Abstract
A rod bender includes a ram shaft, having a distal end with an arcuate rod contact surface, that is movable along a shaft path that passes between two rollers, each having a curved roller surface. Each of the rollers is positionable, in an analog manner, at a variety of positions along a respective roller path, relative to a distal position of the arcuate rod contact surface. A straight rod, positioned against the rollers so that it spans the space separating the rollers and crosses the shaft path, can be rammed with the ram shaft so that the rod is bent into an arc. The rod is bent as the movement of the ram shaft pushes the arcuate rod contact surface forward against the center of the rod, while the curved roller surfaces prevent corresponding forward movement of the lateral portions of the rod.
