Abstract
A method and device for producing band saw blades, particularly for the timber-processing industry. A blank band saw blade is produced from a metal band, such as a metal band that can be stored on a roll. Several metal bands are combined into a flush metal band packet which can be introduced into a saw band grinding machine. The metal bands are pressed onto a planar guide. The metal band packet is clamped and a grinding machine operates to produce a desired saw tooth profile. A pawl is introduced into a tooth profile which is ground into the metal band packet. The clamped metal band packet is then loosened and advanced with a predetermined tooth spacing.
Claims20
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.
