Certain groups of adjacent warp yarns are at times fed to the circular warp knitting machine at a different rate than the remaining groups of warp yarns to thereby vary the length of the stitch loops being formed and to fashion the tubular fabric while it is being knit. Pairs of warp yarn feeding rolls are drivingly interconnected and are arranged around the needle cylinder. One pair of rolls may be selectively driven at a different speed, relative to the other rolls to at times feed a selected group of warp yarns at a different rate and to at times feed all the warp yarns at the same rate.
