An apparatus for manufacturing a discrete curved product from a feed stock includes a source of heat that is adapted to impose a focused beam of light on at least one surface of a work piece to cause the surface of the work piece to expand and thereby move in the general direction of the heat source

An apparatus for manufacturing a discrete curved product from a feed stock includes a source of heat that is adapted to impose a focused beam of light on at least one surface of a work piece to cause the surface of the work piece to expand and thereby move in the general direction of the heat source so as to impart a predetermined radius of curvature to the work piece. The apparatus is described in connection with one example where it may be employed to manufacture a curved backbone for a beam blade windshield wiper assembly from feed stock. In addition, a method of manufacturing a discrete curved product from feed stock, generally, as well as a discrete curved backbone for a beam blade windshield wiper assembly from feed stock, specifically, is also disclosed.
