Abstract: The present yarn guide tubes are fixed on one face of profile plates which are in turn carried on a support bar operated from the carrier rods of the knitting machine. The centers of the yarn guide tubes are spaced the same distance as the spacing of the needles and the free ends are sufficiently spaced apart to at times to permit the needles to pass therebetween. Selective positions on the support bar, or the entire support bar, may be provided with the profile plates and inlay yarns are fed through the selected tubes where it is desired to produce zig-zag striping, diamonds and various other motifs in the knit fabric.

Abstract: This reverse racking mechanism is particularly adapted for use with warp knitting machines of the type including inlay yarn guide tubes supported on carrier rods with each of the carrier rods being racked or shogged by a separate pattern chain to form various types of zig-zag patterns on the knit fabric. As step-by-step racking movement is imparted to a particular carrier rod, the present mechanism imparts the same racking movement in a reverse direction to an adjacent carrier rod. The present mechanism includes rack means carried by the adjacent carrier rods with a pinion supported between and in engagement with the two racks so that any racking movement imparted to one carrier rod is imparted to the adjacent carrier rod but in a reverse direction.

Abstract: This racking control is particularly adapted for warp knitting machines of the type including weft inlay yarn feed tubes to which a limited range of step-by-step racking movements may be imparted to produce zig-zag striping, diamonds and various other motifs in the knit fabric. The present racking control is utilized to substantially increase the normally limited racking movement to thereby increase the size of such motifs which may be formed in the knit fabric. The normal amount of limited racking movement is imparted by a main pattern chain acting on a main carrier rod and an auxiliary carrier rod is selectively latched to the main carrier rod for providing additional racking movement by means of an auxiliary pattern chain.
