Abstract
A method and apparatus are provided for refining the domain wall spacing of a grain-oriented silicon steel strip by mechanical scribing and by employing more than one row of staggered small diameter scribing rolls arranged to scribe a different portion of the surface of the strip in a manner that the entire surface of the strip is scribed and in which each row of scribing rolls co-operate with an anvil roll to support the strip.
