An encyclopedia article on diaper, a twill-based cloth used chiefly for table linen, and on the loom mounting used to weave it. It explains how diaper uses broken five-leaf twill with reversed floats to form figures, and how a back harness operated by the weaver's hand supplements the front treadle mounting. It describes the parts of the diaper loom shown in an engraved figure (breast beam, cloth beam, treadles, back harness, cords and pulleys, and the iron or copper eyes called mails).
