Abstract
A radiator hose is provided with an inner tube rubber and a cover rubber. The inner tube rubber is coiled on the outer circumference with filament yarns made of nylon 6,6 separating predetermined spaces each other. The filament yarns are twisted at predetermined twist number before coiling, and pass through an adhesive agent supplying step, a dry-heating step while applying tension to the filament yarns and reel-hank steps, and goes into a wet-heating step. For the wet-heating step, the filament yarns are given temperature equivalent to a vulcanizing temperature, applying no tension to the filament yarns. By the wet- and dry-heating, the filament yarns are prevented from biting into the inner tube rubber. Since the filament yarns are immersed into the solution of an adhesive agent before the dry-heating, the solution attached on the filament yarns is dried off rapidly by the dry-heating thereafter.
