  • Patent number: 9840054
    Abstract: 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.

  • Patent number: 5398741
    Abstract: A method and apparatus for rotary-cutting a timber to peel off a veneer by a cutting knife from the outer periphery of a timber while rotating the timber around its longitudinal axis. The timber is gripped at its two end faces by means of chucking pawls which are driven in rotation. The chucking pawls comprise a plurality of chucks which are different in radial position. The chucks grip the timber at the end faces thereof adjacent to the outer peripheral surface of the timber, and as the timber is cut by the knife and reduced in diameter so that the knife comes close to a presently outermost chuck, the outermost chuck is retracted axially away from the end face of the timber, and the next outermost chuck continues to grip the timber adjacent to the presently outer peripheral surface of the timber. For this reason, the gripping force by the chuck pawls, resisting the cutting force moment, can be made small, and the timber gripping is made reliable.
