ABSTRACT:
A hard metal or non-metal member can be formed or shaped to have varying amounts of curvature and tapering by passing the member through a forming channel defined by two sets of opposed, axially displaceable rollers which can be dynamically moved horizontally and vertically in a predetermined range. The rollers are controlled by a computer, a translator, and a electro-mechanical displacement system such as a servo motor. Using data input by a user or preprogrammed instructions containing displacement instruction in the computer, the computer can subsequently instruct servo motors, via a translator, to move the rollers in the available axial directions. The servo motors may include a mechanism for converting rotational movement into fine linear mechanical movement of the rollers. The timing and rate of movement, direction, and force of the roller can be controlled to form and shape the member into a specific contour of curves or tapering sides.
