Abstract
A knife holder apparatus for a cut pile tufting machine including a plurality of knife blocks, each knife block being fixed to a depending staff having an upright elongated channel, and a transverse knife bar having forwardly projecting, transversely spaced angular rib members for receiving the channels of the corresponding staffs. A transverse clamp pin bridging the channel of each staff is adapted to be received in a transverse clamping slot formed at a rearward inclination in each rib member and to be forced upward against the rearwardly inclined upper wall of the transverse slot by a set screw projecting upwardly into the slot for clamping the knife block in a predetermined position upon the knife bar to hold the knives in their tensioned positions against their corresponding looper hooks.
