METHOD OF COMPENSATING FOR CHARGE LOSS DURING KNITTING OF SLIVER MULTI-COLOR PATTERNED HIGH PILE FABRIC Abstract Method for maintaining constant the fiber charge in a sliver feeding system during the knitting of multi-color patterned sliver high pile fabrics on multi-feed circular knitting machines. In knitting multi-color patterned high pile fabrics, each sliver is advanced at feeding rates pro- portionate to the number of needles selected, the speed of rotation of the needle circle, the selected density of the pile fabric being knit and the approximate rate of fly loss, to maintainthe charge of fibers in each sliver feeding system at a constant level at all times. Sliver feed rolls of each sliver feeding mechanism or card are rotated continuously, to advance each sliver continuously to the main cylinder and doffer at not less than selected minimum rates of feed sufficient to compensate for any depletion of the charge. This ensures the provision on each doffer of sufficient quan- tities of sliver fiber to meet the demand of needles for fiber while compensating for charge loss resulting from fly loss and either the non-selection of needles or the selection of so few needles that the needle demand for fibers, and hence the rate of sliver feed, falls below the rate of fly loss.
