  • Patent number: 5123807
    Abstract: A system for stacking veneer sheets conveyed from two different directions includes a lower mechanism for carrying a first veneer sheet to a first position above a stack support and an upper mechanism for carrying a second sheet to a second position above the first position. The first veneer sheet carried to the first position may not be dropped immediately, but waits for the second veneer sheet to be dropped thereon from the second position, and then the first and second veneer sheets may be dropped as one body on the stack support. The lower carry mechanism includes a carry roller and a sheet carrier which may be moved substantially synchronously. However, the sheet carrier is moved through a stopper away from the carry roller when the veneer sheets are to be freed from the support thereof by the sheet carrier.

  • Patent number: 4897018
    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.

  • Patent number: 4486963
    Abstract: A method of drying a veneer sheet is provided. The method comprises the steps of tenderizing, compressing, and drying a veneer sheet. The compressing and drying steps are performed at the same time. The tenderizing step is preferably be performed before the above two steps but may be done thereafter or at the same time. An apparatus for performing the method is also disclosed. The apparatus comprises tenderizing means, deceleration transfer means, and heating means. The deceleration and the heating means are combined into one section. A plurality of rollers are used as deceleration transfer means.
