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 segmented anvil roller and a scribing roll. The segments of the anvil roll are arranged side by side along an arbor. The arbor carries inflatable bladder ribs along the length of the arbor to provide uniform contact pressure to the strip during scribing at the opposite side of the strip by the scribing roll.
