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.

A warp-weighted loom (see diagram) typically uses a heddle-bar, or several. It has two upright posts (C); they support a horizontal beam (D), which is cylindrical so that the finished cloth can be rolled around it, allowing the loom to be used to weave a piece of cloth taller than the loom, and preserving an ergonomic working height.
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 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 ...
[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]
Doubling of yarn where two or more stands or ends of yarn are twisted together. There are many purposes where doubled yarn is used. Sometimes thread is doubled to make warp, and it is invariably used for the manufacture of knitting yarn, crochet yarn and sewing yarn. All these yarns must be smooth and free from knots.
The shed-rod was an invention of eastern origin, and was introduced to Europe via Egypt in the first century AD. The Romans used it for both plain weave and twill. [4] After the shed-rod came the rigid heddle loom, where the shed is created by raising or lowering the rigid heddle. As the loom progressed, the shed-rod was replaced by a second ...
