するものである。(Prior Art) Interior materials for automobiles, such as door trims, are generally composed of a core material, a cushion material, and a skin material. The core material is made of hardboard or thermoplastic resin, the cushion material is made of urethane foam or nonwoven fabric, and the skin material is made of PVC, TPE (thermoplastic elastomer), etc.
When integrating the core materials, the peripheral edge of the skin material is wrapped around the back side of the core material and bonded with adhesive, and the surface portions are welded and fixed together using a high-frequency welder for integration and decoration. is common. In addition,
A high-frequency welder heats an object (dielectric) by applying a high-frequency electric field to the object between a pair of opposing electrodes.

ツト等を用いる。 Recently, raised fabrics have come to be used to impart a luxurious and soft feel to skin materials. The raised fabric is usually a raised fabric made of thermoplastic resin such as woven fabric, knitted fabric, or nonwoven fabric, a soft resin sheet or nonwoven fabric with flocked fluff, or a tufted carpet.

くなる。 By the way, when the above-mentioned high frequency welder is used to weld and fix the raised fabric as the skin material to the core material, the following drawbacks occur. That is, since the raised fabric has naps, high-frequency heating cannot be performed efficiently, and it is difficult to weld and fix the raised fabric, cushion material, and core material to each other. In addition, the nap cannot be completely removed and no decorative effect can be expected. especially,
This drawback becomes noticeable when the nap becomes 1mm or more.
It becomes virtually impossible to use a high frequency welder.

すことができる。 The above welding and fixing is done as follows.
First, as shown in FIG. 3, the naps 12 at the portions 10a, 10b, and 10c of the napping fabric 10 are folded down using the horn 20 of the ultrasonic vibrator and the jig 30. To explain in detail, the jig 30 has parts 10a, 10b, 10
It has a shape corresponding to c and has a flat surface 31. Further, the horn 20 has a flat surface 21
have. Then, place the raised fabric 10 on the jig 30 with the raised fabric 12 facing down, and place the horn 20 on the raised fabric 1.
Press it on the back side of 0. In this state, the horn 20
By applying ultrasonic vibration to the raised fabric 10 while moving it along the longitudinal direction of the jig 30, the raised fabric 12 located on the flat surface 31 of the jig 30 almost completely collapses and is welded and fixed to the base fabric 11. Along with being
The raised 12 comrades are welded to each other. In this way, the naps 12 of the parts 10a, 10b, and 10c can be folded down.

are further overlapped, and the electrode 4 of the high frequency welder
The core material 1, cushion material 3, raised fabric 10, and sheet 4 are sandwiched between 1 and 42 and subjected to high frequency heating. As a result, the core material 1, cushion material 3, raised fabric 10, and sheet 5 are welded and integrated. At this time, in the region 10a, since the naps 12 of the raised fabric 10 are completely laid down, high-frequency heating can be performed effectively, and not only between the core material 1, the cushion material 3, and the napped fabric 10, but also between the napped fabric 10. Welding is also ensured between the and the sheet. Also in the region 10b, the raised fabric 10 is welded and fixed in the same manner as in the region 10a.

効果も得られる。(Effects of the Invention) As explained above, according to the method of the present invention, ultrasonic vibration is applied to the raised fabric in advance to knock down the raised fluff, and then a high frequency welder is used to separate the folded raised portion of the raised fabric and the core material. Since they are fixed by welding, high frequency heating can be performed effectively, and integration by welding and fixing can be reliably achieved. In addition, since the raised fabric is completely collapsed at the welded and fixed part, a clear decorative effect can also be obtained.
