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.

Claims

1. A tufted fabric comprising a backing having longitudinal rows of tufts of first yarns and longitudinal rows of tufts of second yarns interspersed between said longitudinal rows of tufts of first yarns, the rows of tufts of first yarns having successive cut pile tufts and being zig-zagged along its length so that the tufts of the zig-zagged rows of yarns are displaced laterally across adjacent rows of other yarns and the respective rows of tufts of second yarns having both cut pile and loop pile tufts, the cut pile tufts and loop tufts being of the same height.

2. A tufted fabric comprising of backing having longitudinal rows of tufts of first yarns and longitudinal rows of tufts of second yarns in a space between said longitudinal rows of tufts of first yarns, the rows of tufts of first yarns having successive cut pile tufts and loop pile tufts and being zig-zagged across its length so that the tufts of the zig-zagged rows of yarns are displayed laterally across adjacent rows of other yarns, the respective rows of tufts of second yarns having cut pile tufts which are of substantially the same height as the cut pile tufts of the rows of first yarns and of substantially the height as the rows of loop pile tufts therein.
