ABSTRACT:
A back gage is provided for use with a bending brake of a type that comprises a generally flat bed and a brake edge. In use, the bending brake receives the leading edge of a sheet metal member and bends a portion of the member around the brake edge in order to form a shape therein. The back gage of the present invention broadly comprises a movable carriage assembly arranged on the bed of the bending brake, a drive assembly for moving the carriage assembly relative to the brake edge of the bending brake, and a measuring device mounted to the bed of the bending brake and coupled to the movable carriage assembly. In practice, when the leading edge of the sheet metal member engages the movable carriage assembly, the measuring device conveniently displays the distance between the leading edge of the member and the brake edge of the bending brake.
