A method for knitting interchanged plating on a single face of technical face for a flat bed knitting machine which includes at least one needle bed that comprises a plurality of latch needles and a plurality of sinkers hinged on an upper end of the needle bed abutting respectively each latch needle , and a carriage movable reciprocally and linearly above the needle bed , characterized in that the method comprises the steps of: providing an indented indentation at a front end of each sinker that is movable interactively with each latch needle and a nose protrusion abutting the indentation ; controlling the carriage to move reciprocally and linearly above the needle bed so that the latch needle is moved in a staged stitching displacement which includes a pause stitching operation; the staged stitching displacement including at least a first stitching section , a second stitching section and a delayed stitching section between the first stitching section and the second stitching section to generate the pause stitching operation; feeding a first coloration yarn and a second coloration yarn above the first coloration yarn at the same time to the flat bed knitting machine ; moving the first coloration yarn and the second coloration yarn via a front edge of the nose protrusion to slide down at the same time for knitting while the latch needle is positioned at the second stitching section to form a standard plating in which the first coloration yarn is below the second color yarn , and continuing the knitting operation through the standard plating to form a single face fabric; and controlling the carriage to make the latch needle perform an interchanged stitching displacement when the single face fabric knitted via the standard plating has reached a predetermined position, and ordering the sinker while the latch needle is located in the interchanged stitching displacement to pick up the first coloration yarn above the second coloration yarn via a junction of a rear edge of the nose protrusion and the indentation , then releasing the yarns to form an interchanged plating in which the second coloration yarn is below the first coloration yarn . providing an indented indentation at a front end of each sinker that is movable interactively with each latch needle and a nose protrusion abutting the indentation ; controlling the carriage to move reciprocally and linearly above the needle bed so that the latch needle is moved in a staged stitching displacement which includes a pause stitching operation; the staged stitching displacement including at least a first stitching section , a second stitching section and a delayed stitching section between the first stitching section and the second stitching section to generate the pause stitching operation; feeding a first coloration yarn and a second coloration yarn above the first coloration yarn at the same time to the flat bed knitting machine ; moving the first coloration yarn and the second coloration yarn via a front edge of the nose protrusion to slide down at the same time for knitting while the latch needle is positioned at the second stitching section to form a standard plating in which the first coloration yarn is below the second color yarn , and continuing the knitting operation through the standard plating to form a single face fabric; and controlling the carriage to make the latch needle perform an interchanged stitching displacement when the single face fabric knitted via the standard plating has reached a predetermined position, and ordering the sinker while the latch needle is located in the interchanged stitching displacement to pick up the first coloration yarn above the second coloration yarn via a junction of a rear edge of the nose protrusion and the indentation , then releasing the yarns to form an interchanged plating in which the second coloration yarn is below the first coloration yarn . <EOS>
