The Parts of a Rug Loom

Most weavers work on fixed, vertical looms (although some semi-nomadic weavers in areas of Afghanistan, Turkey, and Iran still use the more portable horizontal ground loom). A simple vertical loom is little more than a sturdy frame, usually made of wooden timbers, designed to hold taut the warp strings upon which the weaver ties rows of knots. A heddle is used to separate alternate warps so that the shuttle carrying the weft string can be passed between warps from one side of the rug to the other. More sophisticated vertical looms have their upper and lower beams constructed as rollers. A roller loom lets the weaver roll the completed part of a rug under and to the back of the loom, allowing the construction of a longer carpet on a loom of the same vertical size.
