とにより製造されている。In recent years, rubber rolls having FRP as a core material have been proposed. A rubber roll using FRP as a core material is lighter than a metal cylinder even with the same size, and can be designed to have higher bending rigidity than a rubber roll using a metal core. Furthermore, the rigidity of the cylinder is high, so cutting and grinding in roll forming Since the deflection in the processing step is small, it is possible to obtain a roll with higher accuracy than the conventional rubber roll. The rubber roll having FRP as the core material is wound with unvulcanized rubber around the core material as in the case of the conventional rubber roller having the core material as the core material, and then the heater of the steam atmosphere or the pressurized hot water heater. It is manufactured by carrying out vulcanization at a temperature of 110 ° C. to 180 ° C.

ることがあった。However, when manufacturing a rubber roll using FRP as a core material, the core material may be deformed or cracked inside under the same conditions as when manufacturing a rubber roll using a metal core material. Due to the deformation of the roll core material, the dimensional accuracy improved by grinding etc. before vulcanization declines, and the mechanical properties of the roll deteriorate due to the occurrence of cracks inside. There were some unfavorable effects on the market.
