As shown in FIG. 6A, the knitting yarn is not woven in the first feeder F1 at the time of wet wetting, and the knitting yarn fed from the first yarn switching device 40-1 is applied to the second feeder F2. Supplied. Therefore, when the newly supplied knitting yarn reaches the A position, the switching timing is too early in the normal position where the cutter operates, and satisfactory switching is not performed. When the newly supplied knitting yarn reaches the B position, the switching should be performed.

The opening and closing motion of the yarn cutters 14-1 and 14-2 and the yarn catcher 14-3 is caused by the action of the switch cam 21-5 and the cutter cam 4. In this invention, the position of the processus | protrusion of the switch cam 21-5 for opening / closing these was set in the different position in the 1st yarn feed switching device 40-1 and the 2nd yarn feed switching device 40-2. In addition, two kinds of cutter cams 4, namely, the cutter cams 4-1 for the first rapid-switching device 40-1 and the second sudden-switching corresponding to the projection positions of the switch cams 21-5, respectively. The cutter cam 4-2 for the apparatus 40-2 is provided. In this invention, arrangement | positioning of two types of switch cams 21-5a and 21-5b and two types of cutter cams 4-1 and 4-2 is important.

The newly yarn-feeding knitting yarn NY captured by the trapper 15 is disposed between the first yarn feeding switching device 40-1 and the second yarn feeding switching device 40-2, and is provided with the thread guide member 16. Passes through the bottom surface.

In addition, as shown in FIG. 5B, as the trapper 15 moves, the knitting yarn is at an uphill inclined surface of the thread guide member 16 at about an intermediate point between the steep yarn switching device and the yarn carrier 37. It rises along the guide surface 16-1, and reaches the holding | maintenance part 16-2 of the recess shape. At this time, the edge part of the knitting yarn NY captured by the tip protrusion 15-1 of the trapper 15 is guided to the yarn carrier 37 and then captured by the hook portion of the knitting needle.

After that, the yarn catcher 14-3 is opened and released from the end of the yarn held by the yarn catcher 14-3. At the same time, since the previous knitting yarn OY woven so far is maintained and cut, the knitting yarn enters the opening of the yarn catcher 14-3, and moves circumferentially in the circumferential direction with the knitting machine, as shown in FIG. Cutter cams 4-1 and 4-2 push the switch cams 21-5a and 21-5b to move with the yarn catcher 14-3 through the link members 6, 7, 8 and 9. The blade 14-2 is closed.

This invention can be implemented only by changing a part to the conventional circular knitting machine, and can also return to the conventional machine from the implementation machine of this invention.

When changing to the conventional machine as shown in FIG.6 (b) by the implement machine of this invention, when the knitting yarn reaches the X position shown in FIG.6 (b), the cutter cam 4 will turn into the 1st switch cam 21. FIG. -5a) and the standard cutter cam 4 (refer to FIG. 2C) which act at the same timing with respect to the 2nd switch cam 21-5b. The standard cutter cam 4 is preferably widened to act on the projection position of both the first switch cam 21-5a and the second switch cam 21-5b. In FIG. 2C, the first switch cam 21-5a and the second switch cam 21-5b are shown for convenience, but the first switch cam 40-1 is actually the first switch cam 40-1. The second switch cam 21-5b is coupled to the second sudden yarn switching device 40-2, respectively.
