ABSTRACT:
A band saw for an industrial band mill is hollow formed, preferably on both sides thereof, and substantially from edge to edge thereof. This hollow forming eliminates the need for prestressing the band saw by roll tensioning during its manufacture. When the wheels are strained up, the band saw becomes substantially flat on the wheels. Additionally, the band saw may be made thinner to reduce material costs and to result in a thinner saw cut, thereby reducing sawdust waste. Less friction between the band saw and the timber being cut reduces heat build-up, thereby improving the useful life and reliability of the band saw, and facilitating faster cutting rates for improved production efficiency. Preferably, the cutting teeth are swaged set. The band saw may be single edged or double edged and may be mounted in a band mill having either flat or crowned wheels.
