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 ...
A weaving shed, showing how all the looms were powered from overhead shafts. The early mills had a vertical shaft to take the power from the flywheel. On each floor horizontal shafts engaged with the main shaft using bevel gearing. American mills used thick leather belts instead of shafts. A new approach was to use thick cotton ropes.
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.
A power loom is a mechanized loom, and was one of the key developments in the industrialization of weaving during the early Industrial Revolution. The first power loom was designed and patented in 1785 by Edmund Cartwright. [1] It was refined over the next 47 years until a design by the Howard and Bullough company made the operation completely ...
Double Diamond is the name of a design process model popularized by the British Design Council in 2005. [1] The process was adapted from the divergence-convergence model proposed in 1996 by Hungarian-American linguist Béla H. Bánáthy. [2] [3] The two diamonds represent a process of exploring an issue more widely or deeply (divergent thinking ...
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 ...
There is no need for layering to create a part, because a single fabric provides the full three-dimensional reinforcement. The 3-D woven fabric is a variant of the 2D weaving process, and it is an extension of the very old technique of creating double and triple woven cloth. 3D weaving allows the production of fabrics up to 10 cm in thickness.

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.
