Abstract:

A weaving board includes a flat base, a first pair of longitudinally spaced apart ridges projecting from one side of the base, and a second pair of ridges projecting from an opposite side of the base. The ridges on each side of the base are located relatively near the opposite ends of the base, and each ridge is continuous for the width of the base. Separate series of grooves are formed in opposite ends of the base. The grooves are preferably wider than the spacing between them; and preferably, the projections formed between the grooves are rounded at their remote ends. The grooves segregate separate rows of warp yarns extending lengthwise around the board and over the ridges. The ridges space the warp yarns from the opposite sides of the board to provide room for weaving consecutive rows of woof of weft yarns through the warp yarns.
