ABSTRACT:
A forming apparatus for shaping a workpiece made from malleable metal strip driven through the apparatus comprises a main frame on which are mounted driven bottom rollers for driving and supporting the workpiece through the apparatus and top rollers pressing the strip against the bottom rollers. The top rollers are mounted on side sub-frames which are traversible towards and away from the longitudinal center-line of the apparatus and which carry forming tools. The subframe may carry forming rollers mounted in cylindrical carriers which are themselves rotatably mounted end to end in support tubes extending parallel to said center-line and are rotationally adjustable independently of each other, for example to allow the amount of angular deformation of the strip to be adjusted without necessarily changing the forming tools. Bars provided to effect bending may be readily adjusted for size variation.
