    • A method of manufacturing a skin for foamed product involves the steps of: (a) not only preparing a plurality of flat skin forming pieces 2 to 5 by defining a skin 13 for covering an annular foamed body Y into a plurality of skins in radial directions and flatly developing the thus defined skins 131 to 134 while cutting apart at a single position along a circumference, and forming an opening 2a on a single skin surface out of these flat skin forming pieces; (b) overlapping adjacent flat skin forming pieces in such a manner that decorated surfaces of the skin forming pieces confront each other to thereby form a skin body 6 while joining side edges of the flat skin forming pieces 2 to 5 together; and (c) reversing the skin body 6 so that the front side thereof faces outward, joining diametrically opposite portions of both opening end edges of the skin body after such opening end edges have been pulled out of the opening 2a inside out, and pushing the joined opposite portions back through the opening 2a to thereby form an annular skin body 7 having a closed cross section with the front side thereof facing outward.
    • 制造发泡制品的皮肤的方法包括以下步骤:(a)不仅通过将环状发泡体Y形成为多个皮肤的径向的皮肤13来制备多个平的皮肤成形片2至5 并且在沿着圆周的单个位置切割分离的同时平坦地显影如此限定的外皮131至134,并且在这些平坦的皮肤成形件的单个皮肤表面上形成开口2a; (b)使相邻的平坦皮肤成形片重叠,使得皮肤成形片的装饰表面彼此面对,从而形成皮肤体6,同时将平坦的皮肤成形片2至5的侧边缘接合在一起; 和(c)使皮肤本体6反转,使得其前侧朝向外侧,在这样的开口端边缘从开口2a向外拉出之后,将皮肤体的两个开口端边缘的直径相对的部分接合在一起, 通过开口2a连接到相对部分上,从而形成具有封闭横截面的环形皮体7,其前侧面向外。
