Abstract: In view of the production of saw blades, a continuous sheet metal strip first runs through a hardening surface. Subsequently, the teeth are ground by a grinder. Thereafter, the sheet metal strip is passed through a grinder comprising two parallel grinding wheels to process by the grinding wheel end sides the sides of the sheet metal strip. The outer ends of the laterally projecting teeth are worked by another grinder. After such a treatment of the sheet metal strips, saw blades are formed by cutting off individual length sections.
