A method and apparatus for controlling the feeding of a bandsaw blade in a horizontal bandsaw machine so that the bandsaw blade operates at a uniform optimum cutting rate. The cutting rate of the bandsaw blade is maintained constant by controlling the feeding speed of the blade into material being cut as a function of (1) the cross-sectional cut length at a time interval and (2) the feeding position of the bandsaw blade into the material.

An apparatus for detecting lateral deviations of a bandsaw blade has a follower which is in contact with and follows lateral movement of the blade. A sensing circuit, which is connected to the follower, generates deviation signals representing movement of the follower. A control circuit which is responsive to the deviation signals stops the bandsaw when the lateral movement of the blade has deviated beyond established limits.
