回転針が過熱して生地の焦げ目がひどくなり、合
成繊維等は溶融することもある。Problems to be Solved by the Invention In order to perform such perforation work efficiently, it is necessary to increase the number of layers of fabric, but this makes it difficult for the rotating needle to pass through the fabric. In particular, if the fabric is clogged, the passage of the rotating needle will be even more difficult. For this reason,
The power to rotate the rotating needle increases, and if you forcefully screw in the rotating needle, thread breakage may occur in the fabric.
The rotating needle may overheat, resulting in severe browning of the fabric and melting of synthetic fibers.

促進させることになる。Effect: Therefore, acceleration in the axial direction occurs in the metal needle 11 due to the ultrasonic vibration. In particular, by intermittently vibrating the metal needle, the amplitude and acceleration peaks are concentrated at the start of the vibration generation, and the penetrating action of the metal needle 11 into the fabric 1 is promoted.

First, stack many pieces of fabric 1, and then put base 2 on top of it.
Press down. A see-through window 3 is formed in the base 2, and a transparent plate 5 having a small hole 4 is provided in the see-through window 3. Further, a slider 7 is slidably fitted into a shaft 6 erected from the base 2, and a case 10 containing an ultrasonic vibrator 9 is mounted on a support portion 8 fixed to the slider 7. It is provided. Further, a holder 12 that holds a metal needle 11 is connected to the ultrasonic vibrator 9. Furthermore, a cable 13 is held at the upper end of the case 10 to connect the ultrasonic vibrator 9 to an ultrasonic vibration source (not shown).

is vibrated in the axial direction, and the case 10 is lowered together with the slider 7. Acceleration in the axial direction occurs in the metal needle 11 due to the ultrasonic vibration at this time. In particular, as shown in FIG. 2b, the ultrasonic vibration source is driven by a pulse control signal, and the ultrasonic vibrator 9 is intermittently vibrated together with the metal needle 11, thereby generating vibrations as shown in FIG. 2a. The amplitude and acceleration peaks can be concentrated at the start of the generation. Therefore, the penetrating action of the metal needle 11 into the fabric 1 can be promoted. metal needle 11
By vibrating it when pulling it out from the dough 1, the resistance can be reduced and it can be pulled out easily.

である。Effects of the Invention As described above, this invention causes a metal needle to be intermittently vibrated by an ultrasonic vibration source, and the metal needle that intermittently vibrates in the axial direction penetrates the fabric, so that vibration generation starts. The amplitude and acceleration peaks are concentrated at the rise of the metal needle, and therefore, any fabric can be easily perforated in many pieces of fabric due to the large acceleration generated in the metal needle. This has effects such as being able to prevent bending and folding of the material.
