Abstract
A yarn adjuster positioned adjacent tufting needles in a tufting machine for engaging yarn in close proximity to the tufting needles and moving it a predetermined distance to thereby control the length of the yarn on each side of the needles which controls evenness of tufts particularly when dual tufting needles are utilized to tuft U-shaped tufts. The yarn adjuster may be driven by an improved coupler point drive featuring long dwell and fast rise.
