A roller assembly for processing a substantially planar workpiece includes a first pinch rod and a second pinch rod mounted in opposition to the first pinch rod, the workpiece passing between the first pinch rod and the second pinch rod during operation. A radius rod is also mounted adjacent to the first pinch rod and the second pinch rod, the radius rod being selectively displaceable with respect to the first and second pinch rods to contact the workpiece after the workpiece has passed between the first and second pinch rods, the radius rod conferring a predetermined radius of curvature to the workpiece. The roller assembly further includes a roller mounted onto one of said first pinch rod, the second pinch rod or the radius rod, the roller being selectively positionable along one of the first pinch rod, the second pinch rod and the radius rod. |
