Being additionally provided with bobbin feeler on described bearing, bobbin feeler and weft yarn stretch pipeline and are positioned at the homonymy of bearing, and weft yarn stretches the end of pipeline and offers spy latitude mouth, and bobbin feeler is just to visiting latitude mouth.
Described bearing is provided with yielding rubber pad towards the side of draft nozzle, and the back side of yielding rubber pad and reed fits.
Described weft yarn stretches pipeline and includes weft yarn entrance, weft yarn dominant draft section and the weft yarn long section of survey successively along weft yarn draw direction, weft yarn entrance is bend pipe, weft yarn dominant draft section and weft yarn are surveyed long section and are straight tube, the jet hole of draft nozzle towards and the axis of weft yarn entrance be all mutually perpendicular to the axis of weft yarn dominant draft section.
The jet hole of described draft nozzle is vertical flat.
Described draft nozzle is connected with source of the gas by steam line, and steam line is provided with drawing-off electromagnetic valve.
Described bar of moving with the hand is straight pin.
Owing to have employed technique scheme, having the beneficial effect that acquired by this utility model
1, the draft nozzle in this utility model cooperates with weft yarn stretching pipeline, it is possible to produce bigger pull strength, it is achieved the bending drawing-off of weft yarn, and completely without intercepting reed, has stopped to intercept the produced waste of reed and unnecessary waste.
