With each weaving operation

With each weaving operation, the newly constructed fabric must be wound on a cloth beam. nba jerseys This process is called taking up. At the same time, the warp yarns must be let off or released from the warp beams. To become fully automatic, a loom needs a filling stop motion which will brake the loom, if the weft thread breaks.[1]
For all this to happen, the yarn has to be prepared. The weft, or filling must be wound tightly on the correct size pirns, quills or bobbins. Weaving happens at great speed so the yarn must be at the correct tension when it leaves the shuttle. mlb jerseys The warp passes through the heddles which stretch it at each pick, and through the reeds which are abrasive. The warp is thus sized, that is coated with a mixture that can include china clay and flour, to give it extra strength and to act as a lubricant. It is dressed or wetted while passing through the loom. The warp, hundreds of ends of yarn rolled in parallel, comes on a wooden beam.ed hardy jeans Before weaving can commence each end must be passed through the heddles and reeds: a process known as looming.[2]
An automatic loom requires 0.125 hp to 0.5 hp to operate.
Francis Cabot Lowell traveled to Great Britain from the United States in 1810 to study the textile industry there. He paid particular attention to the workings of the power loom, a device for which was not available in North America. He memorised the plans for the machine, as the British had banned the export of the new technology. On returning to Boston, he put together a group of investors, and sought the assistance of a master mechanic named Paul Moody. By 1815, Moody had built the first power loom in Waltham, Massachusetts.[10]
In 1881 James Henry Northrop emigrated to the USA from Keighley,rolex watches replica Yorkshire, England he worked for the Draper Corporation of Hopedale, Massachusetts. His inventions leading to an automatic "weft replenishment" loom revolutionised the weaving industry. Some 700,000 "Northrop" automatic looms were sold worldwide.
Draper's strategy was to standardise on a couple of models which it mass produced. The lighter E-model of 1909 was joined in the 1930 by the heavier X-model. Continuous fibre machines, say for rayon, which was more break-prone, needed a specialist loom.cheap cartier watches This was provided by the purchase of the Stafford Loom Co. in 1932, and using their patents a third loom the XD,ed hardy bags, was added to the range. Because of their mass production techniques they were reluctant and slow to retool for new technologies such as shuttleless looms.
