（図３、図４の）。The operation of the yarn guiding device of this embodiment will be described. A steering cam 56 having a raising cam 52, knitting cams 53 and 54, and a guide cam 55 shown in FIG.
And a carriage 45 having a thread holding member control cam 48
The case where the yarn is guided rightward and the yarn is guided to the back surface of the needle will be described. When guiding the yarn to the back side of the needle, the yarn pressing member control cam 48a located on the leading side in the traveling direction is used. As the carriage 45 moves to the right, the control butt 37 of the thread pressing member 35 slidably inserted in the thread pressing member support bed 26 is inserted into the cam groove 47 (see FIGS. 3 and 4). As the carriage continues to advance, the needle jack butt 10 passes through the lowermost position of the knitting cam 54, and the needle is kept at the generally previous position, and the control butt 37 of the yarn pressing member 35 engages with the cam mountain of the yarn pressing member control cam. Together, they rise and advance the yarn pressing member toward the needle bed gap 42. By the advance of the thread pressing member 35, the protruding portion 39a at the tip of the arm 39 is disengaged from the engagement with the band 44, and the sliding resistance in the groove of the thread pressing member 35 disappears.
At the same time, the recess 40 of the thread pressing member 35 is not
3, the coil spring 43 is deformed against the elastic bias. The yarn pressing member 35 advances at the same time on both the front bed side and the back bed side (see FIGS. 3 and 4).

ない。The yarn supplied to the needle bed gap due to the advance of the yarn holding member 35 into the needle bed gap 42 is the action surface 3 of the yarn holding member.
6 is abutted against and is pushed down from both sides, and is located at the lowest position of the working surface 36. This position is below the rising trajectory of the rising needle. Next, the needle jack butt 10 raises the slope of the lasing cam 52 and raises the needle, but since the yarn is below the locus of the needle rise, the needle is raised by locating the yarn on the back surface of the needle and raising the needle. No thread is hung on the hooks (see FIGS. 3 and 4). With the subsequent movement of the carriage, the control bat 37 moves down the cam lobe by the retreating cam 49a and retreats to the initial position to position the thread on the back surface of the needle (in FIGS. 3 and 4). In this state, the protruding portion 39a of the arm 39 is pressed against and engaged with the band 44, so that the yarn pressing member 35 does not move in the groove.

（図３、図５のＤ）。Next, the case where the yarn is guided to the hook will be described. When guiding the yarn 51 to the hook, the yarn pressing member control cam 48b located on the trailing side in the traveling direction is used. The operation of the arm 39 and the coil spring 43 associated with the forward / backward movement of the thread pressing member 35 is similar to the above case. As the carriage 45 moves to the right, the needle passes the top of the raising cam 52 and is held by the yarn pressing member 35 at the upper edge of the needle when it is about to be pulled down by the knitting cam 53. In FIG. 3, the control butt 37 of the yarn pressing member corresponding to the needle descending the slope of the raising cam 52 raises the cam crest of the yarn pressing member control cam 48b (A in FIGS. 3 and 5). As a result, the thread pressing member 35 advances the action surface 36 from both sides with respect to the thread of the needle bed gap and presses the thread against the inside of the hook of the needle at the most advanced position. At this time, the needle has started descending (B in FIGS. 3 and 5). Working surface 3
The needle further descends with 6 being most advanced (Fig. 3,
5C), the yarn 51 is completely caught by the hook of the needle 8, the yarn pressing member 35 is completely retracted, and the needle is also lowered (D in FIGS. 3 and 5).

ム４９ｂだけを操作手段に設ければよい。While the yarn pressing member control cam 48 moves the yarn pressing member 35 forward and backward in association with the knitting operation as described above, the position of the yarn pressing member 35 with respect to the needle bed gap is all under the control of the control cam 48. Thread guide device 3 of the present embodiment
In the case of No. 3, the retracted position of the thread pressing member 35 is a position further retracted from the retracted position by the coil spring 43 as shown in FIG. 4, and at this position, the tip of the arm provided on the thread pressing member 35 is a band strap. Since the yarn pressing member 35 is pressed against the carriage, the position of the yarn pressing member 35 on the support bed is stable even after passing through the carriage. Further, even if the worker moves the yarn pressing member 35 to the advanced position during the knitting machine adjustment, the coil spring constantly receives the retracting action, so that the front and rear yarn pressing members collide with each other even if the needle bed is racked. There is no such thing. In the above-described embodiment, the retracting means provided on the thread pressing member retracts the thread pressing member only to a position that does not exceed the center line of the needle bed gap. It is also possible to set the member control cam 48 to the retracted position by the retracting cam 49a, and in this case, only the advancing cam 49b of the yarn pressing member need be provided in the operating means.

ることはいうまでもない。The advancing cam 152 is switched in its operating state by the driving means upon receiving a command from the controller when the traveling direction of the carriage is reversed. Further, even when performing the racking operation of the needle bed with the carriage positioned on the needle bed, the drive means is operated before the racking command from the controller, and the left and right advance cams 152a and 152b are set to the retracted position. To be done. This means that the yarn pressing members can be retracted regardless of the position of the carriage on the needle bed, and interference between the yarn pressing members during racking can be prevented. Further, for example, when the interference with the yarn feeder in the stopped state on the needle bed poses a problem, the retreat amount may be further increased. The advancing amount of the advancing cam 152 can be selected differently depending on whether the yarn is guided to the hook of the needle or when the yarn is guided to the back side of the needle. Although the preferred embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to the above embodiments and can be implemented without departing from the spirit of the present invention.
