A liquid mixture containing a liquid polymeric material and a granular filler is injected into a mold for centrifugal molding and subjected to centrifugal molding, thereby preparing a cylindrical body including a homogeneous dispersion layer having the filler homogeneously dispersed in the polymeric material and a high-density packed bed, formed on the outer peripheral surface side or on the inner peripheral suface side of the homogeneous dispersion layer, containing the aforementioned polymeric material more densely filled with the aforementioned filler. The high-density packed bed is removed for exposing the surface of the homogenious dispersion layer. According to this structure, the yield of the elastic cylindrical body can be improved.
Selon l'invention, un mélange liquide d'un matériau polymère liquide et d'une charge granulaire est injecté dans un moule (1) pour moulage par centrifugation, et un corps cylindrique est moulé par centrifugation. Ledit corps cylindrique est composé d'une couche de dispersion homogène (2) dans laquelle la charge est dispersée de manière homogène dans le matériau polymère, et d'une couche de charge haute densité (1) située sur la surface intérieure ou extérieure de la couche de dispersion homogène (2), le matériau polymère étant rempli de la charge à une densité supérieure. La couche de charge haute densité (1) est retirée de manière à exposer la surface de la couche de dispersion homogène (2). Ainsi, le rendement du corps cylindrique élastique est amélioré.
