ABSTRACT A method and apparatus for knitting intarsia design jersey knit fabric on a circular knitting, machine capable of knitting single jersey fabric. The method includes the steps of raising groups of contiguous needles on the needle cylinder, drawing down, one after the other in a first direction, the raised needles to form a new stitch loop in the hook of each needle as it is drawn down and to shed the old stitch loop into the jersey fabric being knitted, while drawing down the needles of the first group of needles in the first direction, raising the needles of the next group of needles and drawing down, one after the other the needles of such next group after all of the needles of the first group are drawn down until all of the needles are drawn down, new stitch loops are formed and the old stitch loops are shed, continuing, the movement in the first direction until the needles are cleared and then reversing the direction of movement, the raising of the needle groups, the drawing down and the clearing of the needles, cycle after cycle, until the knitting is completed. The apparatus includes pushers for raising the needles, a knitting cam for drawing the raised needles, one after the other, down, yarn feeds for feeding yarn to the raised needles, pusher cam means for raising and lowering the pushers, means for reciprocating the knitting cam means, back and forth, around the cylinder to draw the needles down after they are raised by the pushers and means for reversing the direction of reciprocation of the knitting cam after the raised needles of a first and a next group of needles have been raised and drawn down and the knitting cam has cleared such needles.
