PROBLEM TO BE SOLVED: To provide a dewatering device of veneer turned from raw wood of a needle-leaved tree which can suitably dewater while preventing the reduction of a thickness of the veneer turned from the raw wood of the needle-leaved tree as much as possible.SOLUTION: A dewatering device compresses and dewaters veneer 4 by passing and conveying the veneer between a pair of rolls 1, 2 oppositely arranged with an interval S which is significantly smaller than a thickness T of the veneer. As the upper roll 2 out of the pair of rolls 1, 2, a grooved complex roll is used, in which a hard elastic body 2b having an appropriate thickness V and appropriate hardness is covered cylindrically on an outer circumference of a metal shaft 2a, and many grooves 3 having an appropriate width H and an appropriate depth U and connected circumferentially are formed on the elastic body 2b at an appropriate interval P with respect to an axial direction of the roll. The groove 3 is inclined in a direction intersecting the axial direction of the roll obliquely at an appropriate angle &thetas; on a half-cut cross section in a direction parallel to the axial direction of the roll. |
