。(Problem U to be solved by the invention) However, in the conventional example, with a backing material laminated on the back side of a skin material a made of a non-woven fabric, after heating, this skin material a and the backing material are lowered. In order to set it in mold e and pressurize it by lowering the upper mold f, the upper mold f is required, which makes it impossible to reduce production costs, and when heat-resistant, the backing material shrinks due to heat. There was a problem in that the trunk to which this skin member was attached was deformed.

にしたことを特徴とする。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a heat-shrinkable backing material stretched during extrusion on the back side of a skin material having cross on the surface side and having elasticity. are pasted together, the skin material and backing material are pressed against the mold on the cross side of the skin material, and then the backing material is heated by a heating means,
This backing material is characterized by being heat-shrinked and molded into a mold shape.
（作用）
従来の製造方法に用いた型装置の上型が不要になって、
生産コストを低減させることができる。(Function) The upper mold of the mold device used in the conventional manufacturing method is no longer required,
Production costs can be reduced.
また、表皮材は、そのクロス側が型に当てられるために
、バッキング材が急には冷却せず、このために、バッキ
ング材に均一な収縮が生じて製品の品質を向上させるこ
とができる。Further, since the cross side of the skin material is applied to the mold, the backing material does not cool down suddenly, and therefore uniform shrinkage occurs in the backing material, improving the quality of the product.
（実施例） 以下、本発明を図面に基づいて説明する。(Example) Hereinafter, the present invention will be explained based on the drawings.
第１図は本発明に係わる表皮部材の製造方法の一工程を
示しており、表皮材１は編物等の伸縮性を有する物であ
って、その表面にクロス２を有する。FIG. 1 shows one step of the method for manufacturing a skin member according to the present invention, in which the skin material 1 is a stretchable material such as a knitted fabric, and has a cloth 2 on its surface.
バッキング材３は、熱収縮性の合成樹脂フィルムであり
、例えば、ポリエチレン、ポリプロピレンを材料にして
いる。The backing material 3 is a heat-shrinkable synthetic resin film made of, for example, polyethylene or polypropylene.
型４としては、木型、パネル型、樹脂型が使用される。As the mold 4, a wooden mold, a panel mold, or a resin mold is used.
この型４は、例えばトランクの外郭形状をなしている。This mold 4 has, for example, the outline shape of a trunk.
表皮材ｌは、その表面のクロス２を型４側に向けてその
裏側にバッキング材３を張り合わせ、四方をクランパー
５によって把持する。The skin material 1 is pasted with a backing material 3 on the back side with the cloth 2 on its surface facing the mold 4 side, and is gripped on all sides by clampers 5.
次に、表皮１材及びバッキング材３を四方向に延伸させ
ながら表皮材１のクロス２側で型４に押し付け、バッキ
ング材３を赤外線照射などの加熱手段により加熱（加熱
条件＝１１０°ＣＸ ２０ｓｅｃ 、収縮率２０％）し
て、このバッキング材３を熱収縮させ、型４の形状、例
えばトランクの外郭形状に忠実な形状に成形する。Next, while stretching the skin 1 material and the backing material 3 in four directions, the cross 2 side of the skin material 1 is pressed against the mold 4, and the backing material 3 is heated by heating means such as infrared irradiation (heating conditions = 110°C x 20 seconds) , a shrinkage rate of 20%), the backing material 3 is heat-shrinked and molded into a shape that is faithful to the shape of the mold 4, for example, the outer shape of the trunk.
また、表皮材１は、そのクロス２側が型４に当てられる
ために、バッキング材３が急には冷却せず、このために
、バッキング材３は均一な収縮が生じて製品の品質が向
上する。In addition, since the cloth 2 side of the skin material 1 is applied to the mold 4, the backing material 3 does not cool down suddenly, and as a result, the backing material 3 shrinks uniformly, improving the quality of the product. .

る。(Effects of the Invention) As explained above, the present invention has a cloth on the surface side and a stretchable skin material, and a heat-shrinkable backing material stretched during extrusion is laminated on the back side of the skin material and the skin material and After the backing material was pressed against the mold on the cross side of the skin material, the backing material was heated by a heating means to cause the backing material to shrink and form into the mold shape, so it could not be used in the conventional manufacturing method. The upper mold of the molding device is no longer necessary, and production costs can be reduced. Further, since the cross side of the skin material is applied to the mold, the backing material does not cool down suddenly, and therefore uniform shrinkage occurs in the backing material, improving the quality of the product.
