In order to make the amount of offset with 5 zero, the position of the mounting table 38 was moved from the y dimension in FIG. 3 to the z dimension in FIG. 4, and the knitting needles were opposed to each other. After the knitting needles 2 and 15 are thus arranged facing each other, the fixing plate 24 provided at the lower end of the sub-needle bed 14 is fixed to the knitting stand 3 with the mounting bracket 25 (FIG. 1), and the installation is completed.

[Effect of idea]

As described above, the present invention provides a rubber knitting machine in which mounting plates are provided at both ends of the sub-needle bed, and the mounting plates are attached to the front part of the main needle bed fixed to the knitting stand. A support base fixed to the front part, a moving shaft rotatably held by the support base, a mounting base screwed onto the moving shaft and carrying a mounting plate, and elastically pressing the moving shaft to move the movement. Since the subneedle bed adjusting device is provided with a fixing means for preventing rotation of the shaft, the following effects are achieved.

By appropriately rotating the moving shaft, the sub needle bed can be set in the correct position relative to the main needle bed.

Since the fixing means elastically presses and fixes the moving shaft, it does not loosen due to vibrations during knitting, and therefore, the set position can be correctly secured without moving the mounting table.
