Abstract: A profiling saw with band knife loop take-up and payoff compensation includes an endless circulating band knife which is guided around a plurality of band knife pulleys so the take-up and payoff adjustment is provided of the loop circulation path shape. The take-up and payoff system operates to move a pulley in the vertical plane for allowing the band knife to maintain its cutting orientation during movement and providing for more rapid and precision cuts into a workpiece.
