A type of loom on which small, geometric figures can be woven as a regular pattern of the fabric. Originally this type of loom needed a “dobby boy” who sat on the top of the loom and drew up warp threads to form a pattern. Now the weaving is done entirely by machine. Dobby looms produce patterns which are beyond the range of simple looms, but are somewhat limited compared to a Jacquard loom, which has a wider range of pattern capabilities.
