Message from the General Manager of �the Textile Machinery Division

I have been newly appointed the general manager of the

Textile Machinery Division.�

�After joining the company in 1981, I started out with

textile machinery, then gained experience in a wide

variety of areas: logistics systems, Material Handling,

and Corporate Planning at the Head Office. However,

the textile-machinery business remains my favorite, and I

am delighted to be back here.�

��

�The textile industry in 2006 could be termed a year of

accelerated reorganization of global production centers

that began with elimination of the Quota system. Amid

this, China further strengthened its presence,

augmenting its ongoing quantitative expansion with a

change in course toward qualitative development as

well, and is now further solidifying its footing in the global

market. Growth of the textile industry in India as well

shows no signs of abating in 2007 or after.�

��

�Thanks to this market growth and the support of a

large number of customers both in Japan and abroad

over the course of many years, our JAT710 air-jet loom

that offers advanced functioning and has earned high

acclaim enjoyed annual sales of over 10,000 units last

year. This marked the first time in 69 years that we have

achieved sales reaching 10,000 units, ever since the

type-G shuttle loom that occasioned the launch of our

company sold some 12,000 units in 1937. I am deeply

grateful for the era-transcending support our customers

have shown us.�

��

�Far from resting on these achievements, however, we

at Toyota Industries intend to continue pressing yet

further ahead as we turn an even closer ear to what our

customers have to say.�

��

�In closing,I'd like to offer to you our best wishes for

your wealth and happiness. I look forward to having the

opportunity to meet you some day.

New Beating Motion / 50% reduction of machine vibration is achieved through lighter weight materials, hardening of beating-related components and applying balance weights across the full width. Furthermore, the short stroke offers higher fabric quality, co-usability of parts and longer parts life. The same reed can be used for both single and multi colors due to the common reed stroke.

New Beating Motion NEW

NEW

Use of the beating link and let-off / take-up controller from the dependable and proven JAT710, along with use of a new weft-insertion mechanism, make possible weaving that is gentle on the yarn, from light to heavy fabrics. The full complement of standard equipment, together with a diverse range of options that include our own innovative w-FIS and a ten-frame negative cam, make it easy to accomplish weaving fabrics of varying fineness, high-density fabrics, and more.

Versatility

High QualityOffering a short stroke and extended weft insertion time has allowed us to dramatically shorten the distance from the beating point to the heald frame. Beat-up performance is improved and shedding volume is reduced enabling the weaving of high-quality textiles while placing minimum strain on the yarn.

●Air-jet Loom Sales Surpass �　10,000 Units

Sales of our JAT710 air-jet loom for the year of 2006 (January through

December) achieved a figure of 10,206 units. This marked the first time in 69

years that annual sales exceeded 10,000 units, ever since the type-G shuttle

loom sold 12,104 units in 1937. Of this total, the share of units for China

accounted for more than 70%, which was greatly affected by the favorable

climate of the Chinese market and the large share we achieved there. In

China, aside from the growing demand for mixed-weave equipment in the

Wujiang region of Jiangsu Province, demand for air-jet looms for spun-weave

textiles was sustained at a high level in other regions as well. We also

received numerous orders from other markets, including India, Pakistan, and

Brazil, enabling us to achieve this figure of over 10,000 units.

●Contract for Sale of 51 Units of the RX240NEW-EST �　Compact Spinning System to the TIANJIN TIANFANG �　INVESTMENT HOLDING CO.,LTD

We have reached an agreement to

Key Points of Maintenance Information from the �Service Department

General Manager, Service Department�

Mitsuhiro Iwasaki

Thank you for your ongoing dedication to our textile machinery. Here, I would like to �tell you about some key points of maintenance.

Air-jet Looms

Part 16 - India

Corporate Office at Ludhiana

To prevent slippage of the drive

timing belt for a negative-cam shedding

system, be careful not to overtension the

belt. Overtensioning may shorten the life

not just of the belt, but of the tension-

pulley bearings as well.

1

The appropriate number of shedding

springs at the two ends of a negative-cam

shedding system varies according to the speed

of the machinery, the warp tension, the number

of warp ends, and the amount of shedding.

Make the setting for these while also monitoring

such factors as rope vibration beneath the frame.

2

Even when no damage is visible,

surface deterioration on the main-motor

belts, spindle tapes, and other such parts

of spinning frames can cause increased

slippage, which may adversely affect

spinning quality or related parts. Verify

correctness by conducting periodic

preventive maintenance.

1

The service life of the bolster

bearings for the spindle bolsters is greatly

affected by the oil level and the type of oil

used. Periodically replace the oil using the

type specified in the operation manual,

and also check the level via the gauge.

2

Adhesion and buildup of fly waste can

absorb grease and cause temperature rises,

reducing the service life of functional parts.

Periodic removal of fly waste is an important part

of maintenance. However, attempting to clean

away fabric or fales selvedge while the machinery

is in operation can result in entanglement or other

extremely hazardous situations. Be sure to stop

the machinery before attempting such tasks.

1

If attachment or removal operations

for harness frames or other accessory

parts are not performed under correct

conditions of tightness, the full service life

is not assured. Perform bolt tightening

using the specified tools and at the

specified torque.

semiconductor package substrates, and more. For automobiles,

the division is working to strengthen the development and

fabrication of such electronic components and devices as

compact, high-efficiency, and low-cost DC-DC converters for

hybrid vehicles and vehicle-mounted AC inverters that allow

household appliances to be used in vehicles.�

�In 1997, we established ST Liquid Crystal Display Corporation

as a joint venture with Sony Corporation to produce liquid-

crystal display devices. In 1998, we established TIBC

Corporation as a joint enterprise of Toyota Industries and Ibiden

Co., Ltd., to manufacture semiconductor package substrates.

Spotlight on the Division

The DC-DC converter for the Prius

converts the output from the 202-V

high-voltage battery to 12 V to

enable the use of auxiliary devices.

Through effective placement of the

filter suppresses radio noise and

achieves high efficiency. This

converter also allows idling to be

stopped while charging the auxiliary

battery, making it indispensable for

hybrid vehicles.

DC-DC Converter for �the Prius

This AC inverter delivers a maximum

output of 1.5 kW using the hybrid

car's high-capacity battery. It

enables electrical appliances that

consume a large amount of power

such as microwave ovens, vacuum

cleaners, and hair driers to be used

inside the vehicle, and can also be

used as an emergency power source

during disasters.

1.5-kW �AC Inverter

LCD panels using low-temperature

polysilicon thin-film transistor (TFT)

liquid-crystal displays offer fast response

and a vivid image. These devices also
