tsudakoma looms

Specifications

RJW408 water jet loom:

The RJW408 weaves a wide range of fabrics from general clothing to thick value-added fabric.

The RJW408 has the lowest running costs, while keeping quality high.

The RJW408 is a water jet loom on which high-tech machanics and electronics are harmonized for true user-friendliness.

High speed:

Robust frame structure, Tsudakoma’s original sturdy double-sided box frame reduces vibration at high-speed operation. Because of this reduces vibration, the filling insertion and beating motion are much more stabilized which keeps fabric quality high.

Its main drive is contained in an oil bath to achieve stable high-speed operation. For a 190cm-wide loom weaving taffeta, speed increasing 10% compared with previous models.

Energy conservation:

1 outstanding economy, the rush-start motor instantly provides ultra-high torque only at loom start. The RDP uses the storage blower and can change its force depending on the yarn. These all contribute to great energy savings and smaller running costs.

2 stable filling insertion ability & soft picking, a new nozzle with improved convergence of jetting water allows stable operation of the loom even with less water jetting. It does not damage the warp during high-speed operation. Thus, fabric quality is improved and water consumption is reduced.

Versatility:

1 stable cloth fell, the robust frame structure, rigid let off and take up stabilize the cloth fell position and the weavable range is increased from thin to middle-thick fabic, and from low to high density fabric. Even with dobby motion, vibration is low, so the RJW408 can easily weave fabrics of complicated or unbalanced construction.

2 soft filling insertion at high speed, the filling insertion angle is enlarged by improvement in the beating curve. Filling insertion for thick and twisted yarns or SHINGOSEN is more stabilized and value-added fabric can be woven. Furthermore, weaving greatly improved even on a fabric with an unstable warp shedding pattern or which easily generates warp looseness during weaving.

User-friendiness

Main parts feature:

PF-type nozzle : an advanced P-type nozzle is used. Jetting water focuses further, stable operation with a small shed opening and less water is realized, and soft picking gentle on the warp and the filling-is attained even at high-speeds. It is especially useful to improve fabric quality of one-color taffeta weaving at high speeds. The stabilizer lasts much longer.

RDP-A measuring & storage device : as the maximum tension given to the filling is relatively low, quality fabric weaving is assured even at higher speeds with single nozzle use. In addition to regular yarn fabrics, those value-added fabrics such as twisted, taslan, nep or loop yarn are easily woven.

Electronic, optical, and self-control: the simple and small optical feerler accurately detects and yarn-from raw to high twist and fine to thick-to realize stable high-speed operation.

Rush-start motor: the ruch-start motor provides an ultra-high torque start and effectively prevents stop marks and first pick looseness. Large capacity electromagnetic brakes directly connected to the crankshaft accurately stop the loom at the programmed position.

FDP-H measuring & storage device: the new easy-to-operate FDP-H with computer control reduces tension of the stored yarns and conducts stable storage for delicate fine yarn, non-twist yarn, thick yarn, and high-twist yarn. Aujustments for the feeder head are simplified with the software and the hardware . Response speed is also improved. The release sensor and the sensor to detect yarn breakage on the feeder are also provided for best fabric quality.

2C nozzle separator: the filling tip protruding from the nozzle is stabilized to prevent entanglement of the filling yarns.

Fabric quality and let off: the reinforced gearbox and two-roll let off respond to light to ultra-heavy fabric, up-grading fabric quality. The MLO mechanical let off uses a ring cone-type speed changer and the easy-to-operate ELO electronic let off minimize stop marks.

Stable cloth fell: the precise take up device keeps a stable cloth fell to assure higher adaptability for a wider range of fabrics. The ETU electronic take up system does not require change gears, and it incorporates a stop mark prevention mechanism to control the cloth fell. It’s easy to weave both high and low density fabrics.

WBS weft brake system: the WBS effectively reduces peak tension at the end of filling insertion and makes the crimping effect of high-twist yarn fabric even. It also prevents tight or loose pick of textured fabrics.
