ABSTRACT:
A belt conveyor is provided to feed veneers in the arrow-marked direction in the drawing. A porous transfer belt having numerous of air holes therein is stretched around so as to run above said belt conveyor. Inside the porous transfer belt, a suction hood which has a plurality of small air passages formed in the running direction of the porous conveyor belt is installed to rotatably accommodate a damper further therewithin. The damper makes intermittent rotations to open or close the sucking section such that only a desired veneer is selectively sucked for sort-out transfer with the result that the need for piercing the veneer or defining in advance a gap between each adjacent two veneers is eliminated. Therefore, it is now possible to perform high speed sort-out operations without subjecting the veneer to damage or breakage resulting from tensile strength exerted thereon at the time of defining the gap.
