ABSTRACT:
The blade track control system employs a pair of bearing pads and a pair of sensors. Each bearing pad is provided with a supply of compressed air of constant pressure to provide an aerodynamic bearing surface film against a rotating saw blade. Each bearing pad is mounted on a structure, a portion of which may be flexed in order to deflect the saw blade from a datum plane into a cutting plane. Each sensor detects a deviation in the saw blade from the cutting plane and emits a signal which effects a movement of the bearing pad toward or away from the blade in order to effect a corresponding deflection of the saw blade back to the cutting plane. The two bearing pads are mounted independently of the sensors and each is moved relative to the saw blade by deflecting a cross bar on which the bearing pad is mounted in cantilevered fashion.
