The present invention is a circular knitting machine, in particular, a dubnit circular knitting machine, in which the mounting positions of some parts of the knitting recesses are made common in accordance with the change in the nominal dimension (needle cylinder diameter), thereby changing the number of replacement parts when changing the various nominal dimensions. The present invention relates to a circular knitting machine which can reduce the number of dimensions with one circular knitting machine at the same time.

Previously, each feeder is provided with securing means for securing a control unit for operating a knitting tool (knitting needle).

Each of these yarns was arranged on a plurality of divided segments and constituted an annular body.

The number of yarn feeders of the circular knitting machine is reduced by a nominal dimension, and the mounting position thereof is also provided at a position different by the nominal dimension. This is because the spaces occupied by the first-order sand ball, that is, the increase and decrease of each feeding yarn are adjusted by dividing based on the arc length of the arc portion of the Korean circular arc part, and the sudden feeding sphere of the nominal size is determined.

Accordingly, the number of divisions of each segment is also determined for various different nominal dimensions.

For example, in case of 41 circular knitting machines with a nominal dimension of 20 inches, the circumference of the ring body is divided into 41 equal parts.

This divides into 10 segments and the remaining first class feeder [41- (4x10) = 1] is excreted in another segment of size 1/4 of the above-mentioned one segment. In addition, the nominal dimensions are 19 inches, and the yarns with 39 yarns are divided into 9 segments, and the remaining 3 yarns [39- (4 × 9) -3] are 3/4 of the size of 1 segment. Exposed to other segments. In this way, each feed yarn is divided equally into each segment so that the remaining feed yarns are excreted in segments of different sizes.

On the other hand, since the cap ring on which the segment is mounted is provided for each title dimension, the cam ring of each title dimension and the mounting position of the segment also differ.

In the circular knitting machine, even if the same model is used, machines having different nominal dimensions are manufactured one by one, and among these, a knitter selects and holds a knitting machine of the nominal size, which is the demand of the final product. Moreover, production adjustment is performed by stopping or storing a machine according to the production plan of a letter.

If a single circular knitting machine changes a number of nominal dimensions easily on the monitor side, there is no need to stop or store the machine, thereby reducing the number of holdings. Is economically very advantageous.

To this end, it was a problem to keep the replacement parts of the knitting portion to a minimum and to commonize the mounting positions of the replacement parts.

The present invention has been made to solve these problems, and an object of the present invention is to provide a circular knitting machine which can change a number of nominal dimensions with one circular knitting machine.

At least one row of mounting holes in the radial direction is provided with one row of mounting holes, thereby dividing at least two dimensions of each adjacent dimension by group and commonizing the cam ring within the group, so that a number of nominal dimensions can be achieved with one circular knitting machine. It is characterized by being changeable. According to another aspect of the present invention, the cam segment in the circular knitting machine having a cam segment for operating the knitting sphere in each feeding hole and an annular body cam retaining the cam segment is mounted from the cam action surface. At least two kinds of different lengths up to the above are prepared, and the cam ring is provided with at least one row of mounting holes in the radial direction of the mating member on which the cam segment is mounted, whereby at least two dimensions of adjacent angular dimensions are thereby provided. It is characterized by the fact that it is possible to change the number of titles by one circular knitting machine by dividing each group into a group and by commonizing the cam ring in one group.
