6. The method according to claim 1, wherein when the stitch of the front needle plate is equal to the stitch of the rear needle plate, the stitch formed on the knitting needle of the front needle plate is transferred to the empty needle of the rear needle plate.
7. The method according to claim 6, comprising the steps of:
step one: after the front needle plate moves rightwards, the left side of the knitting needle of the rear needle plate is aligned with the right side of the first knitting expansion piece of the front needle plate;
step two: the knitting needle of the front needle plate moves upwards to enable the coil to move to the position of the first ring expanding piece of the knitting needle;
step three: then, the knitting needle of the rear needle plate moves upwards to the lower right side of the knitting needle of the front needle plate, and then the rear needle plate moves leftwards to enter the first ring expanding piece of the knitting needle of the front needle plate, and the knitting needle of the rear needle plate hooks the yarn at the lower right side of the coil;
step four: and finally, along with the movement of the plate head, the knitting needles of the front needle plate are downwards moved, and the loops are transferred to the knitting needles of the rear needle plate.
8. The method according to claim 2, comprising the steps of:
step one: the front needle plate moves leftwards to align the right side of the knitting needle of the front needle plate with the left side of the first ring expanding piece of the knitting needle of the rear needle plate;
step two: the knitting needle of the rear needle plate moves upwards to enable the coil to move to the position of the first ring expanding piece of the knitting needle;
step three: then, the knitting needle of the front needle plate moves upwards to the lower left side of the first ring expansion piece of the knitting needle of the rear needle plate, then the front needle plate moves rightwards into the first ring expansion piece of the knitting needle of the rear needle plate, and the knitting needle of the front needle plate hooks the left lower side yarn of the coil;
step four: and finally, along with the movement of the plate head, the knitting needles of the rear needle plate are downwards moved, and the loops are transferred to the knitting needles of the front needle plate.
9. The method according to claim 2, comprising the steps of:
step one: the rear needle plate moves leftwards to align the right side of knitting of the rear needle plate with the left side of the second ring-expanding piece of the knitting needle of the front needle plate;
step two: the knitting needle of the front needle plate moves upwards to enable the coil to move to the position of the second ring expanding piece of the knitting needle;
step three: then, the rear needle plate moves upwards to the lower left side of the second ring-expanding piece of the knitting needle of the rear needle plate, then the rear needle plate moves rightwards, the knitting needle of the rear needle plate enters the second ring-expanding piece of the knitting needle of the front needle plate, and the knitting needle of the rear needle plate hooks the left lower side yarn of the coil;
step four: and finally, along with the movement of the plate head, the knitting needles of the front needle plate are downwards moved, and the loops are transferred to the knitting needles of the rear needle plate.
