Abstract

PURPOSE:To continuously form long moldings without the need for large-size molds or a great capacity of heating cylinder by a method in which a thermoplastic resin bar of much the same cross section as the average cross section of a molding is heated so softening in advance and then molded by rotary endless molds. CONSTITUTION:A thermoplastic resin bar molding material 2 having much the same cross section as the average cross section of a long molding is heated in advance to a softening degree suitable for molding by means of a heating cylinder 3, and then the bar molding material 2 is further molded into a long molding 1 by turning rotary endless molds 4 and 5 whose peripheries are provided with carved patterns. Thus, the continuous molding of a long molding of a desired length can be attained without the need for large-size molds and a great capacity of heating cylinder and also without such a defect that only definite dimensions of moldings are moldable as in the conventional cases.
