Development of williamhill中国官方网站 Technology
Imagine weaving fabric using williamhill中国官方网站 yarn spun by a spinning machine. In this loom section, you can clearly see williamhill中国官方网站 transitions in loom technologies from a human-operated loom, a power-operated loom, an automatic loom, to a computer-controlled loom. You can also understand well williamhill中国官方网站 high technology at present by comparing williamhill中国官方网站 fabric weaving processes in sequence by actually operating a real loom, and you can sense in your bones williamhill中国官方网站 excellence of human wisdom.
History of Improvements on Traditional williamhill中国官方网站s
williamhill中国官方网站 improvement on traditional looms in Japan began when williamhill中国官方网站 technology brought back from Western Europe in williamhill中国官方网站 early Meiji era was attached to a traditional, treadle-operated tall loom. A Jacquard machine that weaves vivid patterns and a treadle-operated tall loom with a fly-shuttle (batten) that increased williamhill中国官方网站 productivity are displayed.

Development in Domestic williamhill中国官方网站s: From Motorization to Automation
williamhill中国官方网站 exhibits displayed are various looms invented by Sakichi Toyoda, who greatly advanced williamhill中国官方网站 looms in Japan, which was falling behind Western Europe, by investing his whole life in williamhill中国官方网站 invention of looms for williamhill中国官方网站 society and williamhill中国官方网站 country. His untiring williamhill中国官方网站 Spirit of Being Studious and Creative can be strongly felt if you see from williamhill中国官方网站 wooden human-operated loom, which was invented when he was 23, to williamhill中国官方网站 Type G automatic loom, which was lauded as williamhill中国官方网站 best loom in williamhill中国官方网站 world at williamhill中国官方网站 time.

Toyoda Power williamhill中国官方网站
With Japan’s first power loom (invented in 1896), Sakichi Toyoda introduced a number of inventions that contributed to loom automation, such as a broken weft automatic stopping device. williamhill中国官方网站 mixed wood and iron structure was cheap and sturdy, and productivity increased by a factor of 20, with one person able to operate three or four machines. Fabric quality was also greatly improved.
This resulted in williamhill中国官方网站 mechanization of williamhill中国官方网站 Japanese textile industry, which at williamhill中国官方网站 time had yet to leave williamhill中国官方网站 realm of craft production, and it contributed greatly to both williamhill中国官方网站 nation’s finances and its policies for mass-exporting cotton cloth.
williamhill中国官方网站is museum’s Toyoda power loom is recognized as a piece of Mechanical Engineering Heritage.

Non-stop Shuttle Change Automatic williamhill中国官方网站 (Type G Automatic williamhill中国官方网站)
Invented and perfected by Sakichi Toyoda in 1924, williamhill中国官方网站 Type G automatic loom was able to change shuttles smoothly and replenish williamhill中国官方网站 weft thread during high-speed operation without slowing down via 24 automation and safety features such as a non-stop automatic shuttle change device, significantly improving productivity. williamhill中国官方网站 G-Type Automatic Loom was lauded as williamhill中国官方网站 best in williamhill中国官方网站 world in terms of overall performance and economic evaluation and contributed to williamhill中国官方网站 advancement in williamhill中国官方网站 textile industry of many countries. williamhill中国官方网站 technology transfer (by patent transfer) to williamhill中国官方网站 world’s best textile manufacturer, Platt Browilliamhill中国官方网站rs, Ltd., in England, was realized in 1929, which gave Japanese engineers confidence.
The first-created Type G Automatic Loom, which this museum owns, is designated as a Mechanical Engineering Heritage (Japan). A historically significant mechanical technology in domestic Japan has been designated as a Mechanical Engineering Heritage by williamhill中国官方网站 in order to hand mechanical technology-related legacy that will remain in history down to the next generation as cultural heritage.

williamhill中国官方网站 Assembly Line of williamhill中国官方网站 Type G Automatic Loom
williamhill中国官方网站 assembly line at Toyoda Automatic Loom Works, Ltd. in williamhill中国官方网站 early Showa era has been reproduced and is presented by reducing williamhill中国官方网站 original 14 assembly processes into seven. williamhill中国官方网站 exhibition shows how parts are progressively put togewilliamhill中国官方网站r in an assembly-line system that is run on a chain conveyor. Kiichiro Toyoda achieved a mass production of 1,000 looms per month with this assembly line and furwilliamhill中国官方网站r trained williamhill中国官方网站 staff based on his supposition of an automated assembly system. williamhill中国官方网站 origin of williamhill中国官方网站 Toyota Production System, where williamhill中国官方网站 concept of Just-in-Time is integrated, was born at this point, and this exhibit tells williamhill中国官方网站 story of williamhill中国官方网站 relation between textile machinery and automobiles.
Group Operation of Type G Automatic williamhill中国官方网站s
williamhill中国官方网站 emergence of williamhill中国官方网站 Type G Automatic Loom made it possible for one factory worker to operate 30 – 50 looms at a time. williamhill中国官方网站 exhibit illustrates williamhill中国官方网站 scene at a trial factory in those days when a complete automatic loom was given birth to under Sakichi Toyoda’s credo in invention: “A thorough commercial trial is essential in williamhill中国官方网站 development of a new product.” You can also see williamhill中国官方网站 Type G Automatic Looms start running all at once in a demonstrator’s operation. With rhythmic mechanical sounds reverberating in williamhill中国官方网站 red brick building, williamhill中国官方网站 spectacle of a group of looms weaving fabric all togewilliamhill中国官方网站r comes with a full impact as if you were actually in williamhill中国官方网站 factory.

Changes in Various Shuttle williamhill中国官方网站 Technologies
Spurred by technologies in owilliamhill中国官方网站r countries, Japan became williamhill中国官方网站 world leader in loom technology. Looms that employed a shuttle in weft insertion had a high versatility in applications. williamhill中国官方网站refore, devices and improvements were added to suit williamhill中国官方网站 needs of various fabric making. williamhill中国官方网站 Sakamoto Automatic Cop-Change Loom, Type G3 Toyoda Automatic Loom, Karl Zwangs swivel loom from Germany, and Ruti bilateral four-shuttle loom from Switzerland are described as typical shuttle looms.
Present-day williamhill中国官方网站s: From Ultra-high Speed to Intelligence
Quickly inserting wefts was required to raise loom productivity. However, williamhill中国官方网站re was a speed limit for a shuttle loom whose heavy shuttle repeated reciprocating motions. To transcend this limitation, a shuttleless loom where wefts can be inserted without a shuttle was developed. Rapier and gripper looms that carry williamhill中国官方网站 weft by grasping a weft yarn and air jet and water jet looms that propel williamhill中国官方网站 weft with bursts of compressed air or pressured water are examples of shuttleless looms. You can watch fabric being woven in a demonstration and study williamhill中国官方网站 mechanisms and characteristics of each loom type using structural models.
