    • A method and apparatus (32) for making a three-dimensionally formed laminate (20) by positioning a mask (62) having an opening (64) above a flexible film (52) for rotation therewith such that a foamable liquid mixture (71) sprayed downwardly through the mask opening onto the film is distribute with the predetermined shape of the laminate to be formed. Separation of the mask (62) and the film (52) with the foamable liquid mixture (71) remaining on the film for processing during a transient state after substantial completion of expansion but before substantial curing. A flexible sheet (26) and the film (52) with the foam (71) therebetween are positioned between first and second three-dimensionally contoured mold surfaces (84,86) that are moved toward each other while the foam is in its transitory state to form the flexible sheet and provide a collapsed foam layer (28) that is bonded to the flexible sheet with the predetermined shape as the three-dimensionally formed laminate (20). A first frame (50) supports the film (52) on which the foam is distributed by the rotation on a rotatable table (44), while a second frame provided by a hoop assembly (72) supports the flexible sheet (26). A hooping station (36), a cutting station (40) for trimming foam flash, and a backing station (42) for providing a backing layer are also provided. A second mask (122) is also used to register the collapsed foam layer (28) and the mold surfaces (84,86).

    • A method for three-dimensionally shaping cover materials such as woven or knitted fabrics, vinyl, leather, and the like is performed by providing a cover material (18) and a layer of foamable liquid reaction mixture such as polyurethane which changes from liquid to a viscous state (16') at the beginning of the gas generating reaction, compressing the combined cover material and the foamed layer in a mold (21, 22) having surface configurations corresponding to desired final three-dimensional shapes with the compression being performed when the foam layer has substantially completed rising, but before substantial curing thereof takes place, and then allowing the foamed layer bonded to the cover material to proceed in curing reaction. The three-dimensional cover material shaping is performed by this method without external heat or high pressure so that the cover material can retain its original appearance and high quality. By changing locally the spacings between mold halves (21, 22), the resultant foam layer bonded to the cover material can be provided with portions having different local thicknesses and hardnesses.
    • 通过提供覆盖材料(18)和发泡液体反应混合物(例如聚氨酯)的层从液体变为液体,进行三维成形例如机织或针织织物,乙烯基,皮革等覆盖材料的方法 在气体发生反应开始时,在粘性状态(16')下,在具有对应于所需最终三维形状的表面形状的模具(21,22)中压缩组合的覆盖材料和发泡层, 泡沫层基本上完成了上升,但在其发生大量固化之前,然后允许粘合到覆盖材料上的泡沫层进行固化反应。 通过这种方法进行三维覆盖材料成形而无需外部热量或高压,使得覆盖材料能够保持其原有外观和高质量。 通过局部地改变半模(21,22)之间的间距,粘合到覆盖材料上的所得泡沫层可以设置具有不同局部厚度和硬度的部分。
