Claim:
An apparatus for use in cutting wood and reducing saw dust accumulation on the wood, said apparatus comprising: a first continuous band which moves along a first continuous path at a first speed and which cuts the wood and creates saw dust during cutting of the wood, said first band having a straight run along which the first band moves in a first direction at the first speed during cutting of the wood, said straight run of said first band having a series of teeth which cut the wood to form saw dust and a kerf in the wood, a second continuous band which moves along a second continuous path a second speed which is less than the first speed and which removes saw dust from the kerf formed in the wood by the first band while the first band is cutting the wood, said second band having a straight run along which the second band moves in the first direction at the second speed which is less than the first speed while said straight run of said first band is moving in the first direction at the first speed and is cutting the wood, said straight run of said second band being at least partially disposed in the kerf in the wood and being effective to remove saw dust from the kerf in the wood during at least a portion of the cutting of the wood by said straight run of said first band, a first band drive which engages said first band and moves the first band along the first path at the first speed, and a second band drive which engages the second band and moves the second band along the second path at the second speed which is less than the first speed while the first band is moving along the first path at the first speed during cutting of the wood by said straight run of said first band.
