This machine is an equipment of round braiding bag made with filament of polyporopylene and polyethylene. This factory has prepared and developed common-tyoe and high-speed-type which have been awarded many patents ,942096444.4?95200402.x?96212248.3?99206601.8 ? 99219360.5. High-speed -type is developed on the basis of common - type ,has obvious synthetic economic benefits. A rapid speed ,less parts and easy to operate, so a machine can saves about 10000 yuan than common-type according to power rate and wages. Shuttle takes high -quality steel plate into model, plates hard chromium and delay a service life. Install seven wheels on shuttle body, add three wheels on the basis of four wheels, turn the sliding friction of common type into the rolling fricton, so delay a service life of shuttle wheel and lower the operating power of motor ,otherwise for high-speed machine set yp frrquency controller of motor speed specially to establish speed lf mainshaft. Screen round loom makes better on the basis of high-speed specially to establish speed of mainshaft. Screen round loom makes better on the basis of high -speed loom to take crissrross motion and weave into netbah which is an ideal packaging bag for vegetable and fruit.942096444.4?96109762.0?95200402.x?96212248.3? 99206601.8?992199360.5?
