Abstract

PURPOSE:To economically utilize necessary materials and to obtain a roll having excellent rolling effect by providing plural tapered roll surface respectively to both ends of a sleeve, and making the large diameter side of the tapered roll surfaces largest in outside diameter. CONSTITUTION:A roll barrel part for rolling is formed to a separate body as a sleeve 21 provided with a roll surface 19a at the center thereof and further respectively >=2 pieces of tapered roll surfaces 19b, 19b', 19b, 19b' to be formed at both ends. This sleeve 21 is externally fitted and fixed onto a roll shaft 20 into one body by shrinkage fitting or other. At this time, the outside diameter D3 on the large diameter side of the surfaces 19b, 19b' of the sleeve 21 contributing to rolling is made larger than the outside diameter D2 of the roll surface 19a actually contributing to rolling, and the largest diameter as the roll barrel part sleeve 21 is made the outside diameter D3. Hence, the thickness of a sleeve blank material 24 is confined to sufficiently small one.
