Abstract

A peripherally drilled roll for the heat treatment of web material, includes a roll body having axially parallel drilled passages disposed just beneath its surface for guiding a heat-carrying fluid, at least one flange pin bolted to the front end of said roll body having a central bore, supply and discharge passages for the heat-carrying fluid in the flange pin, and connecting passages in the flange pin for the axially parallel drilled passages, wherein the supply and discharge passages are formed as blind holes meeting in the flange pin and produce the flow connection between the central bore and the front end ports of the axially parallel drilled passages, and the connecting passages of the axially parallel drilled passages are configured in the flange pin as blind holes meeting therein.
