ABSTRACT:
A sheet metal forming apparatus is shown with a plurality of various size and shaped rollers. The rollers are substantially parallel with a first end being open, and a second end being rotatably anchored and extending through a stationary bearing housing. A slot is provided in each roller along its longitudinal axis for receiving metal to be bent therein. After inserting metal into the slot of one of the rollers, the roller is turned by a handle on the second end. The roller is pre-indexed to turn a predetermined amount so that the metal is bent against an adjacent roller through a fixed arc. Subsequently, the bent metal may slide off the open end of the roller. A small roller may have a supporting bar extending parallel thereto with a supporting plate on the end thereof slideably receiving the first end of the small roller for additional strength. By a small longitudinal movement of the small roller, and pivoting the small roller in the stationary bearing housing, sheet metal bent thereon may be slid off the open first end.
