Binding-off process, bound off fabric, and CAD system for binding-off process

A CAD system used for a binding-off process which is performed by using a flat knitting machine comprising at least a pair of first and second needle beds, which have a number of needles, respectively, and are placed opposite in front and back;

• between which a needle bed gap is defined;
• and at least either of which is movable slidably transversely, and at least one yarn feeder for feeding a yarn to the needles of the first needle bed and the second needle bed, and in which the knitting that a bind-off loop formed continuously with a loop in the last course of a tubular fabric comprising first and second knitted fabrics is laid over a loop adjoining to the bind-off loop formed continuously with the loop in the last course of the fabric, to form a bind-off loop of the next course is repeated from one end of a region of the binding-off process toward the other end, to join the first and second knitted fabrics to each other on the side on which the knitting is finished, the CAD system being designed to give knitting commands for:
• 1) the process of at least three bind-off courses being formed starting at not less than three loops, including loops of the first and second knitted fabrics at side ends thereof in the region of the binding-off process and a loop adjoining to the loop of at least either of the first and second knitted fabrics at the side end, and
• 2) the process that the loop of the bind-off course formed is laid over the loop of the last course of the opposite knitted fabric in such a manner that while being formed, the respective bind-off courses can be allowed to extend in a zigzag pattern from the first knitted fabric to the second knitted fabric and vice versa, ranging over the region of the binding-off process, to be crossed with each other.
