Abstract
A knife block for mounting four knives in staggered needle fine gauge tufting machines having a pair of dovetail shaped inserts slidably received within a pair of dovetail shaped cavities formed on opposite sides of a central web in a block body member. The inserts include a pair of rectangular grooves sized to receive tufting knives. One groove cooperates with the web to form a knife receiving channel and the other groove, which is laterally offset from the first grove by the machine stagger, is undercut from the outer face of the insert to provide another knife receiving channel. A clamping member locks both outer knives in the channels, and screw members lock each of the inner knives in the respective channels.
