Abstract
A method and apparatus are provided for refining the domain wall spacing of a grain-oriented silicon steel sheet by mechanical scribing using a solid anvil roll and a scribing roller including scribing segments arranged side by side along an arbor. The arbor carries inflatable bladder ribs along the length of the arbor to provide uniform contact pressure exerted by scribing surfaces of the strip.
