Abstract
The invention is directed to an apparatus to produce layers of material, such as paper, carton or cardboard, under use of at least one roll that can be heated in a controlled manner, in particular a dryer cylinder, with tubing attached to the end of the roll that supplies the energy necessary to heat up the roll. Bearings at both ends of the roll are mounted to a seating structure. One of the bearings is a freely carrying bearing and the steam supply is rigidly attached to the seating structure.
