File:Bardko.svg|Two types of rigid heddle|alt=Two rectangular heddles; widthwise slots don't quite reach either long edge, and a row of small circular holes lies between the slots, along the lengthwise midline. One heddle is carved of solid wood, the other has metal strips, each with a hole in the center and the ends slotted into two lengthwise wooden bars.

narrow work band; replica of the European Dark Ages. In rigid heddle looms there is typically a single shaft, with the heddles fixed in place in the shaft. The warp threads pass alternately through a heddle and through a space between the heddles, so that raising the shaft will raise half the threads (those passing through the heddles), and lowering the shaft will lower the same threads—the threads passing through the spaces between the heddles remain in place. Rigid heddles are thus very different from the heddle in common use, though the single heddle derived from the rigid heddle. The advantage of non-rigid heddles is that the weaver has more freedom, and can create a wider variety of fabrics. Rigid heddle looms resemble the standard floor loom in appearance.
Single and double heddle looms File:Haslach an der Mühl - Textiles Zentrum Haslach - 20 - Bandwebstuhl mit Loch-Schlitz-Blatt.jpg| An inkle loom with a single rigid heddle, moved by treadles and a pulley; a second heddle could easily be added. Single and double heddle looms are types of rigid heddle loom, in that the heddles are all together. Heddles are normally suspended above the loom. The weaver operates them by pedals and works while seated. Among hand woven
African textiles, single-heddle looms are in wide use among weaving regions of Africa. Mounting position varies according to local custom. Double-heddle looms are used in West Africa,
Ethiopia and in
Madagascar for the production of
lamba cloth. ==See also==
