The development of the rapier loom began in 1844, when John Smith of Salford was granted a patent on a loom design that eliminated the shuttle typical of earlier models of looms. [3] Subsequent patents were taken out by Phillippe and Maurice in 1855, W.S. Laycock in 1869, and W. Glover in 1874, with rigid rapiers being perfected by O ...
Weaving a tapestry on a vertical loom in Konya, Turkey A Turkish carpet loom showing warp threads wrapped around the warp beam, above, and the fell being wrapped onto the cloth beam below. A simple handheld frame loom. Weaving is done on two sets of threads or yarns, which cross one another.
With each weaving operation, the newly constructed fabric must be wound on a cloth beam. 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.
Both the Jacquard process and the necessary loom attachment are named after their inventor. This mechanism is probably one of the most important weaving innovations, as Jacquard shedding made possible the automatic production of unlimited varieties of complex pattern weaving. The term "Jacquard" is not specific or limited to any particular loom ...
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. This was provided by the purchase of the Stafford Loom Co. in 1932, and using their patents a third loom the XD, was added to the range.
The process of weaving can be simplified to a series of four steps: the shed is raised, the shuttle is passed through, the shed is closed, and the weft thread is beaten into place. These steps are then repeated, with a different set of threads being raised so as to interlace the warp and weft. [1]
Doubling is a textile industry term synonymous with combining. It can be used for various processes during spinning.During the carding stage, several sources of roving are doubled together and drawn, to remove variations in thickness.
Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...
