Abstract
A method of preparing an annular skin tube for a foam product. Tubular skins are joined together end to end, at opposite ends thereof except at least one set of unjoined ends of at least one selected pair of the adjacent tubular skins, so as to prepare an intermediate skin tube such that a nominal outside of the intermediate skin tube is exposed. An unjoined portion is provided on the outer periphery of the intermediate skin tube, adjacent to the unjoined ends. The unjoined ends are joined, while end portions including the unjoined ends are superposed on each other and are passed through the unjoined portion outwardly of the intermediate skin tube such that one of the end portions is turned inside out. The above-indicated one end portion is turned over to expose its nominal outside. Thus, the intermediate skin tube is formed into the annular skin tube.
