A pallet is automatically assembled and nailed together on a horizontally reciprocating carrier. The carrier moves in a forward direction beneath a slat dispenser. A first series of one-way trip dogs mounted on the carrier successively removes the bottom slat from a stack of slats held by a dispenser to deposit a series of slats onto the carrier to form the bottom deck of a pallet. The carrier has stringer engagement levers which engage the ends of a series of stringers held in dispensers. The carrier reverses direction after deposit of the bottom series of slats and each stringer engagement lever pulls a stringer from the dispenser with each stringer positioned transversely to the previously dispensed slats. As the carriage moves in the reverse direction, another series of one-way trip dogs mounted on the carrier successively dispenses a second series of slats to form the top deck of the pallet. The carrier with the laid-up pallet next moves to a nailing station where nailers automatically fasten the top and bottom slats to the stringers. The carrier then moves to a ratcheted bottom-stacking device which removes a nailed pallet from the carrier and adds that pallet to the bottom of a vertical stack of pallets.
