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.
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 ...
For a plain weave on a loom with two shafts, for example, the first thread would go through the first heddle on the first shaft, and then the next thread through the first heddle on the second shaft. The third warp thread would be threaded through the second heddle on the first shaft, and so on.
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 ...
In the terminology of weaving, each warp thread is called a warp end; a pick is a single weft thread that crosses the warp thread (synonymous terms are fill yarn and filling yarn). [ 2 ] [ 3 ] In the 18th century, the Industrial Revolution facilitated the industrialisation of the production of textile fabrics with the "picking stick" [ 4 ] and ...
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 ...
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 ...
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.
