摘要：
A roll end (30) for a roll, in particular for a heatable roll, in a paper or board machine or in a finishing machine is made by a powder metallurgy process in a mold (20) such that a duct system (10) for a heat transfer medium is formed in connection with the manufacture of the roll end. A hot isostatic pressing process in particular is used in the manufacture.
