A method and apparatus for operating a dryer used to reduce the moisture content of sheet material. A drying chamber is provided and includes a plurality of drying sections and a single point exhaust system. A seal section located at the input end of the dryer includes an exhaust passage through which a gas sample is drawn by a sampling fan. Gases within the seal section are a combination of ambient air drawn through restricted passages at the entry to the seal section and exhaust gas that bleeds into the seal section from the drying chamber. A controller monitors the temperature of the sampled gases and ambient air and adjusts the rate of exhaust flow from the main exhaust system as a function of the temperature differential. A heating system is also provided for heating the seal exhaust gases above the pitch condensation temperature for the flow.

A large number of green veneers for plywood respectively having high water contents and formed in a rectangular shape are vertically laminated to obtain a veneer laminate having a quadrangular prismatic shape. The veneer laminate is located between upper and lower platen members so that two opposite side faces of the veneer laminate vertically form cut face gathering planes. The upper and lower platen members are moved toward each other to apply a pressing force to the veneer laminate. The pressing force applied to the veneer laminate is released or weakened while the water drawn through the cut face gathering planes by the pressing force is dripping downward along the cut face gathering planes of the veneer laminate vertically formed.
