Abstract: A board nailing machine, herein disclosed in the form of a pallet maker, in which the stringer or inner boards are automatically fed in spaced apart relation into a nailing station and the deck boards or outer boards are automatically fed into nailing position at said nailing station on opposite sides of the stringers and thereafter the deck boards are nailed to the stringers at said nailing station. In the specific embodiment disclosed the stringers are automatically fed from supply magazines into a nailing station wherein they are disposed in horizontal parallel spaced apart relation and the deck boards are automatically fed from supply magazine into said nailing station on opposite sides of the stringers and are disposed in upstanding substantially vertical nailing position at said nailing station, and the nailing mechanism is specifically designed to drive the nails horizontally through the deck boards into the stringers at said nailing station. Adjusting mechanisms are provided for varying the spaced relation between the stringers, the deck boards, and for varying the number of deck boards supplied, and to accommodate stringers and deck boards having varying dimensions. A method for assembling and nailing boards together also is embodied in this invention and includes the steps of automatically feeding in a programmed sequence inner boards into a nailing station and outer boards together. Also embodied in the method is maintaining the assembly of boards in upstanding substantially vertical position during the assembling and nailing steps of the method.
