A machine for nailing elongated slats transversely on elongated stringers having a nailing station; a receiving station; a reversible conveyor extended between said stations; chucks on the conveyor adapted to grasp a plurality of stringers in substantially parallel relation disposed longitudinally of the upper run of the conveyor; a reversible drive for advancing the conveyor toward the nailing station in increments of stepped progression whereby corresponding spaced positions on the stringers are successively disposed in the nailing station; a mechanism for automatically placing slats transversely on the stringers at said spaced positions; a nailing mechanism for nailing the slats to the stringers at said spaced positions on the stringers at the nailing station whereby the stringers are interconnected in spaced substantially parallel relation; and a control for reversing the drive to retract the stringers and slats nailed thereon from the nailing station.
