た。2. Description of the Related Art Generally, a material such as tricot cloth is used as an automobile interior material, for example, a skin material of an automobile seat. As shown in FIG. 34 is a seat cushion portion 35.
And a pipe-shaped frame that forms the seat back portion 36, a cushion member that is disposed so as to wrap the frame in the seat cushion portion 35 and the seat back portion 36,
It is constituted by a skin material 37 that covers the surface of this cushion member. Then, the skin material 37 of such an automobile seat is sewn by a sewing machine to the front surface side skin material and the back surface side skin material disposed on the back side of the front surface side skin material and made of cotton or urethane material. It was formed by.

That is, such joining by ultrasonic welding converts ultrasonic electric energy into mechanical vibration energy and supplies the mechanical vibration energy to the bonding surface while pressurizing the bonding surfaces of the plurality of heat-fusible members. Then, strong frictional heat is generated to melt the materials to be welded and weld these plural materials to be welded.

The interior material 21 for an automobile is created by cutting into an appropriate product size by the cutter 17.
Using the ultrasonic welding suturing apparatus 10 according to the present embodiment, the upper surface side skin material 20, the lower surface side skin material 22, and the cushion material 29 as sheet-like materials to be joined are sewn together to form the automobile interior material 21. In that case, first, each feed roller 1
8, the sheet-shaped materials to be joined 20, 22, 29 and the cushion material 29 are supplied toward the ultrasonic transducer 11 and the ultrasonic transducer 11 is operated via the booster 26 and the converter 27.
