ABSTRACT:
A knife block for mounting at least three cutting knives in fine gauge cut pile tufting machines. The knife block has a pair of longitudinally extending spaced flanges connected together by a pair of laterally spaced apart web portions spaced longitudinally from each other. At least one knife is adapted to be received between the flanges intermediate the webs, and at least one knife is adapted to be received between the flanges laterally outwardly of each web. A method of making the knife block is also disclosed as including the steps of cutting at least one pair of knife receiving grooves in the flanges in the lateral space between the webs by feeding a rotating cutting blade from one extremity of the block substantially to the inner edge of one web and then turning the block and feeding the cutter from the other extremity to form at least one continuous knife receiving groove extending the full longitudinal width of the flanges.
