Winding Introduction The winding process is the division between the group of processes described as spinning and those described as weaving. At first sight, winding machinery appears to fulfil no purpose other than a simple transfer of yarn from one package to another. This is however, an oversimplification of the winding process. Winding is basically transferring a yarn from one type of package to another. This simple definition may make the winding sound like a trivial process; however, it is an important and necessary process that performs the following functions especially for ring spun yarns. • Winding produces a yarn package that is suitable for further processing. Ring spinning produces small packages …show more content…
Thin and thick places, slubs, neps or loose fibres on the yarn are cleared during winding and, thus the overall quality of the yarn is improved. Staple yarns require this clearing operation most because they may have these kind of faults more often. The increasing use of newer spinning technology resulted in a situation where the old concept of yarn clearing and package quality now has become a part of spinning process rather than a part of a separate winding process. Objectives of Winding • To wrap the forming yarn on a package in a systematic manner or to transfer yarn from one supply package to another in such a way that the latter is adequately compact and usable for the subsequent operations. • To remove the objectionable faults present in original yarns. Winding requirements • The fault level in the yarn must be reduced to an acceptable …show more content…
The user may not have a free choice in the sort of package he unwinds but he does have a choice when it comes to the package he builds. Consequently, it is necessary to cnosider in some detail the structures which can be built to withstand reasonable handling and use. Transferring yarn Most of the textile winding operations deal with the conversion of ringframe bobbins into cones or cheeses. As a result of high warping speed in modern machines direct use of ringframe bobbins in warping will necessitate package change after very often. This will reduce the running efficiency of warping machine. Therefore, ringframe bobbins are converted into bigger cones or cheeses. Ringframe bobbins are also not useable as transverse or weft packages because they have empty core which will require bigger size of the shuttle and thereby causing problem in shedding operations. Therefore, for shuttle looms, pirn winding operations are carried out to manufacture weft packages from cones. Motion & Withdrawing Motion Two basic motions are required for effective
“The Industrial Revolution was another of those extraordinary jumps forward in the story of civilization” (Stephen Gardiner). One of the major parts of the industrial process has to do with metal production. Welding has been incorporated into the framework of metalworking. Welding dates back to the middle ages where forge welding processes were used to make tools and weapons, commonly known as blacksmiths. It is known that the Egyptians used forms of welding to make gold tools, jewelry, and decoration. During the 1800’s a new process was formed by using carbon electrodes to form an arc. This was done by Sir Humphrey Davy, which carried on to become Carbon Arc Welding and the most used process during the late 1800’s. As time evolved so did the
The packaging aspect involves gathering the communication materials, combining them into one package, and distribution. The materials can be used by employees to answer some basic questions they may have. If their questions can not be answered, they are encouraged to contact the human resource department (of Capital) or Arbor.
But there were also issues in packaging that had to be resolved: development of the packaging design was one of his primary concerns at this time. Ultimately, there will have to be manufacturing procedures in accordance with corporate policies and standards: capital equipment selection and procurement, installation of this equipment and startup.
The principle advantage of the ring spindle was it` s operation by unskilled female staff, whereas the traditional mule required skilled (mostly male) operatives, thus saving on labour costs. The disadvantage was that the ring needed more expensive cotton to make a given `fineness` or `count`. Given this information, replacement of old existing technology should only be undertaken if the total cost of the new technology is less than the variable cost of the old technique.
The first thing to consider is the process of cleaning and coating of the boards. This particular process involves the set-up of the machines, the loading of the boards, and the actual cleaning and coating of the said boards by the machines.
In the story, Like a Winding Sheet, author Ann Petry depicts a tale of a hard working man and his internal battle with anger, self-realization and the daily woes of being black in America. At the end of the story his wife, Mae Johnson, becomes the recipient of the anger Johnson has held so. close to him. Through symbolism, style, and mood, Petry allows the character to embrace the world around them, leaving me questioning the subject of violence, racial discrimination, and hate. Although Like a Winding Sheet is a short story, it bears witness to a generation of men, who during this time, had very little voice and power
From spinning and weaving that was done in households for domestic consumption, went to the Spinning Frame developed by Richard Arkwright. With this, production in Britain of cotton textile, between 1770 and 1790, in 20 years alone the output increased tenfold.
Weaving is a common thread among cultures around the world. Weaving is a way of producing cloth or textile. Today we have machines that weave large-scale textiles at cheap prices. Production of cloth by hand is rarely engaged in today’s Westernized societies. Not many people are thinking about how the fibers are actually constructed to make their clothes. However, in other cultures across the world the tradition of weaving still exists. By comparing three cultures that continue weaving as a part of their tradition we can see similarities and the differences between them. The reasons that each culture still weaves vary, as do the methods and materials. The desired characteristics of the cloth also vary around the world as each culture values different aesthetics.
Gearboxes are a universal piece of equipment for applying power from a driving unit to a driven unit. They require very little maintenance besides oil changes, and bearing grease. This allows them to last longer than V-belts, chain drives, or open gears before they need to be replaced. With the many different configurations of gearboxes, they can be used for many different applications for everyday life and industrial use.
A blanket that a million of thread are weaved together is tight and stronger than a piece of a thread, which it’s weak and it can be cut at anytime. When a pieces of thread are weaved together, they turned to the blanket that is stronger and warmer.
During the Industrial Revolution, the textile industry received high demand for its cloth goods. However, the production of such goods was very slow. As demand rose, the need for a faster, cheaper, and more efficient way of producing enough cloth goods became more urgent. Thus, inventors began developing new ways to produce cloth goods. One of the best examples was English inventor James Hargreaves. Hargreaves invented the spinning jenny, a device in which spinners would use his right hand to quickly spin a wheel to rotate spindles and spin 8 threads around 8 spindles attached to a wooden frame. Since each spinning jenny could spin several threads simultaneously, the device dramatically increased the rate at which cloth was produced and the quantity of cloth that was made. This allowed for the textile industry to meet the large demand for cloth goods of the time and enhance their method of produ...
Maher (1999) states that the different packages on the market have different strengths in different areas, it is important for the customer to recognise this and select the package with the strengths that are appropriate. Only when top management have reached consensus on what the business requires, should package vetting and selection begin.

In case of a horizontal axis wind turbine, the plane of the rotor rotates such that the wind direction is perpendicular to it. This allows the wind to flow around the blades, thus causing them to rotate around the hub. As the blades rotate, this causes a rotation of the shaft which is then coupled with a gearing system to step up the speed of the generator. The generator converts mechanical energy into electricity which is passed on to the grid.
From 2005 the textile segment has been made up of 2 companies, transforming raw materials into fabrics, from spinning to finishing and ennobling. Handicraft product quality and technological research development characterize this business segment which works with internationally recognized names of the apparel and fashion industry.
