Abstract
Laterally shiftable front and back needle bars are slideably mounted on a main needle bar, the front needle bar carries a front row of needles and a back needle bar carries a back row of needles. Cut pile loopers cooperate with the needles of the back row and cut-loop loopers cooperate with the needles of the front row. Needles in the front row are larger and handle larger size yarns than needles in the back row and a yarn feed control dictates whether yarns in the front needles make low loops or high cut piles.
