Abstract
The fastener strips are made from a band of wires which consists of a series of parallel spot-weldable metallic wires disposed side by side, contiguously and spot-welded to each other at longitudinally spaced points of the wires and arranged along lines transverse to the bands. The spot welds are produced by a laser beam swept across the band as the same is continuously moving. The band is thereafter cut and stamped to form fastener strips. The spot welds constitute frangible joints holding the fasteners together for manual handling of the strip but breaking when the fasteners are subjected to a separating force such as when used in a pneumatic nailer.
