から構成されている。The folding assisting means 20, 30 have a bilaterally symmetrical structure. For convenience, only the left side device 20 will be described with reference to FIGS. 3 and 4, and the right side device 30 will not be described. The folding assisting means 20 includes a standing plate 22 having a substantially arcuate shape which is vertically installed upright on an elongated base plate 21 fixed to the sewing machine 18 or a carriage on which the sewing machine 18 is mounted, and the standing plate 22.
Arcuate slot 23 formed on the upper side of the upright plate 22, a two-step cam 24 formed on the outer side of the upright plate 22 and composed of a high position part 24a and a low position part 24b, and an operating rod 2 of an air cylinder 25 of the reciprocating drive means.
5a, a main rocking plate 26 that is connected to the pin 5a by a reciprocating motion and rocks along the arcuate slot 23, and the standing plate 2.
The upper gripping body 27, which is rotatably supported on the main oscillating plate 26 via the bearing 27a so as to be able to roll in the inner concave portion of 2, and is pivotally supported on the main oscillating plate 26 so as to be swingable (a fulcrum P1). The control rod 28b pivotally supports the trochanter 28a, which moves along the two-step cam 24 during the reciprocating operation of the air cylinder 25, at the outer end, and is separated from the upper gripping body 27 at the cam high position 24a and the cam low position 24b. A sub-oscillation plate 28 bearing a rollable lower gripping body 29 that is displaced so as to be able to contact the upper gripping body 27 by
The lower gripping body 29 is constituted by a spring 29a as a biasing means for biasing the lower gripping body 29 so as to contact the upper gripping body 27 at the cam lower portion 24b.

る。The folding assisting means 20 is installed so that the center P2 of the arc of the arcuate slot 23 coincides with the center of the trumpet tube 15. Further, the center P2 of the arc is configured to coincide with the lower tip of the lower hemisphere 27b forming the upper grip 27. The lower gripping body 29 is composed of a rolling cylinder, and is biased by the spring 29a at the position of the lower position 24b so as to swivel around the pivotal fulcrum P1 together with the auxiliary swinging plate 28 so as to be in contact with the upper gripping body 27. Grasp A1, (A2). That is, when the air cylinder 25 contracts, both gripping bodies 2
Hold the ears A1, (A2) of the running towel A between 7 and 29, and turn the ears A1, (A2) slightly inward while turning about 50 ° clockwise around the center P1. .

れる。The timing at which the air cylinder 25 is contracted to start the bending assist work is the thickness sensor 11, (12) mounted on the upstream frame 5a of the machine base 5.
After detecting the boundary between the pile woven portion c and the border portion b at the step, the fixed distance L from the sensor position to the gripping body position is converted into pulses by the pulse encoder corresponding to the towel traveling speed, and the correspondence is calculated. It is the time when the number of pulses is reached. Similarly, the border part b passes through the thickness sensors 11 and (12), and the boundary between the border part b and the next pile weave part c is also detected at the step, and the number of pulses corresponding to the border part is calculated. When the number of pulses is reached, the air cylinder 25 is extended to cancel the bending work. These operations are responsive and efficient because the operating parts are relatively small. The ears A1 and A2 of the folded border part b enter the trumpet tubes 15 and 16 immediately downstream while maintaining the folded state because the towel A itself is an inelastic material, and the weave density is greatly compared. Even if it is hard, it will be completely folded in three for a beautiful sewing finish. In addition to the above-described embodiment, a configuration in which bending is assisted after a slight pull is applied to the lateral outside is also adopted depending on the towel.

仕上がりを得ることができる。As described above, according to the sewing machine for the side edge portion of the long product of the present invention, the ear of the high hardness broad towel, which is one of the long products, of the relatively hard border part having a high weaving density. Since a folding assist is previously received by the folding assisting means and the guide is guided to the folding means, it is possible to fold it into three beautiful pieces and obtain a good sewing finish.

成もタオルに応じて採用される。The timing at which the air cylinder 25 is contracted to start the bending assisting work is the thickness sensors 11 and (12) mounted on the upstream frame 5a of the machine base 5.
Detects the boundary between the pile weave portion c and the border portion b at the step, and then determines the constant distance L from the sensor position to the grip body position corresponding to the towel traveling speed by the pulse of the moving distance detecting means. It is the time when the corresponding pulse number calculated by converting the pulse by the encoder is reached. Similarly, the border part b passes through the thickness sensors 11 and (12), and the boundary between the border part b and the next pile weave part c is also detected at the step, and the number of pulses corresponding to the border part is calculated. When the number of pulses is reached, the air cylinders 25 and 45 are extended to cancel the bending work. These operations are responsive and efficient because the operating parts are relatively small. The ears A1 and A2 of the folded border part b enter the trumpet tubes 15 and 16 immediately downstream while maintaining the folded state because the towel A itself is an inelastic material,
Even if the weaving density is high and it is relatively hard, it will be completely folded in three for a beautiful sewing finish. In addition to the above-described embodiment, a configuration in which bending is assisted after a slight pull is applied to the lateral outside is also adopted depending on the towel.
