Approach into Increasing the Yield of the Assistant Nozzle

In order to increase the yield of the assistant nozzle,through the analysis of the performance and the process of the assistant nozzle in the weft insertion system of conventional air-jet loom,it is pointed out that the head profile of the nozzle and the electrode specification,manufacturing process of the nozzle are the main factors in relation with the yield.Some advice is given as below:① improvement of the angle of the upper mould and the radian of the bottom mould of the mould for proper cavity;② good configuration of the electrode specification for better coarseness Ra of the nozzle against the slow air speed or for better nozzle speed effiency;③ proper manufacturing process is designed acc.to the diffent nozzle profile with the help of the electric device without cutting force,and more,improvement of the clipping device and the manufacturing process is very important.The product performance and the production efficiency is improved a lot and the yield of the product increases from 75% to 90%.
