With such a configuration, the knitting described in the first embodiment is possible also in this embodiment.

Further, in the first embodiment, when the two yarn carriers 18 come close to each other at the end of the yarn path rail 22, the movable yarn guide 40 between the yarn carriers 18 contacts the side face of the yarn carrier 18 which has been stopped. The carrier carrying pin 26 of the carriage 6 was controlled so as not to come into contact with it. Also in this embodiment, when the movable yarn guide 60 between the yarn carriers 62 comes into contact with the stopped yarn carrier 62, the pin 68 of the movable yarn guide 60 is pulled down. Therefore, when one yarn carrier 62 is moved, the yarn carrier 62 is moved by the movable yarn guide 60.
There is a situation where you can't take you. Also in the third embodiment, as in the first embodiment, the carrier carrying pin 2 is used.
It is also possible to perform the control of No. 6, but it is also possible to adopt a configuration in which each yarn carrier 62 is provided with an abutting member 80 as shown in FIG. Abutting member 80 provided on the yarn carrier 62
Is a length such that when the two yarn carriers 62 contact each other by the contact members 80, the movable yarn guide 60 between the yarn carriers 62 does not contact the stopped yarn carrier 62. Further, the cam 82 for disengaging the carrier carrying pin 26 and the yarn carrier 62 provided on the upper portion of the yarn carrier 62 is also extended. As a result, the contact member 80 of the yarn carrier 62 that is transferred is brought into contact with the contact member 80 of the yarn carrier 62 that has been transferred and stopped at the end of the yarn path rail 22, and the yarn carrier 62 stops. Further, the engagement between the yarn carrier 62 that has moved and the carrier-carrying pin 26 of the carriage 6 is released by the extended cam 82 above the yarn carrier 62 that has stopped.
Such a configuration is also possible in the first embodiment.

In each of the embodiments, the thread guide stopper is fixed to the longitudinal center of the thread guide rail by screwing, but the thread guide rail is provided with a dovetail groove so as to be movable in the groove. The guide stopper may be fixed with screws. By doing so, when the yarn is fed from one end of the knitting machine, the yarn guide stopper can be set at an appropriate position according to the knitting width and the like.

In each of the embodiments, the yarn is fed to the yarn carrier from both sides of the knitting machine, but the yarn may be fed from one end of the knitting machine. In that case,
Regardless of the number of yarn carriers to be used, the movable yarn guide may be supported on the yarn guide rails on the yarn supplying side of the yarn carriers supported by the yarn guide rails.

[0046]

As described above, according to the present invention, the yarn supplied to the yarn carrier from the end of the knitting machine is supported by the movable yarn guide in the middle thereof, and the distance between the supporting yarns is shortened.
It is possible to prevent the unevenness of the stitches due to the entanglement with the adjacent yarn or the change of the yarn tension, which is caused by the slackness or the shake of the yarn. Further, even when knitting using a plurality of yarn carriers, since the plurality of movable yarn guides on the yarn path rail are not integrated but independent of each other, the moving region of the yarn carrier is not limited by the movable yarn guides. A knitting operation in which yarn carriers approach each other can be performed without any problem. In addition, it is sufficient to support the movable yarn guides on the yarn path rail in the required number according to the knitting method.

Further, according to the present invention, the movable yarn guide is carried by the yarn carrier by utilizing the attraction force of the magnet. Therefore, it is possible to easily carry the movable yarn guide by the yarn carrier without requiring a complicated mechanism.

Further, according to the present invention, the entrainment of the movable yarn guide by the yarn carrier can be released by the attraction force of the magnet.

Further, according to the present invention, the movable yarn guide is entrained by the yarn carrier by fitting the engaging piece of the movable yarn guide into the recess formed in the engaging portion of the yarn carrier. Therefore, it is possible to reliably carry the movable yarn guide by the yarn carrier.
