Abstract: Apparatus for pallet fabricating operates to automatically nail together an arrangement of transversely extending slats and longitudinally extending stringers, which is continuously advancing. The automatic nailing utilizes nailing control in which a slat position sensor determines that a slat and underlying stringers are in position beneath a plurality of nail guns for nailing. The arrangement of slats and stringers are continuously moved by a conveyor as the nailing takes place. The slats and stringers are positioned on the conveyor automatically by controlled ejection of the same from slat and stringer magazines.
