ABSTRACT:
The needle latch cushioning member is formed of resilient material and includes an elongate body portion with a free end portion. The elongate body portion is supported in a groove on a yarn feed finger so that the free end portion is positioned to be engaged by and interrupt the swinging movement of the latches of the needles to the closed position as the needles are lowered to stitch loop forming position. The engagement of the latches of the needles with the free end portion of the resilient cushioning member serves to reduce the impact force of the latches against the hooks of the needles and thereby increases the wear life of the needles, without interfering with the feeding of the yarn into the hooks of the needles. When properly positioned, the free end of the resilient cushioning member can be used to guide the yarn into the hooks of the needles.
