Abstract
A veneer drying apparatus comprises a pair of upper and lower hot plates connected to a heating unit and a plurality of steam escape grooves formed in the opposing press surfaces of the upper and lower hot plates. The apparatus further comprises intermittently driven endless belts and driving and driven rollers on the unloading and loading ends, respectively, of the lower hot plate. The endless belts are trained over the driving and driven rollers for transferring veneer P over the upper surface of the lower hot plate. Each endless belt has numerous apertures formed in the entire surface thereof in a regular pattern. The driving rollers have numerous protrusions formed on the periphery thereof for engaging in the apertures formed in the endless belts. The endless belts are smoothly driven by rotation of the driving rollers due to the protrusion-aperture engagement. Not driven by friction, the endless belts can be relatively thin, so that the entire apparatus can be simplified and made smaller while achieving improved transfer of heat from the belt to veneer P and permitting easy belt replacement.
