Method and apparatus for dehydrating veneer

摘要

Method and apparatus for dehydration of veneer sheet having therein a knot are disclosed. Veneer dehydration apparatus includes a first stationary single dehydrating roller (13) and a plurality of second movable sectional hydrating rollers (1A), which rollers (1A) are disposed one above the other so that a nip (L7) through which a veneer for dehydration is moved is formed between the first (13) and second rollers (1A). A stop device (8, 9, 11) determines the initial position of each second roller (1A) relative to the first roller (13) where a predetermined spaced distance (L7) is formed between the first (13) and second rollers (1A). An urging device yieldably urges each second roller (1A) to the initial position. The second roller (1A) is movable away from the initial position against the urging force of the urging device independently of the other second rollers (1A) by a knot present in the veneer sheet and just moving through the nip between the second roller and the first roller.
