    摘要： Corrugated cardboard is molded into a desired shape for use in interior trim, such as for use in lining the ceiling of an automobile. The molded corrugated cardboard is obtained by applying a hot-melt adhesive onto all or at least a portion of a side of a base layer of, for example, resin felt or non-woven fabric. The base layer is then applied to a plate-like corrugated cardboard layer such that the hot melt adhesive is between the two layers. The corrugated cardboard and base layers are then molded together. The base layer may be put on only a portion of the cardboard layer where molding is apt to cause wrinkling or rupture of the cardboard layer, or the base layer may be applied to an entire surface of the corrugated cardboard layer. Even if the corrugated cardboard wrinkles or ruptures during molding, the wrinkle or rupture is filled by lofting of the base layer which is simultaneously molded in a superimposed state on the corrugated cardboard. Thus, when a decorative skin layer is laminated to the surface of the molded article, any wrinkles or ruptures which were generated during the molding process do not appear on the surface of the finished product.

    摘要翻译： 波纹纸板被模制成用于内饰的期望的形状，例如用于衬里汽车的天花板。 通过将热熔粘合剂施加到例如树脂毡或无纺织物的基层的全部或至少一部分侧上来获得模制的瓦楞纸板。 然后将基层施加到板状瓦楞纸板层，使得热熔粘合剂在两层之间。 然后将瓦楞纸板和基层模制在一起。 基底层可以仅放置在纸板层的一部分上，其中模塑易于引起纸板层的起皱或破裂，或者可将基底层施加到瓦楞纸板层的整个表面。 即使瓦楞纸板在成型期间产生褶皱或破裂，也可以通过在瓦楞纸板上以叠加状态同时成型的基底层的放置来填充褶皱或破裂。 因此，当将装饰性表层层压到模制品的表面上时，在成型过程中产生的任何皱纹或破裂都不会出现在最终产品的表面上。

    摘要： A method for producing an interior a product comprising a corrugated cardboard base formed into a predetermined shape and a decorative skin layer laminated to one side of the cardboard base. Using a hot-press, a substantially planar cardboard base comprising a corrugated core and liners laminated to both sides of the core through thermoplastic resin films is formed into a predetermined shape by heat and pressure at a temperature high enough for remaining heat to be sufficient to melt a hot melt adhesive on the surface of the cardboard base after removal of the formed cardboard base from the hot press but not so hot as to scorch the paper of the cardboard base. The formed cardboard base is then taken out of the hot press and transferred into a cold press, thereafter a decorative skin is put on the surface of the formed cardboard base through a hot melt adhesive. The formed cardboard base and the skin layer are pressed in the cold press, allowing the adhesive to be melted by the remaining heat of the cardboard base to bond the skin layer to the formed cardboard base. While the skin layer bonds to the cardboard base, the thermoplastic resin interposed between the core of the cardboard base and each liner solidifies to fix the formed shape so as to prevent spring-back. The interior trim product can be used for the ceiling of an automobile.

    摘要： Provided is a laminated member for a novel automobile interior ceiling material which has good film formability, lightweight and high rigidity, excellent moldability on cold-pressing after preheating, no problem of wrinkles, improved shrinkage and heat resistance of a post-molding product (automobile interior ceiling material), and a small post-molding dimensional error. A laminated member (A) has a seven-layered structure including filler-containing polypropylene sheets (4 and 5) laminated on both sides of a foamed polyurethane sheet (1) with hot melt materials (adhesive layers) (2 and 3) interposed therebetween, and an adhesive layer (6) laminated to adhere an interior material (8) to an outer surface of one-sided filler-containing polypropylene sheet (4) and a backing material (7) adhered to an outer surface of the other-sided filler-containing polypropylene sheet (5).
