MANUFACTURING METHOD AND DEVICE OF FOAM ROLLER

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a foam roller capable of increasing the cell opening area to an area within a specified range by opening closed cells at the peripheral surface of a rubber foam body produced through the molding process of the foam roller and suppressing fluctuation of the opening area. SOLUTION: The manufacturing method for a foam roller includes a foam roller molding process to shape a cylindrical rubber foam body using a die on the periphery of a core metal, and a cell opening process to cast a TEA-CO2laser beam onto the rubber foam body peripheral surface of the molded roller so as to at least open the cell surface of the rubber foam body.
