Abstract
Abstract Method and product made for preventing loose tinkles in a wire mesh product. Opposite ends of a sock of knitted wire mesh are subjected to a single-ply bonding operation such as electric resistance welding, thereby bonding the tinkles to the mesh. The sock is then compressed to produce a foraminous product suitable for use as a slag filter in automotive airbag assemblies.
