Abstract
A loop cutting apparatus for a cut pile tufting machine including looper hooks, for cooperating with corresponding reciprocal needles, mounted in a hook bar supported on a looper rocker arm for pivotal movement about a hook shaft, the knives cooperating with the looper hooks being fixed in a knife bar supported on a lever member mounted for pivotal movement on the looper rocker arm, and a drive mechanism operatively connected to the looper rocker arm and the lever member for reciprocally moving the rocker arm and lever member simultaneously in opposite directions for cooperative movement of the knives and hooks to form cut pile. The loop cutting apparatus is further characterized by locating the pivotal axis of the lever member at an elevated position upon the looper rocker arm so that the movement of the knives relative to the looper hooks is substantially vertical, thereby requiring less reciprocal movement of the hooks and knives for effectively cutting the loops seized by the hooks.
