In other words, the butt 4a is advanced along the outer edge of the right side lug removal cam 33a to the lug removal position, and is moved back slightly along the outer edge of the right side chevron-shaped cam 32a, and then the feeder remains stationary at a predetermined position. Knitting yarn Y is supplied from the yarn end body 59 to the hook 4b of the main needle 4. Then, the butt 4a of the main needle 4 is retracted along the inner edge of the left knockover cam 40b to the knockover position, and the stitch adjustment dial 5 shown in FIG.
In step 4, stitches of a preset size are formed continuously and quickly.

When the butt 4a faces the left knitting needle selection device 37b, the rotation direction of the motor 114 is reversed, and the electromagnet 36b of the knitting needle selection device 37b
is excited, the carriage 8 is moved in the opposite direction of the arrow in FIG. 12 (to the left in FIG. 11), and the main needle group in the knitting working section where the knitted fabric is suspended is moved based on the operation of the knitting needle selection device 37b. The butt 4a is introduced into the second guide passage A-C-A, and the next stage of stitches is continuously formed.

On the other hand, in order to perform rubber knitting by alternately forming front stitches and back stitches in the lower part of the knitted fabric K shown in FIG. When knitting the surface stitches using the body 46, as the carriage 8 continuously moves in the direction of the arrow, the stitches are suspended based on the operation of the right knitting needle selection device 37a, as is clear from FIGS. 4 and 12. The butts 4a of the main needle group in the knitting operation section (butts 4a indicated by black circles in FIG. 12) are introduced into the first guide path A-B-A. When the knitting stop button 4a (butt 4a indicated by a white circle in FIG. 12) adjacent to the left end needle 4 in the knitting operation section is introduced into the notch 46a of the single needle operating body 46, the electromagnets S1 and S2 are activated. The excitation state is determined, and the feed switching plate 93 is placed in the left position as shown in FIG. 8a.

As is clear from FIG. 3, when the rotary cam wheel 112 rotates once from the state where the permanent magnet 130b on the first cam wheel 110 faces the cam stop position detection sensor 131b, the permanent magnet 130b on the first cam wheel 110 rotates once as shown in FIG. According to the cam shape of the drive cam 170, the feed plate 101 is reciprocated back and forth once. Therefore, as is clear from FIG. 8a, the lower ratchet wheel 91 is rotated clockwise by the locking portion 103b of the left feed pawl member 103, and the pinion 10, rack 11, and sphere cooperate with each other. As a result, the carriage 8 is moved step by step in the direction of the arrow in FIG. 12 by one pitch of the main hands 4. Then, the butt 4a of the left end needle 4 in the knitting operation section is introduced into the notch 46a of the single needle operating body 46.

Thereafter, as the rotating cam wheel 112 rotates, one main needle 4 is moved back and forth between the knock-over position and the tongue-out position via the single-needle operating body 46 and the like, and the yarn feeder body 59 and The latch engagement plate 60 is moved vertically and horizontally. That is, after the yarn feeder body 59 is moved from the left side to the right side of the main needle 4 and the yarn feeding operation is performed with respect to one main needle 4 located slightly behind the tongue removal position, The main needle 4 is retracted to the knockover position and a new stitch is formed.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, it is possible to provide separate driving bodies for the stepwise feed device and the continuous feed device, or to provide a fixed arrangement of the movable bodies and to transport the support body. It is also possible to arbitrarily change the configuration of each part without departing from the spirit of the present invention, such as by configuring it so that it is fixed or by configuring the first and second switching wheels with contact rollers.

Effects As detailed above, the present invention obtains the driving power of the driving body in the transfer device of a hand-knitting machine, and moves the support body and the working body stepwise at regular intervals relative to each other in the longitudinal direction of the support body. and a continuous feeding device that obtains driving power from a driving body and relatively and continuously moves the supporting body and the movable body in the longitudinal direction of the supporting body, for example,
It has the advantage of being able to easily handle knitting that requires relatively continuous feed, such as continuous front knitting, typified by flat knitting, and knitting that requires relative incremental feed, such as increasing and decreasing stitches, preventing down-setting, and rubber knitting. It has a great effect.

Furthermore, by providing both of the above-mentioned feeding devices and a power transmission switching device for separately transmitting the drive power of the driving body to each feeding device, it is possible to easily switch between continuous feeding and incremental feeding. This provides an excellent effect in that each feed can be carried out reliably.
