B MU DRYER PROCESS AND SECTION TO DRY A PAPER TEXTURE, AND APPARATUS TO OPTIMIZE THE DRYING OF A PAPER TEXTURE AND / OR ENERGY CONSUMPTION IN THE DRYER SECTION OF A PAPER MANUFACTURING MACHINE MV D A process and apparatus for drying a paper texture are exposed, in which the paper texture (W) is dried against the heated cylinder surfaces of the drying cylinders (20, 24, 24 '; 410) and by air blow drying with at least one air blow module (M ~ 0 ~, M ~ 1 ~, M ~ 2 ~; 434, 634, 734). The final moisture content of the paper texture (W) and / or its quality and / or cross-section is regulated by adjusting the drying efficiency by blowing air. To optimize drying and / or energy consumption, the paper texture from the press section can first be dried using at least one group of drying cylinders to an average dry material content of 70%, then than the texture is fed to a drying, profiling and curling control device, in which the dry material content of the paper texture is regulated to the desired level by the blowing of hot air or steam in the direction of the paper texture .
