Abstract

PURPOSE: To provide the subject controller capable of actuating an auxiliary nozzle system on the accelerating side or the decelerating side when a detected value of flying characteristics of a weft yarn is outside an allowable dead zone width and always performing stable picking by arranging an auxiliary picking nozzle continuous to a main picking nozzle. CONSTITUTION: When the arrival timing of a weft yarn at the side opposite to the yarn feed is within an allowable dead zone width of about the reference timing, an auxiliary air system for an auxiliary picking nozzle arranged continuously to a main picking nozzle is kept in a closed state to carry out the picking operations by jetting with the main picking nozzle using compressed air of a main air system. If the flying timing is outside the allowable dead zone width for some reasons, the auxiliary air system on the accelerating side or the decelerating side is opened by an output of a comparison discriminator to perform operations so that the flying characteristics are within the allowable dead zone width by the auxiliary nozzle. Thereby, always stable picking can be carried out with good responsiveness even if the flying state of the weft yarn is remarkably changed.
