ABSTRACT:
A knife assembly for a fine gauge tufting machine comprises a rectangular clamping bar and a series of knife blocks mounted side by side on the knife bar. Each knife block carries a number of knives mounted in parallel grooves in the knife block machined in a direction to present the knives to loopers of the machine at the desired cutting angle. The knives are retained in each knife block by a plate and clamping screws which extend through the plate to engage the edges of the knives. Each knife block has a rearwardly extending peg which is clamped in a hole in the knife bar with the knife block orientated to present the knives to the loopers at the desired pressing angle.
