A dobby is a shedding mechanism attached to a loom that controls the movement of the harnesses, allowing for more complex weave structures than a basic cam loom but fewer than a Jacquard machine. It typically handles up to 24 or 36 harnesses. The device uses a chain of pegged wooden bars or a computerized interface to lift specific warp threads, producing textured fabrics with small woven motifs like pique, waffle cloth, or miniature diamonds.
The dobby chain needs to be re-pegged before we can start the next run of that diamond twill shirting.
