Abstract

A warp knit net fabric is disclosed in which the number of stitches in each leg and in each join of a diamond pattern is varied to vary the size of the openings defined by the legs. An array of yarn ends are knit on a Raschel warp knitting machine and the formation of stitches of the legs is driven from one pattern chain drum and the formation of stitches of the joins is driven from another pattern chain drum. Switching from drum to drum is accomplished by a programmable controller.
