Abstract
A veneer stacking system providing the feature of consistent air suction above the multiple veneer stacks enabling reliable separation of the veneer sheets from an overhead conveyor. This consistent air suction is provided by independent air chambers for each stack. It also includes aligning belts for aligning the sheets on the overhead conveyor. An aligning belt replaces a section of one or both of the conveyor belts and is independently driven to speed up or slow down one side of the sheet to achieve the desired alignment. It also includes improved knock-off shoes activated byh cylinders connected to master cylinders in a master cylinder housing activated by a common mover piston for simultaneous knock off of veneer sheets onto the stacks.
