ABSTRACT:
Both fully automated and semi-automated methods and apparatus are described for producing armored rod saws by progressively coating a rod or wire substrate with a slurry of a flux paste adhesive and brazing metal powders, overcoating the latter with abrasive particles, followed by fusion of the brazing metal coating thence cooling same to solidify the brazing metal into a thin layer bonded to said substrate and partially embedding said abrasive particles therein with said particles projecting therefrom to provide a myriad of sharp cutting edges.
