Abstract

Abstract In a band saw (10) particularly adapted for cutting meat, blade scrapers (25, 26) remove debris from the band saw blade (18) and throw it laterally and forward of the blade (18) into an enclosure (40), which can be removed without the use of tools for cleaning and for disposing of the collected debris. The location of the blade scrapers (25, 26) is slaved to the location of the saw blade (18) to automatically maintain the proper relationship for most efficient debris removal without adjustment.
