METHOD FOR MANUFACTURING ROLLER INCORPORATING METALLIC CORE BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a roller incorporating a metallic core body by which it is possible to manufacture a long and high quality level roller incorporating a metallic core body even when a pipe containing a resin with a low coefficient of linear thermal expansion is used so that the inside dia. is enlarged by heat. SOLUTION: This method for manufacturing the roller incorporating a metallic core body is to insert the barlike metallic core body 4 into a resin pipe 1 while induction-heating the core body 4 using a high frequency in such a manner that the outer peripheral face of the core body 4 comes into contact with the inner peripheral face of the pipe 1.
