ABSTRACT:
An apparatus for building pallets comprises a jig frame adapted to maintain a plurality of deck boards in deck board locations on top of a plurality of stringers in parallel stringer locations. A gantry frame is mounted above the jig frame and a plurality of nailing guns is mounted on the gantry frame. The gantry frame is movable with respect to the jig frame to position and operate the nailing guns to nail deck boards to stringers. The nailing guns are mounted to the gantry frame such that they can move up and down with respect to the gantry frame, and the nailing guns are biased toward a lowest gun position. Each gun can move vertically so that when using uneven boards, all guns will fire.
