ABSTRACT:
A machine for inserting stringers into pallets includes a table assembly that establishes a horizontal working surface upon which a pallet can be placed and clamped in position. A carrier assembly that is movable in a generally horizontal plane includes an elongate trough into which a stringer can be placed. The trough carries a movable clamping rail that is adapted to clamp a stringer in the trough. The trough also carries a movable spreader bar that is adapted to spread deckboards a distance adequate to receive a stringer. The machine includes a hydraulic cylinder for reciprocating the carrier assembly toward and away from a pallet disposed on the working surface. The machine also includes a movable clamp that prevents a pallet from moving on the working surface. After a stringer has been inserted into a pallet, the spreader bar is lowered and the stringer is nailed in place. The carrier assembly then is retracted in preparation for another stringer insertion operation.
