Abstract
In a double belt press, in which the steel belts are supported on the back by rollers, inherent compressive stress occurs on the side of the steel belts of a double belt press that are supported on the back by rollers, resulting in an undesirable bowl-shaped deformation of the steel belts. In order to avoid this deformation, at least the side of the steel belts which faces away from the rollers is subjected to treatment by shot blasting before being installed in the double belt press.
