Abstract
Provided are a porous media bearing for a band saw, a band saw for cutting cant and a method of cutting cant using the band saw. The band saw has a continuous loop blade supported by a drive wheel and first and second support arms having porous media bearings. A location of a blade cutting section, an angle of the blade in relation to the cant being cut, and tension on the blade can be adjusted by moving the first and second support arms.
Claims24
A saw configured to cut cant comprising at least one band saw comprising:
- a motor;
- at least one drive wheel configured to be driven by the motor;
- at least one first support arm comprising a first porous media bearing;
- at least one second support arm comprising a second porous media bearing;
- at least one first locking structure connecting the first support arm to the support, the first locking structure constructed to move the first support arm in a horizontal direction and a vertical direction when unlocked and lock the first support in a desired position;
- at least one second locking structure connecting the second support arm to the support, the second locking structure constructed to move the second support arm in the horizontal direction and the vertical direction when unlocked and lock the second support in a desired position;
- and
- at least one continuous loop band saw blade supported by the drive wheel, the first support arm and the second support arm, wherein a cutting section of the band saw blade being defined between the first and second support arms, the cutting section receives the cant which is cut by the band saw blade, the first porous media bearing having a curved surface for changing a direction of the band saw blade during use, the second porous media bearing having a curved surface for changing a direction of the band saw blade during use, the cutting section can be adjusted by moving the first and second support arms in the horizontal direction, and a tension on the band saw blade can be adjusted by moving the first and second support arms in opposing directions in the vertical direction so that the tension can be increased by moving the first and second support arms to be farther apart and the tension can be decreased by moving the first and second support arms closer together.

- and
- a computer system in communication with the first and second locking structures, the computer system being configured to independently control movements of the first and second support arms in the horizontal and vertical directions.
