ABSTRACT:
A machine is proposed for the production of a material sheet, in particular a paper or cardboard sheet, with a dryer section which exhibits at least one double-row dryer group consisting of two rows of heated dryer cylinders, each of which has been assigned a transport belt circulating in a meandering fashion around the dryer cylinders of one row and the deflection rolls assigned to the dryer cylinders, thereby pressing the material sheet against the surface of the dryer cylinders, and having a drive mechanism consisting of at least one motor assigned to each row of dryer cylinders of a double-row dryer group, which causes a rotation of the dryer cylinders and deflection rolls as well as a circulation of the transport belts of the dryer section, in which the drive mechanism is designed such that the rotational speed of the two rows of dryer cylinders within the double-row dryer group can be regulated independently of one another.
