MG9200 Max Airjet Loom
MG9200 Max is the upgraded airjet loom configuration built around JETMECH's patented beating shaft, also known as the sley shaft. This balanced shaft drives the reed with stable beat-up force, helping improve fabric consistency, reduce vibration, and support reliable high-speed weaving.
See how the patented beating system supports fabric consistency, lower vibration, and stable operation.
Patented System
The beating shaft is one of the most important systems in an airjet loom. It determines beat-up force, weft density uniformity, vibration level, and long-term weaving stability. JETMECH MG9200 Max uses a patented integrated beating shaft design for quiet, stable, and high-speed performance.
Designed for powerful, uniform beat-up force across the full fabric width.
The integrated beating shaft converts the loom’s drive motion into a controlled beat-up movement. Its coaxial, dynamically balanced structure distributes force across the reed width while limiting vibration at the shaft supports.
Coaxial geometry keeps the rotating mass centered through each weaving cycle.
The integrated shaft carries beat-up force continuously from the center to both ends.
The reed reaches the fell line with repeatable timing and force at production speed.
The integrated shaft body resists bending and torsional deformation, helping the reed maintain accurate alignment throughout repeated high-speed beating cycles.
The integrated shaft resists bending and torsion, keeping the reed accurately aligned during high-speed weaving.
Evenly distributed beat-up force supports consistent weft density across the fabric width, reducing visible bars and variation between woven sections.
Coaxial balance keeps the rotating mass centered, reducing vibration for steadier operation.
Dynamic balance limits vibration at operating speed, supporting repeatable reed motion, steadier running, and reliable fabric formation over long production periods.
Force is transmitted evenly across the reed width, supporting uniform weft density and stable fabric formation.
Lower vibration and smoother force transmission reduce stress on bearings, gears, and shaft supports, helping extend service intervals and equipment life.
Smooth force transmission lowers stress on bearings, gears, and shaft supports, helping extend equipment life.
This real-machine view shows the patented beating shaft installed across the full reed width. The integrated, dynamically balanced structure helps deliver uniform beat-up force with lower vibration during high-speed operation.
Check the core machine fit first, then review the frame option and real-machine service views.
Use these four points to check the basic machine fit before reviewing the systems below. Final reed width, shedding, nozzle/feeder layout, and drive package are confirmed from the fabric construction, finished width, number of weft colors, target output, and available compressed-air capacity.
The optional side-mounted tanks provide reserve-air capacity close to the loom, helping limit short-term pressure variation during high-speed weft insertion. The required quantity is matched to reed width, yarn, target speed, and factory air supply.
Drive-side and warp-side views show the service areas and overall machine structure.
This exterior view shows the drive-side structure, side covers, and service-access area. Internal cam configuration is confirmed separately in the machine specification.
The rear view shows the back frame, warp-beam mounting area, and rear service aisle used for warp preparation and routine maintenance.
Follow the operating sequence from control and drive through weft insertion, fabric formation, and maintenance.
Production settings are entered and monitored through the HMI. The servo main drive converts those commands into precise, responsive machine motion.
The 14-inch Smart interface brings operating status, production data, and parameter settings together on one screen for clear day-to-day control.
The X Moto servo main motor follows speed commands with strong low-speed torque and fast response, supporting smooth, controlled operation.
Pressure regulators, solenoid valves, the main nozzle, and relay nozzles work in sequence to carry the weft across the reed width with controlled pressure and timing.
SMC regulators set the main and auxiliary air circuits independently to match the fabric and target speed.
SMC solenoid valves control auxiliary-nozzle timing precisely; one valve serves two auxiliary nozzles.
Direct-mounted SMC valve control improves airflow response. A ceramic tip increases wear resistance and nozzle life.
Wear-resistant DLC coating provides more than twice the life of standard nozzles, reducing replacement frequency.
Heald frames, leno, cutting devices, and centralized lubrication support shed opening, selvedge formation, clean cutting, and scheduled maintenance.
Japanese NEWLIGHT frames provide accurate shedding with low inertia for reliable high-speed operation.
Electronic leno motion secures the weft at the fabric edge for a cleaner, more stable selvedge.
Electronic scissors match high-speed operation for clean cutting. A center cutter can be configured for wider machines.
The programmed pump supplies oil automatically, while the manifold distributes it evenly to key lubrication points for reliable long-term operation.

Review the machine views first, followed by the mechanical and electrical systems.
This overall view shows the loom body, operator-side arrangement, fabric path, protective covers, and the space to allow for installation and daily access.
This side brings together the warp let-off, fabric take-up, water-pump, and water-suction drives. Their coordinated operation helps maintain warp tension, even winding, consistent jet pressure, and effective water removal.
The electrical-cabinet side provides access to the controller, wiring, and related electrical components. Keeping this area clear makes inspection, troubleshooting, and service easier.
The rear structure supports and aligns the warp beam for smooth, even warp delivery. Adequate rear access also makes beam loading, setup, and routine service easier.
Heavy-Duty Frame Structure
The left and right HT250 gray-cast-iron side-frame assemblies weigh approximately 570 kg combined. Front and rear pentagonal connecting beams and eight floor anchors—four on each side—form a rigid base that helps maintain alignment and limit vibration during high-speed operation. Center supports and final anchor positions follow the approved installation drawing.
This HT250 frame supports the transmission, beat-up, and bearing assemblies. Its mass, beam connections, and floor anchoring help maintain alignment under continuous high-speed load.
The opposite-side frame and pentagonal support beams complete the rigid machine body. Center supports and approved anchor positions add installation stability.
A waterjet loom works in a humid environment, so long-term reliability begins with the machine body and its corrosion protection. JETMECH combines a heavy-duty body with 304 stainless-steel fasteners and protective covers. Phosphating, electrophoretic coating (E-coat), and three protective paint coats help resist corrosion and support dependable operation over time.

Quick guide: nominal reed space is the maximum supported machine width, while usable fabric width depends on the fabric and setup. Heald-frame count and pattern-repeat capacity indicate pattern flexibility; shed opening is the warp-yarn opening stroke.
The unit shown is NPW410. Values are supplier ratings for the shedding device, not guaranteed loom production speeds. Actual JTM-508 output depends on fabric construction, nominal reed space, weft yarn, shedding system, and machine settings.
Core Mechanical Systems
The water pump produces the controlled high-pressure pulse required for weft insertion. Pump model, plunger diameter, and brass fittings are matched to reed width, weft yarn, fabric construction, and target speed.
Installed near the fabric edge, the leno device interlaces selected warp ends to form a stable selvage. Its setup is matched to the fabric construction and required edge structure.
NSK or NACHI bearings are used for the main drive shafts inside the transmission gearbox. Their precision and durability support smooth power transmission and stable high-speed operation.
Positioned close to the cloth fell, the temple controls weaving width and helps reduce fabric draw-in. The ring and needle arrangement is matched to the fabric construction.
The precision-machined nozzle holder maintains nozzle position and jet direction. Pump setting, nozzle size, and timing are matched to reed width, weft yarn, and operating speed.
The blower removes residual water after weft insertion. A Ø65 mm SS304 suction pipe and stainless-steel tray form a durable, corrosion-resistant water-removal path.
Control & Drive Systems
The HMI displays speed, production data, alarms, and key operating parameters. Integrated diagnostics support efficient setup, troubleshooting, and routine operation.
The electronic feeder measures and stores the required weft length, then releases it at the programmed timing. Feeder quantity is confirmed with the customer according to the fabric design and required weft arrangement.
Installed in the water circuit, the valve selects the required jet line in step with the loom control. Its specification is matched to pump output, nozzle size, operating pressure, and the selected weft arrangement.
Mounted on the main-shaft timing assembly, the encoder reports shaft angle to the controller for synchronized feeder release and water-jet actuation.
Electronic let-off regulates warp delivery as beam diameter changes, while electronic take-up maintains programmed pick density. Mechanical let-off and take-up are also available to suit the production plan.
Mounted directly on the main shaft, the X-Motor eliminates the conventional main-drive belt; auxiliary belts may remain in other mechanisms. Fewer main-drive parts can reduce transmission losses, energy use, vibration, and routine maintenance.
