JCA810 High speed air jet loomWith the rigidity of the machine frame and top beam further strengthened, the whole machine is of desired stability, beating mechanism optimized, structure further improved. Beating may be done with four-or six-shedding levers and with the six-shedding lever, the warp yarn has longer opening hours, facilitating weft inserting more suitable for wide weaving thus extending its weaving scope.Optional shedding type: crank, cam, dobby, jacquard, it has the feature of electric let-off, electric take-up, variable weft density weaving, automatic stop in case of broken yarn, double weft sensors, electronic measuring, electronic feeder, and electronic control for detection of selvage yarn breakage, weft catching and side yarn making the operation more user-friendly.Optimized rear beam structure: rear beam structure has been improved with more sensitivity for varying of the warp tension. Rear tension roller bracket is installed outside of the machine frame facilitating installation and maintenance.This series has the advantage of strong machine frame, fitting for weaving dense and fine fabrics. Since their let-off, take-up, and detecting are all electronically controlled, it can effectively eliminate the problem of unexpected machine stoppage, mechanical stop, product defects of broken yarn and short weft, thus enhancing weaving quality.[Main Technical Parameters]● Reed space: 150,170,190,230,280,8500px● Max weft density: 1235m/min (depending on fabric type)● Applicable range for weft and yarn: 7 to 60tex (80 to 10Ne) (optional accessory available for fiber less than 10).
