Patent ID: 8151669

Claim:
A method for producing band saw blades for a timber-processing industry, wherein initially a blank band saw blade is produced from a metal band from a roll, from which subsequently through cutting to length and welding together, continuous saw blades are formed which can have hard metal teeth, the method including the steps of: (a) continuously unrolling a plurality of the metal bands ( 6 ) from upstream reels ( 8 ); (b) combining the metal bands ( 6 ) into a flush metal band packet ( 7 ); (c) introducing the metal band packet ( 7 ) into a saw band grinding machine ( 2 ); (d) pressing the metal bands ( 6 ) onto a planar guide ( 5 ); (e) clamping ( 40 , 44 ) the metal band packet ( 7 ) laterally to a direction of travel; (f) operating a grinding procedure to a desired saw tooth profile; (g) introducing a feed pawl ( 60 ) into a tooth profile ( 9 ) ground into the metal band packet ( 7 ); (h) loosening clamping of the metal band packet ( 7 ) and advancing with a predetermined tooth spacing while reducing a pressing of the metal band packet ( 7 ) onto the planar guide ( 5 ); and (i) repeating steps (d) to (h) until the reels on an input side are practically empty.
