Rolling (metalworking)

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills near Fareham England In 1783 a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars With this new design mills were able to produce 15 times more output per day than with a hammer Although Cort was not the first to use grooved rolls he was the first to
