Abstract

A band saw assembly and a blade tensioner assembly are set forth. Unlike many past devices, the band saw assembly has two blades for cutting workpieces—a first blade and a second blade—enabling bi-directional cutting actions in both forward and retract motions. The blade tensioner assembly can be employed to bring both blades of the band saw assembly to equal and proper tensioning values for use, and has a pair of actuators. Potential applications of use include metalworking, woodworking, glass and ceramic material cutting, plastics and fibrous material cutting, and food processing, among many other workpiece possibilities. The band saw assembly may prove particularly useful for high production and manufacturing plants and facilities.
