ABSTRACT OF THE DISCLOSURE The specification describers a method and an apparatus for the continuous manufacture of hollow bodies of poly- merisable synthetic resins, the method involving the placing of a fibrous substructure previously impregnated with synthetic resin on a long chuck which rotates con- tinuously; moving the said fibrous substructure, by continuous traction, along the geometric axis of said chuck; continuously rolling or winding around the sub- structure thus formed, other fibrous elements of like nature which have been previously impregnated with the same or another synthetic resin, said elements overlapping and/or superimposing one another to form a layer of the desired thickness; compressing the outer surface of said layer to eliminate possible hidden air bubbles; gauging and correcting where necessary the dimensions of the hollow body being manufactured; treating said hollow body t? achieve polymerisation, curing and hardening of the resin, and cutting the continuous hollow body thus obtained into predetermined lengths.
