ABSTRACT:
This is a knitting machine latch needle. The latch pivot is formed by displacing portions of the walls of the slot so that the displaced portions extend into the pivot hole of the latch. The displaced portions of the walls are fused together by a high energy heat source emitting sufficient energy to either drill a hole through the displaced portions or melt the displaced portions.
