きる。As shown in FIG. 12, these devices sew the upper fabric 1 and the lower fabric 2 together (i.e., side stitch), and then sew the upper fabric 1 and the lower fabric 2 together. The side seam portion can be sewn by folding back the sections 1a and 2a so as to open them, and then making a crease 3 along the folding line.

3にアイロン効果を付与するものであった。However, in these conventional devices, after folding the side-stitched seam allowances 1a and 2a in opposite directions, a heating puller heated by an electric heating element (heater) is used to form a crease 3 along the folding line. Alternatively, an ironing member such as an iron is brought into pressure contact with the cloth, and its heating action imparts an ironing effect to the folds 3.

常に悪いという問題点があった。(Problems to be Solved by the Invention) In the conventional device described above, since the iron member is heated by an electric heating element, it takes a long time to heat the iron member to the operating temperature at the start of sewing, and also takes a long time to dissipate the heat at the end of GI sewing. There were problems in that the hat took a long time, it was difficult to control the temperature, and the workability was very poor.

され、使用上の安全性に問題があった。In addition, during sewing work or when cleaning the cloth after sewing, the electric heating element and ironing member are in a heated state, so the worker's fingers may come into contact with them and get burnt, or the cloth may come into contact with them. It is predicted that if the fabric is left in contact with the fabric for an unnecessarily long period of time, the fabric may become scorched, or in extreme cases, it may cause a fire, which poses a problem in terms of safety in use.

10上の突出ビン30が係入される。The heavy punishment member 7A is formed in the shape of an L-shaped plate, is attached to the upper surface of the right rear portion of the throat plate 10 with a mounting screw 27, protrudes forward from the left end thereof, and is attached to the presser foot 11. It has a heavy punching part 28 adjacent to the right side of the presser foot part 23 and the presser tongue piece 25. The front end of the heavy-duty portion 28 is shaped like a square whose thickness decreases toward the tip. The heavy punching part 28 of the heavy punching member 7A is connected to the sewing machine main body 6.
With the movement of the fabric fed out in conjunction with the stitching by the feeding mechanism (this movement is referred to as stitching movement of the fabric),
It intervenes relatively between the seam allowances 1a and 2a of the sewn fabrics 1.2, and moves the seam allowances la and 2a in opposite directions.
That is, the seam allowance 18 of the upper cloth 1 is guided upward, and the seam allowance 1b of the lower cloth 2 is guided downward (see FIGS. 8 and 9). Note that the protruding bottle 30 on the throat plate 10 is inserted into the horizontally elongated hole 29 of the heavy punishment member 7A.

The lower cloth folding member 7B has a substantially rectangular plate shape, a support portion 781 at its left end protrudes to the left, and has a chamfered guide slope 31 at its left end. Lower cloth folding member 7B
The guide slope 31 folds back and guides the seam allowance 2a of the lower cloth 2 guided by the heavy chamfer 447A (see FIG. 9). That is, the seam allowance 2a of the lower cloth 2 held by the upper cloth 1 is first bent downward by the action of the guide slope 31, and then folded back and guided to the upper surface of the support portion 781. In order to facilitate folding of the seam allowance 2a of the lower cloth 2, it is desirable to chamfer the front edge of the lower cloth folding member 7B and the guide slope 31.

It is attached by mounting screws 32. Upper cloth folding member 7
The lower part of C extends obliquely downward to the right and forward while bypassing the rear of the cutout surface 26 of the presser foot 11, and its tip part applies its own elasticity to the upper surface of the heavy punishment member 7A. The guide portion 33 is brought into contact with the guide portion 33. The guide portion 33 of the upper cloth folding member 7C folds back and guides the seam allowance portion 1a of the upper cloth 1 guided by the heavy punishment member 7A (eighth

The inside of the water supply channel 50 is filled with a water supply member 51 such as cotton or fiber, and the upper end thereof is communicated with a water supply tank 53 via a communication pipe 52. In addition,
The water supply tank 53 is installed on a thread winding stand so that water naturally flows down to the water supply channel 50.
上記した縫い割りミシンにより布の脇縫い部をvIMす

発振を開始する。When the sewing machine main body 6 is operated (operated) to proceed with sewing while overlapping the side seams of the upper fabric 1 and the lower fabric 2, first, as is well-known, the upper fabric 1 and the lower fabric Cloth 2 is sewn together. At the same time, the lifting cylinder 38
lowers the ultrasonic generator 8, and its vibrator starts oscillating.

。Thereafter, as both fabrics 1.2 are sewn and moved while the sewing line of both fabrics 1.2 is pressed by the presser tongue piece 25 of the presser foot 11, as shown in FIGS. 6 and 8. The seam allowance 1a of the upper cloth 1 is connected to the guide portion 3 of the upper cloth folding member 7C.
3 and then folded back along the presser tongue piece 25. At this time, the seam allowance portion 1a passes through the gap between the guide portion 33 of the upper cloth folding member 7C and the cutout surface 26 of the presser foot 11.

49との間に侵入可能である。At the same time, the seam allowance 2a of the lower cloth 2 is first bent downward by the guiding slope 31 of the lower cloth folding part 07B, and then supported by the action of the guiding slope 31 of the lower cloth folding member 7B. Part 781 and cloth dividing part 2 of cloth dividing member 7△
It is folded back by 180 degrees and arranged between the side surfaces of 8 and 8. This folding is performed along the seam line located below the presser tongue piece 25 (see FIG. 9). The folded portions of the seam allowances 1a and 2a of both the cloths 1 and 2 folded back in this manner are guided along the presser tongue piece 25 to the tip of the output horn 8A. As shown in FIG. 2, the tip of the output horn 8A is inclined upward to the right, so that the folded portions of the seam allowances 1a and 2a can easily connect the tip of the output horn 8A and the anvil 49. It is possible to get in between.

When the anvil 49 is pressed (=I) with both the cloths 1 and 2 interposed between the tip of the output horn 8A and the anvil 49 is pressed (=I), the ultrasonic generator 8 is applied, resulting in its output horn 8A
The cloth itself at the abutting portion generates heat, and the fold 3 is imparted to the cloth 1.2 by the ironing effect of the heat.

The heat generation of 2 occurs in the cloths 1 and 2 only when the cloths 1 and 2 are held between the output horn 8A and the anvil 49, so unlike the conventional electric heating element, instantaneous heating and instantaneous Heat dissipation can be realized, and the heat m can also be easily controlled by changing the frequency.
従って、その温度制御が容易で、作業性が向上される。Therefore, temperature control is easy and workability is improved.

いう効果がある。(Effects of the Invention) That is, according to the present invention, immediately after the upper fabric and the lower fabric are sewn together by the operation of the sewing machine, the guiding means sequentially moves the seam allowances of both sides in opposite directions as the stitching moves. Immediately after the folding, the ultrasonic vibration of the output horn of the ultrasonic generator is applied along the folding line, and the cloth itself in contact with the output horn generates heat. Creases are created by the ironing effect of heat, and ultrasonic vibrations from an ultrasonic generator are used to create the creases, which generates heat in the fabric itself, unlike conventional methods using electric heating elements. It is possible to achieve instantaneous heating and instantaneous heat dissipation, and the amount of heat can be easily controlled by changing the vibration frequency, improving workability, and since the output horn itself does not generate heat. , on the same horn! Al1 The fear of burns caused by touching the hands and fingers of al1 workers, and the fear of scorching and fire caused by contact with cloth are eliminated, and there is an effect that safety in use is improved.
