Abstract
A linking method including the steps of opposing knitted fabrics to be linked to each other, stretching the opposed knitted fabrics in a course direction, stretching the opposed knitted fabrics in a wale direction, picking up an image of linking loops of each of the stretched knitted fabrics, detecting the positions of the linking loops based on a multiple gray-scale image, inserting a point needle through each of the linking loops, sewing a linking loop in the vicinity of an edge of each of the knitted fabrics, and linking together the linking loops other than the sewn linking loop by using the point needle; and an apparatus for linking knitted fabrics.
Claims20
A method for linking knitted fabrics, each having a loose course for linking, comprising the steps of:
- opposing the knitted fabrics to be linked to each other;
- stretching the opposed knitted fabrics in a course direction;
- stretching the opposed knitted fabrics in a wale direction;
- picking up a multiple gray-scale image including an image of linking loops defining a loose course of each of the stretched knitted fabrics;
- performing an image processing on the multiple gray-scale image so as to detect positions of the linking loops;
- inserting a point needle through each of the linking loops;
- sewing a linking loop in a vicinity of an edge of each of the knitted fabrics;
- and
- threading the linking loops other than the sewn linking loop by using the point needle inserted through the linking loop so as to link the knitted fabrics together.
A linking apparatus for linking knitted fabrics, each having a loose course for linking, comprising:
- a course stretching device for stretching the knitted fabrics in a course direction in a state where the knitted fabrics are opposed to each other;
- a wale stretching device for stretching the opposed knitted fabrics in a wale direction;
- an image-pickup device for picking up a multiple grayscale image including an image of linking loops defining a loose course of each of the stretched knitted fabrics;
- a linking loop detector for performing an image processing on the multiple gray-scale image so as to detect positions of linking loops;
- a point needle insertion device for inserting a point needle through each of the linking loops;
- and
- a sewing machine mechanism for sewing a linking loop in a vicinity of an edge of each of the knitted fabrics and for threading the linking loops other than the sewn linking loop by using the point needle inserted through the linking loops to link the linking loops together.
