Applying to high speed、thick fabric weaving JS21N series air jet loom enrich and extend weaving applicability, strong frame structure and stable weft beating motion ensure super high speed and weaving thick fabric.  Advanced electronic control technique Jinshuai with independent intellectual property rights developed the electronic control system of new generation air jet loom by absorbing international advanced air jet loom ele-control technique. This system uses 32 bits multi-CPU computer control, realized intelligent、networking、serialization、high efficiency、high reliability, and enhanced good man-computer interface、simplified operation、auto setting、self-diagnosing and monitoring. Electronic control system is the kernel technique of air jet loom. Only advanced electronic control system can make advanced air jet loom.  Weft Insertion Adopt famous electromagnetic valve abroad to realize high speed and  stable weft insertion under low air consumption with optimization.  ETU electronic take-up motion Take-up motion rotates synchronously with loom, and controls weft beating density by using AC servo motor through computer controlling. It can change weft density on touch screen instead of changing gear. According to cooperation with electronic let-off, it makes machine running easier and prevents stop.  CONSIDERABLE MAN-COMPUTER DESIGN ■ Large touch screen                                ■ Equipped large touch screen, which makes easy operation, and enhances the man-computer communication.                                                                It has self diagnosis, show the problems when loom stop.                                                                ■ Users can mend parameters of loom by touch screen.                                                                ■ Users can save settings into computer by memory card.                                                                ■ The stop position of loom can be confirmed by length of cloth, in order to keep cloth inspection going well                                                                  ■ It can analyze every operator’s performance.  Super weft insertion ▲ Adaptable electronic yarn accumulator Yarn accumulator developed by our company can adapt feeding speciality in working circle automatically. It can reduce tension fluctuate to the lowest level to make weft insertion smoothly. Weft detector uses two  feelers. It could detect weft shortening or missing pick, broken pick and fold pick. ▲ High frequency solenoid valve Air-powered original part uses new famous high frequency solenoid valve from America. It speed up the channel of weft insertion, achieves high speed and stable weft insertion under low air consumption.  ▲ Enough picking with high speed Narrow breadth loom uses 4-link weft beating which is highly praised in high speed adjustability, for wide breadth loom, it uses 6-link weft beating, which is flexible in weft insertion, to achieve stable weft insertion. ▲ WBS weft arrester WBS reduces much of the peak tension when picking ends, to avoid broken pick and loose pick. It uses new photoelectricity part to inspect the flying state of weft, realized trig timing of high definition on control area. It applies to wide breadth loom with big peak value tension. It can be set through programming easily, and has the function of pulling back which can avoid producing fault. ▲ Main subsidiary nozzle The weft is accelerated by low air pressure, in order to avoid weft damage. It can keep running stably even on high speed or wide range weaving. We not only have the same standard style with linkage of main nozzle, we also have the absolute controlling style that can free set the timing of jet.      ▲ Stretching nozzle Stretching nozzle is effective to fabric that is easy to loose pick. It uses compressed air to hold weft to avoid loose pick.  High quality weave      ★ Two independent electronic selvedge motion[ESM] because two motors can set the hatch angle freely, the operation of cutting and weaving range’s adjustment is improved. In addition, the weaving speed、the leno selvedge quality and the reliability of working parts are highly improved.　 ★ Super startup motor      This loom adapts super startup system, produces high output torsion when starts, to strengthen the fist pick. It eliminates stop marks, and improved fabric quality.  ★ Control of fist pick Because of the first pick, loom speed is slow while staring, atp to produce long yarn and bad yarn end. JS21N air-jet loom adopts the computer to control the pick time, long yarn and bad yarn are prevented. ★ Cloth fell following motion To let-off immediately after stop, it prevents the slowly reversal reed touches cloth fell, which eliminates stop marks. It auto resumes the tension of begin setting, in order to beating at the right close fell. ★ Selection of stop-start angle It can set the stop and start angle freely according to the fabric type and position of stop mark. ★ Adjustment of let-off quantity when start To set let-off quantity freely according to different stop condition can effectively prevent stop marks.  ★ Start of picking of first shuttle It doesn’t need to beat again while restart, can directly feed, which prevents stop marks when weaving thick fabric.      ★ Upper installed temple To deploy profile guiding perch near cloth fell with two upper installed temple on two sides, it makes the cloth fell stable and improved fabric quality. In addition, the lower part of the guiding perch can set the position of subsidiary nozzle, which enlarged the weaving range.      ● ELO electronic let-off motion Electronic let-off motion uses measure sensor of tension roller to test actual tension, through the AC servo motor dealt with the computer to control warp beam let-off while the warp beam diameter can be compensated automatically, so let-off precision extremely high. It can keep warp yarn tension, to insure all kinds of the fabric quality.      ● Double beam rolls let-off synchronously Double beam roll synchronously electronic let-off motion can be adapted on wide breadth loom, for clients convenient to use trim yarn sizing  equipment on hands.      ● ETU electronic take-up  Using high nature AC servo motor which controlled by computer, make the ETU and loom running at same speed, control the density of beating, the density of beating can be established on the iT-board, do not need to change the gear wheel. Through operating with the moving in succession of ELO, it can effectively prevent stop marks. ● Hatch device      ☆ Positive cam It is suitable for weaving heavy and width fabric shedding motion. It runs at high speed and steady warp yarn shedding with auto parallel heald function. ☆ Dobby shedding It can choose dobby device for mechanical/electric, negative/positive and down installed/upper installed.      ● Strong frame structure Used strong box wall board on both sides, beam roll gear with large diameter and positive let-off warp beam. It can beat stable with low vibrating under high speed. It ensures the loom with high-speed, high accuracy to adapt high density fabric weaving requirement.   ● Ensure the complete lubricate cycle system  　Bath oil lubrication is used inner transmission gear box. Center lubrication is used to the other parts of the loom.
