摘要： Contour machine in which a worktable is fixed, and enclosed wheels are provided for mounting a band saw, the machine being pivotable with respect to a base, and in which a rotary table, mounted on the worktable, may be automatically set into rotation in the forward or reverse direction or stopped through a curvesensing guide mechanism. The machine body is pivotable with respect to the base in a plane perpendicular to the face of the band saw, together with upper and lower housings which lodge wheels for guiding the band saw. The machine has means to provide an adjustable and reproducible relationship of the body with respect to the base, as well as means for immobilizing the pivoted machine body in various positions. In addition, with a view to attaining savings in manpower and automation of operation, units are provided for indication of the saw tension, for bringing a saw-container housing to a saw-mounting position, for clamping the saw, for adjusting the relative distance between a workpiece and a saw-blade guide mechanism, and a unit for stopping the saw movement upon completion of the machining operation.
