で、この部分でも熱接着され、トリミングととも
に端末処理がなされることになる。 Then, the cutting blade 9 of the side mold 4 and the receiving groove 6 of the lower mold 2
are facing each other, the end portion 15 of the material is pressed by the cutting blade 9 and that portion escapes into the receiving groove 6.
As the cutting blade 9 further advances, the portion is narrowed into the receiving groove 6, but is finally cut. At this time, the cushioning material 14 in the skin material 12 is crushed because it has a cushioning property, and the skin 13 is crushed by the cushioning material 14 and the base material 11.
The shape is such that it wraps around the cut end surface and covers it. In addition, the base material 11 and the epidermis 13 are heated,
Since it is placed in the mold 1 and pressed by the side mold 4, this part is also thermally bonded, and the ends are trimmed and processed.
なお、上記の実施例は、第４図に図示するよう

りきれいに仕上がる。 In addition, in the above embodiment, as shown in FIG. As shown in the figure, the upper surface of the cutting blade 9 may be positioned below the upper surface of the receiving groove 6. In this case, a gap is created between the upper surface of the cutting blade 9 and the upper surface of the receiving groove 6, so the base material 11 and the skin material 12 (skin 13) enter there and are thermally bonded.
A small flange will be formed. By adopting such a structure, peeling of the skin material 12 at the end portion becomes more difficult, and the appearance becomes more beautiful.
