A layered-up veneer board is formed by layering veneers up to a predetermined height such that the fiber directions of the respective veneers are alternately perpendicular to one another, and the layered-up veneer board is compressed by a compression device, to remove moisture contained in the veneers. Wood is a material in which the tensile strength in the fiber direction of the wood is higher than the tensile strength in the direction perpendicular to the fiber direction. With this layering scheme, even when stress is applied to the veneers and causes elongational deformation of these veneers as a result of compressing the layered-up veneer boards in the layering direction, elongational deformation of the veneers in the directions perpendicular to the fiber directions thereof can be reduced.

A pair of centering spindles are disposed away from cutting spindles and movably in the direction of Z or parallel with the axial center line of cutting spindles. A plurality of log center detecting means are disposed along the Z direction in relative to a log chucked by the centering spindles. A pair of holding members are mounted movably in the directions of X, Z, and Y including components orthogonally intersecting the X and Z. By way of controlling means, the centering spindle holding a log is caused to rotate at least one revolution thereby enabling the log center detecting means to determine each position of axial center which is assumed to constitute the axial centers at both end faces of the log, the virtual line passing through every positions of axial centers in Z direction is aligned with the Y, and the holding members are moved in the Z direction to hold the log, after which the chucking of log by the centering spindles are released. The holding members are moved in the X direction toward the cutting spindle, as well as in the Y direction to align every axial centers with the rotational center of cutting spindles, thus allowing the log to be chucked by the cutting spindle.

Apparatus and method for centering and feeding log

A veneer sheet and an adhesive coated sheet are placed on a piling table. Two vertically arranged conveyors each independently conveys one veneer sheet and stops at predetermined position, pressing member presses two sheets simultaneously vertically downwards onto the piling table where the sheets are placed.
