Lead bars of various height-to-width ratio have been rolled down in a model rolling mill to reductions of as great as 60 percent between rolls designated as smooth, partially rough, and rough. The results of experiments to determine the amount of spread which each bar undergoes are presented nondimensionally, and these are compared with the spread formulas of Wusatowski, Hill, and Sparling.
