型温と発泡熱により融着させる。In each of the above figures, the skin material and the wadding are adhered, but the method is to spray the adhesive material to the necessary portions with a spray. Alternatively, the adhesive is applied via a roller. Alternatively, the wadding may be frame-laminated. Alternatively, a heat-fusible film may be interposed, or a heat-fusible powder (for example, nylon) may be sprinkled on the surface of the skin material or wadding (to prevent the powder from scattering, if necessary). (May be temporarily fused),
It is fused by the mold temperature and the heat of foaming.

解しモールドとの通気性は保持される。If the urethane stock solution is injected into the wadding or directly into the skin material, it will be impregnated and hardened, so put a heat-fusible film on the urethane to prevent impregnation, or spray the above heat-fusible powder and the powder will be wadding (urethane). Fill in the bubbles to prevent or minimize the intrusion of urethane. Both the powder and the film are melted after foaming by the heat and mold temperature during urethane foaming, and the air permeability with the mold is maintained.
別の方法として高圧、高速の場合は、上記熱融解性フィ
ルム接着材、粉は使用しない。その理由は、高速発泡の
ためウレタン原料が表皮材とワディングにほとんど含浸
する前に発泡が完了するからである。Alternatively, in the case of high pressure and high speed, the above heat-meltable film adhesive and powder are not used. The reason is that the foaming is completed before the urethane material is almost impregnated into the skin material and the wadding due to the high speed foaming.
