  Conventionally, as shown in FIG. 13, a warp knitting machine is provided with guide elements 4 having guide holes 2 for guiding a knitting yarn at the tip thereof at a fixed interval, and the guide bar 6 is a rod. The chain 10 is connected to a chain 10 having a predetermined height. The guide bar 6 is provided over the width of the knitted fabric, and a chain 10 that is a drive device for the guide bar 6 is located on one side of the guide bar 6. The chain 10 is formed on the outer periphery of the chain drum 12, and the chain drum 12 is rotated in synchronization with a predetermined knitting cycle by a motor (not shown). Furthermore, the guide bar 6 is always pulled toward the chain 10 via the wire 16 by the coil spring 14.

  In the case of the above-described conventional technology, in order to form a knitted fabric having partially different stretchability on a fabric knitted by an existing warp knitting machine, the method of adjusting the movement of the guide bar that is the ground has its movable range. However, it was about 15 mm at most, and only a relatively fine linear change was obtained. In addition, there is a pattern guide bar that partially increases the yarn density to change the stretchability, but it is difficult to knit the yarn at a high density. Furthermore, even if the yarn density is forcibly increased, the hitting of the guide occurs, and a large number of sheets are required, resulting in poor productivity.

  It is also possible to partially change the stretchability of the knitted fabric using the jacquard device, but since the jacquard yarn exists over the entire width of the fabric, it is difficult to arbitrarily change the stretchability. It was.
