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. When the assemblies have been squared on the trays by abutment of the stops and positioning arms, the stops and positioning arms are retracted and the carriage is moved forwardly with the sweep arms to move the trays and supported assemblies into the corresponding spaces between the press platens of the open hot press. The positioning arms then are moved to a stripping position for abutting the rearward ends of the assemblies in the hot press, for stripping the assemblies from the trays as the latter are withdrawn from the hot press by retraction of the carriage.
