The machine may include a dryer section including at least one dryer group having a plurality of dryer cylinders. Centers of a first plurality of the plurality of dryer cylinders may be arranged on an upper level and centers of a second plurality of the plurality of dryer cylinders may be arranged on a lower level spaced a distance from the upper level. A top felt may be associated with at least one of the first plurality of dryer cylinders and a bottom felt associated with at least one of the second plurality of dryer cylinders. The machine may also include a meandering run path for the material sheet through the at least one dryer group, the material sheet being guided in the meandering run path by the top and bottom felts, and at least one transition area between the plurality of dryer cylinders. The top and bottom felts may be positioned to guide the material sheet therebetween in the at least one transition area between the dryer cylinders.
