Abstract

The object of the invention is an end part (2, 12; 32) for a thermo roll (1), through the forward flow passages (3, 13) of which, a heat transfer medium forward flow is arranged into the forward passages (21) of the thermo roll shell (20) and through the return flow passages (4, 14) of which, a heat transfer medium return flow is arranged from the return passages (22) of the shell (20). At least some of the forward flow passages (13a) of the end part (32) and/or at least some of the return flow passages (14a) of the end part (32) are disposed outside the end part (32) body, which comprises an axle journal (32') and a flange (32'). The end part (12) comprises connecting elements (13a, 14a) that are arranged between the forward flow/return flow passages (13, 14) and the shell (20) forward/return passages (21, 22) so that, the forward flow is, by the connecting element/elements (13a), distributed from the respective single forward flow passage (13) of the end part (12) into at least two forward passages (21) of the shell, and the return flow is, by the connecting element/elements (14a), combined of at least two of the return passages (22) of the shell into the respective single return flow passage (14) of the end part (12). Additionally, the object of the invention is a method of manufacturing an end part (2, 12; 32) for a thermo roll (1).
