Lappet-Weaving. A system of weaving used for producing figures on the surface of cloth by means of needles placed in a sliding frame, called the lappet-frame, which has a sliding bar carrying needles, each with a separate thread for producing certain colors in the pattern. The bar is raised and lowered as required by the action of a wheel grooved according to the pattern to be produced. Sometimes two or more such bars are employed simultaneously when several colors are made to appear in weft-patterns.
