Abstract
A tufting machine including spaced rows of needles for inserting yarns into a backing material. The needles are engaged by a series of cut pile hooks and level cut loop loopers or hooks that generally are arranged at spaced elevations. The cut pile hooks will engage one of the rows of needles for forming cut pile tufts of yarns in the backing material. The level cut loop loopers or hooks engage the other row of needles and each include clips. The clips are selectively moved into a position substantially blocking retention of loops of yarns picked up and/or formed along their level cut loop loopers or hooks for formation of loop and cut pile tufts of yarns in the backing material.
