ABSTRACT:
The present invention relates to a roller for the thermomechanical treatment of a web-shaped medium, the roller including: a roller body; axial bores for a thermal treatment fluid which are incorporated in roller body near to an outer surface of the roller body and into which the thermal treatment fluid flows on an inflow side; inflow zones, formed on the inflow side in the upstream ends of the bores or in feed channels through which the thermal treatment fluid flows into the bores; and directing or guiding portions provided in the inflow zones, which transfer a rotational movement of the roller onto the thermal treatment fluid, the directing portions at least substantially completely transfer the rotational movement onto the thermal treatment fluid and in this way suppress a relative swirl between the bores and the thermal treatment fluid, while still in the inflow zones.
