A split-knitting method, on a flatbed knitting machine which is provided with at least a front and a rear needle bed being opposed to each other and an interposing needle bed gap, knitting needles, at a leading end of which a hook is provided to be opened and closed by a latch, arranged on each needle bed in parallel along a lengthwise direction in a state capable of causing the hooks to advance to and retreat from the needle bed gap, the method comprising: using a cam system (6, 36) being mounted on a carriage, running back and forth in a lengthwise direction of the needle beds, that includes a stitch cam (11, 12; 41, 42) which draws a knitting needle advanced to the needle bed gap into the needle bed and a stitch transfer cam (14, 15, 16, 17) which is used for a stitch transfer operation between a sending side and a receiving side, and enabling to select a knit or a split knit by needle selection in the same knitting course for knitting needles retaining old stitches on one needle bed: wherein, when the knit is selected, a new stitch is formed by knocking over a retained remaining part of the old stitch, and when the split knit is selected, a knitting needle for a sending side of the split knit newly forms a sending-side stitch by stitch-transferring a part of the old stitch and a remaining part of the old stitch being knocked over by the newly formed sending-side stitch, the method being characterized by further comprising: guiding both of a knitting needle which is selected for the kit and an other knitting needle which is selected for the sending side of the split knit on a same selection path on the one needle bed until a hook of each knitting needle is made to retreat from the needle bed gap after the hook has been made to advance to the needle bed gap: providing a presser (20, 21; 50, 51) to face a position at which the knitting needle receives an action by the stitch cam (11, 12; 41, 42) and to press the knitting needle on a selection path for the sending side of stitch transfer drawing the knitting needle, which is selected for the knit by the stitch cam (11, 12; 41, 42) using a needle selecting position at which the knitting needle receives no pressing by the presser (20, 21; 50, 51); and causing the knitting needle, which is selected for the sending side of the split knit by using a needle selecting position at which the knitting needle receives pressing by the presser (20, 21; 50, 51) and which is different from the needle selecting position for the knit, not to draw at all or to draw by a reduced drawing amount smaller than a drawing amount for the knit if drawing by the stitch cam (11, 12; 41, 42) is made. using a cam system (6, 36) being mounted on a carriage, running back and forth in a lengthwise direction of the needle beds, that includes a stitch cam (11, 12; 41, 42) which draws a knitting needle advanced to the needle bed gap into the needle bed and a stitch transfer cam (14, 15, 16, 17) which is used for a stitch transfer operation between a sending side and a receiving side, and enabling to select a knit or a split knit by needle selection in the same knitting course for knitting needles retaining old stitches on one needle bed: wherein, when the knit is selected, a new stitch is formed by knocking over a retained remaining part of the old stitch, and when the split knit is selected, a knitting needle for a sending side of the split knit newly forms a sending-side stitch by stitch-transferring a part of the old stitch and a remaining part of the old stitch being knocked over by the newly formed sending-side stitch, guiding both of a knitting needle which is selected for the kit and an other knitting needle which is selected for the sending side of the split knit on a same selection path on the one needle bed until a hook of each knitting needle is made to retreat from the needle bed gap after the hook has been made to advance to the needle bed gap: providing a presser (20, 21; 50, 51) to face a position at which the knitting needle receives an action by the stitch cam (11, 12; 41, 42) and to press the knitting needle on a selection path for the sending side of stitch transfer drawing the knitting needle, which is selected for the knit by the stitch cam (11, 12; 41, 42) using a needle selecting position at which the knitting needle receives no pressing by the presser (20, 21; 50, 51); and causing the knitting needle, which is selected for the sending side of the split knit by using a needle selecting position at which the knitting needle receives pressing by the presser (20, 21; 50, 51) and which is different from the needle selecting position for the knit, not to draw at all or to draw by a reduced drawing amount smaller than a drawing amount for the knit if drawing by the stitch cam (11, 12; 41, 42) is made. providing a presser (20, 21; 50, 51) to face a position at which the knitting needle receives an action by the stitch cam (11, 12; 41, 42) and to press the knitting needle on a selection path for the sending side of stitch transfer drawing the knitting needle, which is selected for the knit by the stitch cam (11, 12; 41, 42) using a needle selecting position at which the knitting needle receives no pressing by the presser (20, 21; 50, 51); and causing the knitting needle, which is selected for the sending side of the split knit by using a needle selecting position at which the knitting needle receives pressing by the presser (20, 21; 50, 51) and which is different from the needle selecting position for the knit, not to draw at all or to draw by a reduced drawing amount smaller than a drawing amount for the knit if drawing by the stitch cam (11, 12; 41, 42) is made.
