Abstract

PURPOSE:To cover a core body of a steel pipe, etc. with a resin material, etc. while cheaply obtaining a strut, etc. by integrally forming discontinuous convex portions, by each mounting discontinuous concave grooves to the inwalls of through holes that movable dies and fixed dies mutually communicate. CONSTITUTION:A core body 10 of a metallic pipe, etc. is let pass through the through holes 4', 5' of movable dies 4 and fixed dies 5 from a nozzle 3 at a uniform rate under a condition that a melted resin material 11 is supplied into a chamber 2 while revolving the movable dies 4. In this case, the resin material 11 is fed to the concave grooves 6 of the fixed dies 5 only when any of each concave groove 6, 7 of the dies 5, 4 agree and communicate. Convex portions 11' corresponding to the concave grooves 6 are formed on coating resin, but the resin material is limited to cover an external circumference of the core body 10 when both grooves 6, 7 mutually disagree. Thus, a covered body provided with discontinuous convex portions 11' in the axial direction is obtained. EFFECT:Covering and the formation of convex portions can simultaneously be performed.
