Abstract

PURPOSE: To obtain a bent rubber pipe having no exfoliatable inner tube with superior pressure-proof and reduced pressure-proof characteristic by a method wherein a belt-like body having a rope-shaped core embedded therein is helically wound to form a cylinder, the cylinder is fitted over a bent pipe forming mandrel and cured.
CONSTITUTION: Rope-like core member 1b made of thermo-setting polymer or hard compound rubber is injected simultaneously into a wall of the belt-like body 1a made of hard compound rubber. Just after that, the belt-like body 1a is helically wound, the lateral ends of the belt are connected adhesively to form a cylinder of non-linked condition, then the cylinder is cut into a desired length, a curved pipe molding mandrel having mold releasing treatment on its surface is fitted over the cylinder, and they are cured by a linking means such as heating treatment etc.
