What is "Dobby" - Definition & Explanation

A mechanism for controlling the vertical position of heald shafts on a loom, so as to selectively raise some warp threads while leaving others depressed. The use of a dobby facilitates the weaving of a fabric which has a more complex structure.
An attachment to a loom which controls the harness allowing the weaving of these geometric patterns.
Woven on a dobby loom, this fabric can be made with a dot or geometric design. A decorative weave, characterized by small figures, usually geometric, that are woven into the fabric structure. Dobbies may be of any weight or compactness, with yarns ranging from very fine to coarse and fluffy. Standard dobby fabrics are usually flat and relatively fine or sheer. However, some heavyweight dobby fabrics are available for home furnishings and for heavy apparel.
A fabric with small, repeating geometric patterns woven into the surface.
A general term for a fabric woven on a special dobby loom, which allows the weaving of small, geometric figures. These patterns are beyond the range of simple looms, yet too limited to be produced economically by Jacquard loom. A dobby weave can be distinguished from a plain weave by its more ornate and intricate woven appearance.
A mechanism attached to a loom for controlling the movement of the heald shafts.

NOTE:

It is required when the number of heald shafts or the number of picks in a repeat of a pattern, or both, are beyond the capacity of the tappet shedding.

Weave forming small repeat geometric patterns. Includes material with small figures such as dots, geometrical designs and floral patterns woven in the fabric.
A fabric made with a dobby, namely a loom with an attachment for weaving small figures
