HIGH SPEED WATERJET LOOM FOR TEXTILE WEAVING
We created this website to give first-time buyers a clear and honest understanding of the JTM508. You can see what each system does, why the main options matter, and what to confirm before making a purchase decision.
Water Jet Looms
Shuttleless looms designed mainly for polyester, nylon, and other hydrophobic synthetic filament fabrics.
Specification Matching
We review the nominal reed space, pump and nozzle layout, shedding, let-off, take-up, motor, and color for each project.
Technical & Service Support
Our technical team can help with configuration questions, online consultation, after-sales support, and spare-parts planning.
Water Jet Loom
Waterjet Loom Model JTM508 for Polyester, Nylon & Synthetic Filament Weaving
Tell us what you plan to weave. JETMECH reviews the fabric type, finished width, weave structure, and target output, then explains which configuration is suitable and what should be included in the quotation.
Built for Long-Term, Stable Operation
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.

Machine Views & Specification Reference
Review the machine views first, followed by the mechanical and electrical systems.
02 / JTM-508
Drive-Side Access View
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.
03 / JTM-508
Electrical Control Side
The electrical-cabinet side provides access to the controller, wiring, and related electrical components. Keeping this area clear makes inspection, troubleshooting, and service easier.
04 / JTM-508
Warp-Beam Mounting & Let-Off Area
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
Heavy-Duty HT250 Gray-Cast-Iron Side Frames
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.
Frame / Transmission Side
Transmission-Side Cast Frame
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.
Frame / Opposite Side
Opposite-Side Cast Frame
The opposite-side frame and pentagonal support beams complete the rigid machine body. Center supports and approved anchor positions add installation stability.
SHEDDING SYSTEM OPTIONS
Shedding Models: NPW410 / NPW411 / NP5400D / LP409
This table compares NPW410, NPW411, and LP409 cam shedding systems with the NP5400D electronic dobby. Crank shedding is a separate option for simple weave repeats. Final selection depends on weave structure, required heald frames, nominal reed space, and target speed.
| Specification | NPW410 CAM | NPW411 CAM | NP5400D Electronic Dobby |
LP409 CAM |
|---|---|---|---|---|
| Nominal reed space | 190–360 cm | 190–360 cm | 190–390 cm | 190–360 cm |
| Supplier-rated maximum speed | 1,000 rpm | 800 rpm | 750 rpm | 800 rpm |
| Heald-frame pitch | 14 mm | 14 mm | 12 mm | 14 mm |
| Maximum heald frames | Up to 10 frames | 12 frames | Up to 16 frames | Up to 12 frames |
| Heddle length | 260 or 280 mm | 260 or 280 mm | 330 mm | 260 or 280 mm |
| Shed opening | 56–113 mm | 56–113 mm | 58–142 mm | 56–113 mm |
| Pattern-repeat capacity | 12 picks | 12 picks | 12,800 picks | 12 picks |
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
Mechanical systems for stable, efficient, and long-lasting weaving
01 / Weft Insertion
Water Pump & Brass Fittings
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.
02 / Selvage System
Planetary Leno Selvage Device
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.
03 / Transmission System
NSK / NACHI Main Drive Bearings
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.
04 / Fabric Width Control
Six-Ring Temple Assembly
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.
05 / Weft Insertion
CNC-Machined Nozzle Holder & Guide Assembly
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.
06 / Water Removal
Aluminum-Alloy Water-Suction Blower
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
Intelligent control, precise feeding, and efficient direct-drive systems
07 / Machine Control
English-Language HMI & Diagnostics
The HMI displays speed, production data, alarms, and key operating parameters. Integrated diagnostics support efficient setup, troubleshooting, and routine operation.
08 / Weft Preparation
Electronic Weft Feeder
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.
09 / Weft Insertion
Water-Jet Solenoid Valve
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.
10 / Timing Control
Main-Shaft Angle Encoder
Mounted on the main-shaft timing assembly, the encoder reports shaft angle to the controller for synchronized feeder release and water-jet actuation.
11 / Warp & Cloth Control
Electronic / Mechanical Let-Off & Take-Up
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.
12 / Main Drive
5.5 kW Direct-Drive Main Motor (X-Motor)
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.
