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.

[1]Double cloth or double weave (also doublecloth, double-cloth, doubleweave) is a kind of woven textile in which two or more sets of warps and one or more sets of weft or filling yarns are interconnected to form a two-layered cloth.

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 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 schematic diagram of the Jacquard system 19th century Engineering drawing of a Jacquard loom. As shown in the diagram, the cards are fastened into a continuous chain (1) which passes over a square box. At each quarter rotation, a new card is presented to the Jacquard head which represents one row (one "pick" of the shuttle carrying the weft ...
The warp is threaded through heddles on different shafts in order to obtain different weave structures. 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.
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.
