Abstract: A plurality of pre-pressed plywood veneer assemblies are inserted one at a time onto separate trays mounted in vertically spaced apart relation on a carriage movable toward and away from a hot press, the forward movement of the assemblies on the trays being restricted by stops mounted in fixed relation to the hot press adjacent the infeed end thereof and movable between an extended position for intercepting the assemblies and a retracted position for allowing the assemblies to be moved into the hot press. Sweep arms on the rearward end of the carriage are movable into abutment with the rearward ends of the assemblies for moving them forwardly against the stops for aligning the front and rear ends of the assemblies vertically. Positioning arms mounted in fixed relation to the hot press adjacent the infeed end thereof are movable first to a squaring position for abutting the opposite sides of the assemblies for aligning their lateral sides vertically.
