A veneer dryer has an entry end and an exit end. A conveyor conveys sheets of veneer through the dryer from the entry end to the exit end. A drying medium is applied to the veneer in the dryer. The conveyor includes a first plurality of drums, each having an axis of rotation and being rotatably mounted in the dryer and a pair of belts permeable by the drying medium. The belts run together around the drums. The sheets are captured for conveyance through the flow of drying medium in the dryer between the belts. The belts extend around a first drum, then in a direction generally from the exit end toward the entry end, then around a second drum whose axis of rotation is spaced toward the entry end from the axis of rotation of the first drum, then in a direction generally from the entry end toward the exit end, then around a third drum whose axis of rotation is spaced toward the exit end from the axis of rotation of the second drum, then in a direction generally from the exit end toward the entry end, then around a fourth drum whose axis of rotation is spaced toward the entry end from the axis of rotation of the third drum. Each drum has a generally right circular cylindrical outer circumferential surface. The axes of rotation of the first and second drums and the surfaces of the first and second drums are spaced so that the sheets of veneer are pressed against the surfaces of the first and second drums for greater than 180 DEG of the rotation of each of the first and second drums.
