Chipped nail welded wire nailing strip and method

摘要

A nail having a shank formed with at least one shallow chipped recess, so as to provide nail recesses of a precise predetermined depth, and a strip of such recessed nails, in which wires are welded to the nails in respective chipped recesses. Two or more such recesses may be formed in each nail.PPThe nails may either be arranged in a diagonally staggered fashion with their heads overlapping, or may be spaced further apart so that they are parallel, with their heads aligned, but in which the heads do not overlap.PPAlso disclosed is apparatus for forming a strip of nails having recesses, and having at least two spaced apart rotary chipping tools, operable to form spaced apart recesses in the nails, at least two wire welding stations aligned with the recesses in the nails and strip wire supplies, and welders to weld the strip wires in the recesses forming the nails into a strip, and a method of forming a wire welded strip of recessed nails.
