There are provided a linking method and a linking apparatus capable of solidly linking a knitting fabric by automatically carrying out operation of piercing a point needle through an overlocking loop knitted at the knitting fabric swiftly and accurately. A linking method according to the invention is a linking method having a step of expanding a knitting fabric in a state of opposing linking object portions, a step of picking up an image of the expanded knitting fabric, a step of detecting a position of an overlocking loop from the picked-up image, a step of positioning the point needle corresponding to the detected position of the overlooking loop thereto, a step of piercing the corresponding point needle through the detected overlooking loop and a step of overlocking the knitting fabric based on the point needle pierced through each of the overlocking loops of the knitting fabric, in which tacking needles are pierced through the overlocking loops at both end portions of the knitting fabric before the step of expanding the knitting fabric and the tacking needles are coupled with the point needles corresponding to the overlocking loops at the both end portions of the knitting fabric after the step of expanding the knitting fabric.

There are provided a process and an apparatus for detecting loop stitches of a tubular knitted fabric and an apparatus for linking the tubular knitted fabric, which can automatically detect each of loop stitches formed in the tubular knitted fabric. According to the process for detecting the loop stitches, the tubular knitted fabric is extended by inserting a penetration element through the interior of the fabric having the loop stitches, and a multi-gradation image including an image of the loop stitches of the tubular knitted fabric extended by the penetration element is picked up. The locations of the loop stitches are detected by processing the multi-gradation image.

There are provided a linking method and a linking apparatus capable of automatically carrying out operation of piercing a point needle to an overlocking loop knitted at a knitting fabric swiftly and accurately to thereby solidly link the knitting fabric. By using a main body mechanism (100) having an inserting member (110) for being inserted through a sock to expand, a needle piercing mechanism (120), a CCD camera (140) and a computer (150), detecting initial overlocking loops simultaneously on a front side and a rear side (S108), thereafter detecting a position of the overlocking loop (S112), positioning the point needle (S114) and piercing the point needle (S116) are repeated, when the point needles have finished piercing to all of the overlocking loops, the point needles are returned to initial positions (S120). When the operation has been finished with both faces of the knitting fabric, the inserting member (110) is drawn (S122), the sock W is moved to one of the point needles (S124) and overlocked (S126). Further, a semiautomatic processing by a tacking needle or an automatic processing using an inserting member having converged both ends can also be carried out.

A method for linking plain knitted fabrics includes the steps of fixing a first plain knitted fabric in a stretched state, obtaining an image including an image of a darning stitch of the first plain knitted fabric in the stretched state, calculating a location of the darning stitch of the first plain knitted fabric from the obtained image, holding a second plain knitted fabric in a stretched state, obtaining an image including an image of a darning stitch of the second plain knitted fabric in the stretched state, calculating a location of the darning stitch of the second plain knitted fabric from the obtained image, moving the first plain knitted fabric and the second plain knitted fabric relative to each other to align the darning stitch of the second plain knitted fabric with the darning stitch of the first plain knitted fabric, moving a sewing machine needle of a sewing machine mechanism to the location of the darning stitch of the first plain knitted fabric, and linking together the darning stitch of the first plain knitted fabric and the darning stitch of the second plain knitted fabric with the sewing machine needle.

A process and an apparatus for detecting loop stitches of a tubular knitted fabric and an apparatus (1) for linking the tubular knitted fabric, which can automatically detect each of loop stitches formed in the tubular knitted fabric. According to the process for detecting the loop stitches, the tubular knitted fabric is extended by inserting a penetration element (12a,12b) through the interior of the fabric having the loop stitches, and a multi-gradation image including an image of the loop stitches of the tubular knitted fabric extended by the penetration element is picked up. The locations of the loop stitches are detected by processing the multi-gradation image.
