    • A three-dimensional structure, and a method and device for producing the structure, where the structure has pressure resistant characteristics despite its voluminous and elastic nature and has higher resistance to surface wear and mechanical dimensional stability than a foamed polyethylene sheet. The three-dimensional structure is characterized in that a resin sheet has needle-like projections on its both faces, each projection has a height (H) of 3 mm or more, the height (H) and a width (W) of the projection at the height of H/2 has a relationship of H ≥ 2.5 W, the projection has a hole in its top, and the projections are joined to a sheet-like object at their tops. The method of producing the three-dimensional structure is characterized in that a large number of needle-like dies are integrated with a base plate, and a pair of base plates are arranged so as to be opposed to each other, and a resin sheet is deformed when the pair of the base plates move parallel to each other so as to intrude into the resin sheet. Further, a method of continuously producing the three-dimensional structure is provided.
    • 三维结构,以及用于制造该结构的方法和装置,其结构具有耐压特性,尽管其体积大且弹性,并且比发泡聚乙烯片具有更高的耐表面磨损和机械尺寸稳定性。 三维结构的特征在于,树脂片的两面具有针状突起,每个突起的高度(H)为3mm以上,突起的高度(H)和宽度(W) 在H / 2的高度处具有H≥2.5W的关系,突起在其顶部具有孔,并且突起在其顶部与片状物接合。 三维结构体的制造方法的特征在于,将大量的针状模具与基板一体化,并且一对基板以相互对置的方式配置,树脂片为 当一对基板彼此平行地移动以侵入树脂片时变形。 此外,提供连续制造三维结构的方法。
