Abstract
A roll for treating a web of material includes a hollow roll supported for rotation about a stationary cross piece. Between the inside circumference of the hollow roll and the cross piece, a longitudinal chamber filled with temperature-controlled pressure liquid is provided, in which a lengthwise subdivision is arranged so that the flow of the pressure liquid in the two partial longitudinal chambers is in opposite directions in order to obtain a uniform temperature distribution along the roll.
