Abstract: A machine (20) forming of pallets by affixing deck boards (52) to two or more stringers (50). The apparatus includes a base (22) defining a bed which has input and output sections. An inverter (28) is pivotally mounted to the base (22) for pivotal movement between a first position, overlying the input section, and a second position, overlying the output section. With the inverter (28) in its first position, a pallet is partially formed by affixing a plurality of deck boards (52) to first sides of two or more stringers (50) while those pallet components (50, 52) are held within fittings (56, 62, 64, 66, 68) carried by the inverter (28). Affixation is effected by a tower (86), having a plurality of nailer guns (100), moving across the inverter (28).
