ABSTRACT:
A stitch nailing apparatus for automatically sequentially placing transversely extending slats in predetermined spaced relationship with one another onto a plurality of longitudinally advancing stringers and for repetitively nailing each slat to the stringer in stitch nailing fashion, immediately following its placement thereon. A first conveyor, mounted on an elongated frame, advances and guides a lowermost stringer longitudinally of the elongated frame from each of a plurality of spaced stringer magazines. The plurality of advancing stringers simultaneously proceed in spaced parallel relationship to a nailing station wherein a separate nailing head is adjacent each stringer. A slat magazine, disposed between the nailing heads and the stringer magazines, holds a vertical stack of slats. A slat conveyor advances the lowermost slat from the slat magazine to a position transversely overlying the stringers at the nailing station. Electromechanical control means are provided for sequentially actuating the first and the slat conveyors and the nailing heads to drive nails through the positioned slat and into each stringer, and for thereafter coordinating alternate movement of the first conveyor with actuation of the nailing heads to drive additional nails in stitch fashion through the slat and into each of the stringers. The electromechanical control means automatically senses the completed nailing of a slat to the stringers, and repeats the cycle sequentially by advancing the stringers a predetermined longitudinal distance by positioning another slat overlying the stringers and by stitch nailing the slat to the stringers. The cycle is continuously repeated or interrupted in response to the control means. The apparatus readily adjusts to accomodate stringers and slats of varied dimensions and to assemble such stringer and slat assemblies of varied shapes and configurations.
