Abstract
PURPOSE:To manufacture a rubber roll with smooth surface, having excellent mechanical strength and durability, by a method in which a rubber compound is filled in a seamless cylindrical mold in which a metal core is held and then molded and vulcanized by an induction heating method. CONSTITUTION:The metal core 4 is held inside the seamless cylindrical mold 3 whose both ends are fitted with covers having an injection port 2 and an escape port 5, and then a rubber compound is injected into the port 2 under pressure until filled up. Then, the injection port 2 and the escape port 5 are closed with blanking covers 6 and 6'. The mold 8 is moved toward the direction of arrow A while being turned and passed by a plate heating coil 7 energized with high-prequency current to generate an induced current on the surface of the mold 8, whereby the inside of the mold 8 is heated so as to uniformly and rapidly heat the whole of the mold 8 for molding and vulcanization. Thus, a flat-surfaced rubber roll having no traces of the parting line of the mold 8 and also of burr removal can be obtained.
