Introducing the

RX240NEW-EST

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.

Main Features

High Quality

■ 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.

Simple Structure

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.

Condensing Units

For easier handling, each 4-spindle condensing unit can be conveniently

detached and disassembled without using special tools.

Delivery Rollers

Suction device

Excellent Operability

■ Easily detachable condensing unit.

■ Perforated apron, driven by a bottom roller, is not

affected by top roller diameter.

Condensing unit

Flexibility

■ Can be easily switched between compact and

conventional spinning.

■ 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.

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.

Wujiang, Jiangsu

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.

Everyday is a Challenge!

Service Manager

Sun Xiao

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

challenging.

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.

Service Engineer

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

serious problems.

Air Jet Looms

Water Jet Looms

Spinning Machinery

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

supply system.

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

machinery itself.

2. To maintain consistent yarn quality, the

recommended change interval for spindle oil is

4,000 hours.

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.

Bangkok

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

business.

TRT’s Motto

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

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.
