A machine for producing a sheet, e.g., paper or cardboard, in which the machine may include a plurality of rolls having a bearing pin located at each end and a bearing device retaining each bearing pin. The bearing device may be utilized to guide the bearing pin on all sides, enabling a base of the bearing device to be arbitrary positioned at an angle 0.degree.&lt;.alpha.&lt;90.degree. with respect to a horizontal reference, e.g., the ground or a base surface. The plurality of rolls may include dryer cylinders and/or sheet guide rolls.

Machine for producing a sheet

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.

Heated roll bearing system

An exchange device for replacing an old transport belt in, e.g., a dryer section of a machine producing a web, e.g., paper or cardboard. The device may include a spooler for simultaneously removing the old transport belt and inserting new transport belt. The exchange device may also include a mobile carrier device that supports the spooler and may guide the spooler to an exchange location within the web production machine.
