve to selectively direct a gas flow to the inlet ports.
