In the drawings, the parts corresponding to the parts shown in FIGS. 2 and 3 are given the same numbers and the description thereof will be omitted.

As shown in FIG. 5, the needle 3 is arranged in the vertical direction, and the sinker 6 is arranged in the horizontal direction so as to be orthogonal to the needle 3. As described above, the needle 3 is driven up and down in the vertical direction. When the knitting yarn is to be poured into the ground knitting structure, the position for raising the needle 3 is adjusted to the top of the first height position L1 (see FIG. 4) as described above, but the first height is adjusted. The top of position L1 is adjusted within the range shown in FIG. That is, the region from the upper limit position, which is the ceiling position of the hook portion 32 of the needle 3, to the lower limit position, which is the tip position of the latch portion 33 in the open state of the needle 3, is called the latch motion region RM. At the timing when the height position corresponds to the clear level when knitting the ground knitting structure, the hook portion 32 of the needle 3 is the height position corresponding to the tack level and is the latch motion region RM. It is adjusted so that it is located in a region that is 20% lower than the upper limit and is 10% higher than the lower limit of the latch motion region RM.

By adjusting all the needles 3, 3, ... In the region corresponding to the third port of the cylinder 1 to a constant height position in the above-mentioned region, the knitting yarn is poured into the ground knitting structure. While it can be knitted so that there is no knitting, the knitting yarn engages with the ground knitting structure at random positions of the ground knitting structure, so that the knitting thread skips multiple random stitches on the ground knitting structure. Engage at random positions.

As shown in FIG. 1 or 4, the knitting structure M (see FIG. 1) knitted in this manner is blown with gas from the first nozzle 11 to skip a plurality of stitches of the knitting yarn. The part, that is, the area not engaged with the ground knitting structure, is removed from the ground knitting structure and extended to the outside of the ground knitting structure to form a free area. At this time, as shown in FIG. 4, the first nozzle 11 is arranged on the stitch cams 55 and 56, and the thread is held by the hook portion 32 of the needle 3 in which the latch portion 33 is closed. Since the gas is blown from the first nozzle 11 to the knitted structure, the gas blown from the first nozzle 11 has no effect on the knitted structure.

FIG. 6 is a schematic view showing an example of a structure knitted by the knitting method according to the present invention, in which G indicates a ground knitting structure and S indicates a knitting thread. Further, FIG. 7 is a schematic view showing an example of the structure after the gas is blown from the first nozzle 11 (see FIG. 1 or 4) onto the knitting structure M shown in FIG. In both figures, the corresponding parts are numbered the same.

As shown in FIG. 6, in the knitting structure M according to the present invention, a plurality of random eyes of the ground knitting structure G are skipped, and a plurality of engaging points SN, SN, ... Of the ground knitting structure G are engaged. It is matched.

When gas is blown from the first nozzle 11 to the knitting structure M as described above, as shown in FIG. 7, the region of the knitting thread S not entwined with the ground knitting structure G is separated from the ground knitting structure G. A plurality of long loop-shaped free regions SF, SF, ... Are randomly formed so as to extend to the outside of the ground knitting structure G.

Such free regions SF, SF, ... Are completely different from the conventional naps and brushes due to the randomness of their lengths and positions, and can sufficiently respond to the diversification of products.

In this embodiment, the long loop-shaped free regions SF, SF, ... Are shown, but the present invention is not limited to this, and the long loop is cut in the middle of the longitudinal direction to form a linear free region. It goes without saying that you can do it. Further, although the circular knitting machine has been described in this embodiment, the present invention is not limited to this, and can be applied to, for example, a flat knitting machine that performs weft knitting by reciprocating motion.
