ABSTRACT:
The subject apparatus is a device constructed and adapted to bend longitudinally extending members into a desired degree of curvature so that such curved members may be used for various architectural or construction purposes. Such apparatus is comprised of a frame member having an upper platform and a lower platform, and disposed between such platform members are a plurality of parallel roller members through which roller members the longitudinal members are drawn and move for the bending process. The roller members are adjustable so as to be positioned relative to another at different positions so as to adjust the degree of curvature finally achieved as the roller members pass therethrough, and for this purpose such rollers are disposed on their respective upper and lower ends in adjustable tracks in the upper and lower platforms respectively so that the rollers can be moved to various distances and positions from one another to accommodate a desired degree of bending.
