ABSTRACT:
A roller flanging apparatus for flanging a metal strip has a flanging head that comprises a pair of working idler rollers. The idler rollers have outer surfaces forming a flanging angle therebetween. The edge of the metal strip passes between the rollers in contact with the roller outer surfaces to provide a flange on the metal strip edge. The idler rollers have an axis which defines an acute angle with a line extending perpendicular to a line that indicates the direction of movement of the metal strip and the acute angle is defined in the direction of movement of the metal strip.
