Abstract (en)
[origin: EP1985385A1] A disk roll includes a shaft member and a circular ring member fitted to the outer circumference of the shaft member. The circular ring member has a circular ring shape and is fitted to the disk-shaped shaft member. The circular ring member includes a plurality of arcuate members arranged in the circumferential direction. The arcuate members are each secured to the outer circumference of the shaft member by a screw, and the circular ring member is thus fitted to the shaft member. The circular ring member is made of the plurality of arcuate members instead of being integrally molded, and therefore the manufacturing cost can be reduced. Since the circular ring member can be divided into the arcuate members, it can easily be transported and mounted to the shaft member.
