Abstract
The nozzle structure has a control valve in which a channel for the admission of air opens at an acute angle into the guide channel for a weft thread for a weaving machine. The channel can be adjusted so that the admitted air is directed for deceleration of the thread counter to the insertion direction. The control valve can be rotated 180.degree. so that the admission channel is in an opposite position so that the admitted air then flows in the insertion direction of the weft thread and can be used for threading a broken weft thread into the nozzle structure.
