Note that, since the presser foot 42 presses the raw yarn 2 with a very small force, the backward movement of the raw yarn 2 conveyed by the conveyor belt 37 by the trowel is not delayed under the presser foot 42.

Further, a needle shaft (not shown) that moves the sewing needle 43 of the sewing machine 40 up and down is operated in response to the movement of the main shaft, and moves the sewing needle 43 with a certain periodic deviation with respect to the thread feed conveyor 36. It is supposed to be done.

In addition, as shown in FIG.
5 falls from the rear end of the upper surface of the rear machine base 22 and is housed therein.

Now, how to use the endless tassel manufacturing machine configured as described above will be described in detail below.

First, as shown in FIG. 1, the untwisted yarn 2 wound around the bobbin 1 is guided into the yarn twisting device 7 via the guide roller 6 (as shown in FIG. The yarn twisting member 16 is inserted through the front yarn insertion hole 14 in the yarn twisting device 7.
The thread is inserted into the thread twisting hole 16a of the thread twisting device 7, and the thread is pulled out of the thread twisting device 7 through the thread insertion hole 15 at the rear thereof.

As shown in FIG. 1, the raw yarn 2 is drawn out of the yarn twisting device 7 and then passed through the flyer 23 via the yarn guide tube 24. Then, as shown in FIG.
The tip of the raw yarn 2 pulled out from the tip is tied in a ring shape, and this is fitted into any one of the yarn take-up protrusions 2B protruding from the rotating belt 27 of the yarn hooking device 25, and the yarn distribution work is completed. do.

Once the yarn distribution work is completed, the manufacturing machine is started.

Then, as described above, the yarn twisting member 16 is rotated by the timing belt 21. At this time, the thread hook also rotates the rotating shaft 32 of the device 25, causing the rotating belt 27 to move in the direction of the arrow in FIG.

Therefore, as shown by the two-dot chain line in FIG. The yarn is then sent to the rear through the yarn twisting process.

As mentioned above, the flyer 23 and the thread hooking device 25 move synchronously. To describe the synchronous motion in more detail according to FIG. 3, the flyer 23 rotates between one horizontal position U and the other horizontal position D (or from the other horizontal position to one horizontal position U). In between, the thread take-up device 259 and the rotating belt 27 are connected to the thread take-up protrusions 2 located in the front and back in the same row.
Move backward by a distance of 4 minutes. Therefore, after the flyer 23 has completely rotated in one direction, when the flyer 23 starts rotating in the other direction, the raw yarn 2 is captured by the capture portion 31 of the thread take-up projection 28. By repeating this thread-taking operation, the raw yarn 2 is held in a zigzag pattern on the thread-taking projections 28, 29 on the rotary belt 27, and the thread-taking process is performed.

As shown in FIG. 6, as the rotating belt 27 moves, the yarn take-up protrusion 28 to which the tip of the yarn 2 is fixed moves backward from the flat plate portion 35 of the yarn lifting plate 34. The rear end moves backward on the thread lifting plate 34 and reaches a position higher than the catching section 31. Therefore, the annular portion at the tip of the yarn 2 separates from the catching portion 31 of the thread take-up projection 28, and the yarn 2 sequentially separates from the other yarn take-up projections 28 as well.
It stagnates while maintaining a zigzag shape upwards. Note that even if the annular portion of the yarn 2 is detached from the thread take-up protrusion 28 , it is retained in a zigzag pattern by a large number of thread take-up protrusions 28 located in front of the flat plate part 35 of the yarn lifting plate 34 . Since the catching portion 31 exhibits an excellent frictional effect and locks the yarn 2, the yarn 2 is not pulled forward by the flyer 23 or the like and does not move backward.

When the yarn 2 is stagnant on the entire surface of the yarn lifting plate 34, the yarn lifting plate 34 is covered by the amount of yarn 2 newly detached from the yarn take-up protrusion 28.
The raw yarn 2 on the upper end is pushed onto the yarn feed conveyor 36 at the rear. By continuously performing this operation, the fourth
As shown in the figure, the raw yarn 2 is gradually fed onto the yarn feed conveyor 36. In addition, as mentioned above, the yarn feed conveyor 36
Since the thread hook rotates at a slower speed than the device 25, the raw thread 2 is fed backwards on the thread feed conveyor 36 in a dense zigzag pattern.

The raw yarn 2 is sent backward by the yarn feed conveyor 36,
When the needle shaft reaches the position directly below the head 41 of the sewing machine 40, the needle shaft receives the movement of the main shaft, and the sewing needle 43 moves into the needle recess groove 39.
Starts crawling inside. Therefore, the step of sewing the raw thread 2 is performed, and the endless tuft 45 is formed. And Mudanbo 45
is sent to the rear on the yarn feed conveyor 36, and is sent to the rear machine base 2.
2 falls from the rear end and is stored in the receiving box 46. This endless tuft 45 is manually cut to a required amount for use.

In the endless tassel making machine described above, the thread twisting process, thread taking process, and sewing process are performed in a series of operations, so the operation of this machine is simple.

Also, from the front to the rear of the manufacturing machine, the thread twisting device 7, shape holding means 23, 25, and sewing machine 40 that are involved in the above three processes are
■It is easy to check the condition of this machine during trial operation. ■Furthermore, when a defective product occurs, by checking the process that corresponds to the defective part, it is easy to check the parts that are involved. Repairs to the machine are therefore easily carried out.

Also, unlike conventional products, the bobbin 1 is placed in front of the front side of the machine base 3 so that it does not move onto the mounting plate 4, so the weight of the bobbin 1 places a heavy burden on other parts. There aren't many.

Effects of the Invention As detailed above, the present invention includes a yarn twisting device for twisting raw yarn consisting of a plurality of thin yarns extending from a bobbin, and a similar twisting device to hold the twisted raw yarn in a zigzag shape. and a sewing machine that continuously sews the zigzag-shaped yarn sent from the shape-retaining means through a thread feeding member to form an endless tuft, and furthermore, the bobbin is immovable. This provides an excellent effect in that there are fewer breakdowns and furthermore, the service life is extended.
