A loom from the 1890s with a dobby head. A dobby loom, or dobbie loom, [1] is a type of floor loom that controls all the warp threads using a device called a dobby. [2]Dobbies can produce more complex fabric designs than tappet looms [2] but are limited in comparison to Jacquard looms.
Note that it may still be copyrighted in jurisdictions that do not apply the rule of the shorter term for US works (depending on the date of the author's death), such as Canada (70 years p.m.a.), Mainland China (50 years p.m.a., not Hong Kong or Macao), Germany (70 years p.m.a.), Mexico (100 years p.m.a.), Switzerland (70 years p.m.a.), and other countries with individual treaties.
A Barber-Colman knotter is a piece of textile machinery used in a weaving shed. When all the warp carried on the weavers beam has been used, a new beam replaces it. Each end has to pass through the eyes on the existing heddles, and through the existing reed. The knotter takes each new thread and knots it the existing end, which will pull it ...
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 ...
In 1785 Edmund Cartwright patented a power loom which used water power to speed up the weaving process, the predecessor to the modern power loom. His ideas were licensed first by Grimshaw of Manchester who built a small steam-powered weaving factory in Manchester in 1790, but the factory burnt down. Cartwright's was not a commercially ...
[4] To use a temple, the length is first adjusted so that it matches the total width (or spread) of warp threads in the reed. The prongs are then inserted into the fabric, on each side, at the very edges of the cloth. The temple must be moved frequently to keep it close to the fell of the fabric, where the weaving is taking place. [2]
The double rapier is used more frequently than the single rapier due to its increased pick insertion speed and ability to weave wider widths of fabric. The housing for the rapiers must take up as much space as the width of the machine. To overcome this problem, looms with flexible rapiers have been devised. The flexible rapier can be coiled as ...
Holding the reed beater bar in the left hand, and the (picking-stick-mounted) string tugged to return the flying shuttle in the right hand.See video below. In a typical frame loom, as used previous to the invention of the flying shuttle, the operator sat with the newly woven cloth before them, using treadles or some other mechanism to raise and lower the heddles, which opened the shed in the ...
