    • A method of producing an annular foam product having a foam filler covered by a tubular skin. A core embedded in the filler includes a connecting portion and a U-shaped portion which form an annular frame. Opposite edges of each of at least one skin member are joined together to form a U-shaped skin tube surrounding the U-shaped portion, such that the joined edges are located inside of the U-shaped skin tube. A skin sheet is jointed at opposite ends to corresponding opposite ends of the U-shaped skin tube so as to surround the connecting portion, while the end portions of the skin sheet are turned outside in. The end portions of the skin sheet are then turned over to expose its nominal outside outwardly, and opposite edges of the skin sheet along the connecting portion are joined together to form a connecting skin tube which surrounds the connecting portion of the annular frame. The U-shaped skin tube and the connecting skin tube constitute the tubular skin which encloses the annular frame. A foamable material is injected into the cavity formed between the tubular skin and the annular frame.
    • 一种制造具有由管状皮肤覆盖的泡沫填料的环形泡沫产品的方法。 嵌入在填料中的芯包括形成环形框架的连接部分和U形部分。 至少一个皮肤构件中的每一个的相对边缘连接在一起以形成围绕U形部分的U形外皮管,使得接合的边缘位于U形皮肤管的内部。 皮肤片在U形皮肤管的相对端部的相对端处被接合,以围绕连接部分,同时将皮肤片的端部转向外侧。然后将皮肤片的端部转动 使其外侧的标称外露露出,并且沿着连接部分将皮肤片的相对边缘连接在一起,以形成围绕环形框架的连接部分的连接皮肤管。 U型皮肤管和连接皮肤管构成包围环形框架的管状皮肤。 将可发泡材料注入形成在管状皮肤和环形框架之间的空腔中。
