Features Toyota’s Original Compact Yarn Spinning System
Toyota is proud to present the RX240NEW-EST, the latest ring spinning
frame based on the highly acclaimed RX240NEW and equipped with a new
compact yarn spinning system.
The RX240NEW-EST is equipped with Toyota’s original compact yarn spinning
system. The condensing device, consisting of a suction slit and perforated
apron, provides smooth collection of fleece fibers and stable spinning of
highly even yarn with low hairiness. A simple four-spindle structure ensures
excellent operability and easy maintenance.
Stable Spinning of High-Quality Yarn
A condensing device, consisting of a suction slit and perforated apron, has been added onto the
roller section to enable smooth collection of fleece fibers and improved fiber parallelization. By
eliminating the spinning triangle, this device ensures stable spinning of high-quality yarn with low
hairiness and improved evenness, greatly contributing to yarn strength and elongation.
S P E C I A L F E A T U R
■ Smooth collection of fleece fibers thanks to a suction slit
and perforated apron.
■ Precise slip-free rotation of the perforated apron thanks
to positive drive of the top and bottom delivery rollers.
■ Inverter-controlled adjustable suction pressure.
The simple and rigid structural design concept
of the RX240NEW has been applied to this
compact yarn spinning system.
Suction Ducts (48 spindles per section)
Placing the suction ducts on the upper part of the roller stands
results in a simplified design and shortened piping route.
For easier handling, each 4-spindle condensing unit can be conveniently
detached and disassembled without using special tools.
■ Easily detachable condensing unit.
■ Perforated apron, driven by a bottom roller, is not
affected by top roller diameter.
■ Can be easily switched between compact and
■ Available for retrofit onto the RX240NEW.
The rollers are driven by a geared front-bottom roller and maintenance-free
carrier gear, resulting in a simpler structure.
From the Designer
When developing this compact yarn spinning system, we had to
keep in mind not only how to improve yarn quality but also how
to increase operability and make maintenance easier. We gave
the condensing unit an easy-to-handle, 4-spindle integrated
structure so that it could be readily detached from the main unit
and easily disassembled and reassembled during maintenance.
We also designed it so that it could be fitted onto the currently
available RX240NEW, turning it into a compact yarn spinning
frame simply by adding and exchanging some parts. We’ll continue
our commitment to developing better products by listening
closely to customer requests.

A Look at Toyota's Global Service Centers
Part 7: China
Shanghai Service Center
Sheng Xi He Qiao Dong, Nan Huan Road, Sheng
Zhen Town, Wujiang City, Jiangshu Sheng, China
Toyota has established 11 service centers around
the world to supply spare parts and provide aftersales
service, and is developing a system to
respond more quickly to customer needs. In this
section of each issue, we will introduce one of
these service centers. This issue, we take a look at
the Shanghai Service Center’s Wujiang Office.
The Wujiang Office of the Shanghai Service Center was established in June 2002 in the city
of Wujiang in Jiangsu Province. This makes it the third service base in China after
Shanghai and Shaoxing. The Shanghai Service Center, with its easily accessible and
convenient location, is in charge of such matters as installation supervision, after-sales
service and parts sales across the country. The Wujiang Office, on the other hand, is
aiming to be a service center close to the local area. It’s located in an area where many of
our customers have their mills so they can easily visit our office.
Presently, Wujiang is aiming to be one of China’s biggest textile industry centers,
producing high value-added fabrics. Many companies are reinforcing their plants and
equipment and pushing forward with technical innovation, and Toyota’s air jet looms are at
work at many of these mills. We expect to sell more air jet looms, water jet looms and
preparatory machines, making the role of the Wujiang Office more important.
The Wujiang Office currently has 5 full-time employees with help from some of
the staff of the Shanghai Service Center. Together they promptly handle customer enquiries
and offer full service including giving advice on installing textile machinery and after-sales
service for Wujiang and the surrounding areas.
Wujiang Office, Shanghai Service Center
Everyday is a Challenge!
After graduating from textile college,
I worked as a designer at a textile
machinery manufacturer. I joined
Toyota’s Shanghai Service Center in
1999. Currently, as manager of the
Shanghai Service Center, I am also
responsible for the Shaoxing and Wujiang Offices.
It’s been challenging to keep up with the advances in
technology. This year in particular, a few thousand air jet looms
were installed in the Wujiang area, making our jobs more
The service center’s main responsibilities are loom
installation and adjustment, after-sales service, spare parts
supply and repair. In the future, we hope to expand our
business range to include technical training for our customers.
Installation and After-Sales
Wang Shu Sheng
I joined the Shanghai Service
Center four years ago and have
since installed mainly air jet looms
across the country and provided
after-sales service. I came to the
Wujiang Office upon its establishment.
I still have a lot to learn compared to my Japanese
colleagues, but four years of experience has given me
confidence in my skills. Once a month, the Japanese
engineers in Shanghai hold a technical training meeting, and I
take the opportunity to raise my skills by asking questions
whenever I attend these meetings and whenever I accompany
Japanese engineers on visits to customers’ mills. I am well
aware that improving our skills leads to higher customer
satisfaction and will continue my efforts.
A Message From the Service Department
Mitsuhiro Iwasaki, Service Department Manager
First of all, thank you very much for your continued patronage of Toyota textile machinery. It is much appreciated.
Maintenance is an important aspect of ensuring consistent quality and long-term reliability. Here, we would like to bring to your attention a few important maintenance
items identified by our service technicians in the course of after-sales service. While these items are extremely basic, if neglected, they could become the source of
Air Jet Looms
Water Jet Looms
1. Proper preparation of the installation location and correct
equipment set-up are the two most important factors in
ensuring the safe long-term use of looms with
consistently high performance. Follow the instruction
manual carefully, especially in regard to foundation work
for the floor, electrical grounding connections, and the air
2. To ensure the reliability of components and maintain
excellent fabric quality, be sure to lubricate the beating
section and the let-off on a regular basis.
3. To achieve stable weft insertion, we encourage you to
periodically clean the reed. Allowing oil solutions or
sizing materials to build up in the reed dents will
severely degrade the consistency of weft insertions.
1. Shedding connecting rods in the crank
shedding mechanism should be lubricated each
time the loom’s beams become empty (every
10 days). This section is subject to a great deal
of water influx, and regular lubrication is
important to maintain adequate levels of grease
on friction surfaces.
2. It is important to check carefully for
overstretched motor drive belts. Press on the
belt to check whether the belt bows adequately.
Overstretching will not only reduce the service
life of the belts, but also shorten the service life
of motor bearings.
1. It is important that foundations be designed and built
to provide adequate floor loading capacity. This is
critically important in maintaining a flat floor surface
over the long term. Also, because even a tiny
eccentricity in rollers will have an impact on yarn
quality, it is important to check the levelness of the
2. To maintain consistent yarn quality, the
recommended change interval for spindle oil is
3. To bring the spinning machinery to a smooth stop, it
is important to adjust the main brake gap. Be sure to
make checking the gap a regular maintenance item.

Thai Rung Textile Co., Ltd.
Thai Rung Textile Co., Ltd. (TRT), the core of the TTI
Group, is located near Bangkok. Based on the slogan
“Achieve world standard and maintain it,” the company
has purchased Toyota machines every year for the past
several years. TRT currently has 38,000 spindles of
Toyota ring spinning frames, led by the 21,600 spindles
of RX240NEWs that it installed in 2001. These machines
spin T/C Ne45 yarn at an average machine speed of 20,000
rpm, among the fastest speeds in the world.
We spoke with the company’s managing director
Mr. Mongkol Mangkornkanok about how Toyota helps his
Achieve World Standard and Maintain It
Give us your thoughts on Toyota machinery.
We first started using Toyota RY4 ring spinning frames in
1985. The next year, we began
using FL16 roving frames, and in
1995 we purchased some RX220
ring spinning frames. All of these
machines are still in fine condition
and operating today.
Although we had some other
companies’ machines, we
decided to replace them with
Toyota machines. In 2001, we
simultaneously installed 21,600
spindles of RX240NEW ring
spinning frames along with FL100
roving frames, DX7A drawing
frames, and VC5 combers so we could spin polyester and
cotton blended yarns. With an average machine speed of
20,000 rpm, high yarn quality and productivity, ease of
maintenance, and durability of parts, we are very satisfied. In
short, choosing Toyota machines was the right decision.
How has Toyota’s after-sales service been
So far, we are satisfied with Toyota machines and after-sales
service. In fact, we are very pleased with the way Toyota has
promptly dealt with all matters, no matter how small, during
everything from machine installation to start of operation.
RX240NEW ring spinning frames at work
Do you have any requests for Toyota
Electricity costs are continuing to increase. Because the cost of
electricity accounts for 35% of spinning yarn, we would like to
see Toyota put more effort into developing machines that
consume less power. Also, because we must meet customer
needs for varying yarn counts, we would like to see Toyota
develop a system for fast and easy ring changes on any kind of
ring spinning frame.
