GA731-II GRIPPER LOOM
【Loom Picture】
 
【Weaving range】
This model loom can weave all kinds of nature fiber (such as cotton, wool, silk, flax, ie) and various manmade and chemical fibers. It can weave single fabric, double-panel fabric and more panels. It is most suitable to weave wide width dyed fabrics.
【Characteristic】
1、Compact structure,easy operating, and easy to change fabric design. High automatic, wide weaving range, ie.
2、Adopts minicomputer controlling system, has the functions of warp stop motion, weft break stop motion, fault inspection, pick-finding, LCD screen,etc.
3、Shedding device: low built positive mechanical/electronic dobby.
4、Weft insertion adopts double rapier grippers and single side weft supply, conjugated cams drive rapier bands and clamp type central exchanging. All the process of insertion is controlled by optimized conjugated cams, make the movement of rapier more perfect, and ensure the weft tension steady-going, weft handing over credible and working stable during high-speed running.
5、Beating unit adopts slay which is driven by conjugated cams, using inertia to beat, the impact and power consume can be decreased. The beating conjugated cams have the precision as same as the insertion cams’, the cams drive short slay, can ensure the beating strength for high-density fabrics and heavy fabrics.?
6、Positive let-off adopts double-adjustment system to ensure the warp let-off tension steady-going.
7、Take-up consists of worm wheel, worm and chain wheel, it drives the cloth roller continuously.?
8、8-color selection at will. (Max.)
9、4kw main motor drives all the units through an electromagnetism clutch. Electromagnetism clutch works with electronic controlling system to control the loom start, stop, inching and so on.
10、Leno selvage. Options: tuck-in device, heat melt device.
11、Bath oil for main transmission, enforcedly injection for swaying shaft bearing, or sealed bearing if without bath oil.
