Abstract: This invention relates to a novel method and apparatus for producing cold finished bar flats with improved bright surface condition. The bar flats are produced by a rolled method in a continuous economical process. A strip is fed to a shaving apparatus for removing burrs formed during slitting. Cold finishing rollers perform cold reduction of the strip to a predetermined thickness. Edge conditioning rollers smooth the edges of the strip and size the strip to a predetermined width. Preferably, the edge conditioning rollers alternate with the cold reduction rollers.
