A rapier loom is a shuttleless weaving loom in which the filling yarn is carried through the shed of warp yarns to the other side of the loom by finger-like carriers called rapiers. [1] A stationary package of yarn is used to supply the weft yarns in the rapier machine. One end of a rapier, a rod or steel tape, carries the weft yarn.
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 advantage of this type of weaving is that water power is cheaper where water is directly available on site. Picks per minute can reach as high as 1,000. Rapier loom: This type of weaving is very versatile, in that rapier looms can weave using a large variety of threads. There are several types of rapiers, but they all use a hook system ...
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 process here is similar to that found in one of Arkwrights Water frames, though the size of the ring, spindle and traveller are predictably larger. Alternatively a 'twiner' is used: this is a modified spinning mule and is mainly consigned to the doubling of warp thread. [ 10 ]
The improvement allowed a weaver to run two power looms instead of one. Its labor-saving feature appealed to Ira, and he decided to push its sale to weavers in the area. In 1829 he took out a patent for an improvement on his original invention. In 1830 he sold his patents and the business to his eldest son, James of Wayland, Massachusetts.
Toilet-tissue winders are able to change over at running speed, while paper and board winders need to stop the winding process in order to cut the sheet and glue the paper on to a new wind-up core. Top-line winders introduce the paper core through a maintenance pit downstairs, with web interruption time as low as 15 seconds.
