CUT PILE TUFTING MACHINE CUTTING ELEMENTS

摘要

A tufting machine in which knives (24) are mounted in an untensioned condition. The necessary tension between the knives and cooperating hooks (18) is provided by a cam surface (42) on the shank of the hook, and also by a scissor angle of substantially 4 DEG formed by inclining the hook and the knife towards one another. Each hook (18) is tilted about a horizontal axis parallel to the direction in which backing medium is fed through the machine so as to offset the cutting edge of the hook and reduce J-cutting.
