Abstract
An individually controlled needle tufting machine having loopers with beaks pointing in the same direction as the backing material being fed through the machine so as to form loop pile has means for laterally shifting the backing material continuously first in one direction and then in the other. The method is disclosed utilizing this apparatus for forming zig-zag backstitches with selective needles by stitching during each cycle of the machine, while in other selective needles linear backstitches are formed by driving those needles during alternate cycles. Fabrics are produced utilizing this method wherein the loop density produced can be selectively chosen for various portions of the fabric so as to provide patterning effects. By foregoing the shifting of the backing material similar, but less pronounced patterning effects may be attained.
