摘要
It is well known to improve the efficiency and the durability of saw blades by means of hard metal members secured to the front flank of the saw teeth so as to form the effective cutting edges and surfaces of the teeth. With the invention substantial advantages are achieved by mounting the hard metal (8) members in a more lying position on the rear flanks (12) of the teeth (6), as hereby the foremost end faces (14) of the members are used as cutting shares. It is even possible to completely avoid the teeth on the carrying saw blade (4), as the hard metal members may be laid up in suitably inclined positions and be secured to each other and to a straight edge on the carrier blade (4), such that they will form the saw teeth themselves. In the production a very simple grinding technique can be used for forming the required clearance above and aft of the active cutting edges.
