ABSTRACT:
An apparatus for stacking veneer sheets includes a table on which to stack veneer sheets, a pair of first and second conveyors disposed on opposite sides of the table, and a veneer carrier located above the table and movable between the conveyors. The veneer carrier comprises a right veneer holding mechanism and a left veneer holding mechanism. Each holding mechanism has a veneer holder. The right veneer holder grasps a front end portion of a veneer sheet conveyed by the first conveyor, and the veneer carrier is moved to the left to carry the sheet to a drop position from which to drop the sheet. While the sheet is thus carried, it is supported at its opposed side portions by a pair of spaced apart support bars located along the direction in which the sheet is carried. Thus, the sheet is allowed to curve downwardly at its substantial rear half while it is carried. The front end portion of the sheet is intentionally curved after the sheet has been held by the right veneer holder but before the sheet is dropped from the drop position, so that the entire sheet consequently has a uniform downward curvature before it is dropped.
