As shown in FIGS. 1 to 4, the present invention provides a yarn feeder 20 for a flat knitting machine whose yarn feeding position can be changed. The flat knitting machine yarn feeder 20 is used in the area set between the two needle beds 11 and 12 in the flat knitting machine 100. Further, the yarn feeder 20 for a flat knitting machine according to the present invention includes a drive mechanism 21 and a yarn feeder mechanism 22, and the drive mechanism 21 includes a motor 23 and a drive plate 24 connected to the motor 23. .. The motor 23 receives an electronic signal and is controlled when the knitting conditions of the flat knitting machine 100 are changed. The drive plate 24 moves linearly in conjunction with the motor 23.

Further, as shown in FIGS. 2 to 4, the thread feeding mechanism 22 includes a transition plate 25 connected to the drive plate 24 and a thread feeding arm 26 assembled to the transition plate 25. The transition plate 25 is configured to move according to the drive plate 24. In one embodiment of the flat knitting machine yarn feeder according to the present invention, the drive plate 24 is provided at the end of the transition plate and includes a protrusion 241 projecting toward the transition plate 25, and the transition plate 25 is a protrusion. A mounting rail 257 for providing the portion 241 is provided, and the mounting rail 257 does not need to be provided with a portion having undulations, and the protruding portion 241 may be provided so as to interlock the transition plate 25.

Further, the transition plate 25 includes a guide hole 251 other than the circular hole. In one embodiment of the weft knitting machine yarn feeder according to the present invention, the guide holes 251 are provided with two slopes 252 and 253 provided opposite to each other, and the two slopes 252 and 253 are supplied for the flat knitting machine.
