Abstract: A method and apparatus for accomplishing controlled bending of elongate strip stock, such as window frame strip stock, for example. An elongate flexible die is utilized having a plurality of elongate die strips including an inner laminant having considerable beam strength. The die strips and the inner laminant are composed of a flexible polymer material or any other suitable flexible material which are retained in assembly about the strip stock to be bent by a plurality of closely spaced clamps. The elongate strip stock is confined by the flexible die along substantially its entire length during all phases of its bending and forming about a substrate having a bending surface of desired configuration.

Abstract: A split bending molding assembly is provided for finishing operations for buildings, such as crown molding for curved or straight walled building structures. The molding includes a plurality of molding strips which are assembled in place on the building structure to form a crown molding or other molding of desired decorative configuration, each molding strip forming a decorative surface segment. The molding strips are provided with cooperative cam surfaces enabling workmen to apply a prying force to a molding strip being installed to thus cause precision alignment of the molding strips as applied. When installed, the joints of the molding strips will intersect the decorative surface segments at an abrupt angle and will be almost invisible and only minimal surface preparation will be required to finish the molding assembly.
