Researched and manufactured by assimilating Japanese, German and Formosan technology, with computer control system, Four-Shuttle Circular Loom of common practical type has many traits such as simple structure, convenience in operation and maintenance, low maintenance cost and high output etc. It is used for weaving 600D-1800D flat film; and the woven bags are widely used for packing cement, fertilizer, rice, flour, vegetables and other powder and granules materials. What should be mentioned particularly is non-oil rolling shuttle type, which can reduce energy consumption by 30% and make woven bags without oil pollution easy to coat and print.
Non-oil Rolling Shuttle and Track

Shuttle and Track Device
Non-oil Rolling Shuttle
With wheels below, shuttles of this type which need non-oil lubrication can reduce energy consumption by more than 30%; Woven bag surface is much easier to coat and print because there is no oil spills on it.
Electrical Control System
Change-speed Clutch Device
Transmission Device
With PLC control, this electrical cabinet is equipped with both automatic warp transmission device and broken weft detector.
This device is not only used for changing the density of wefts, but also for compensating broken wefts.
As shown in left picture, this linked rocking bar and arm (linked rocker) of small double-curved cam, have many traits such as flexible movement, low energy consumption, high resistance to friction and less quick-wear parts etc.
