A rundown on rolling machines The Fabricator

They use a large-diameter, urethane-coated pinch roller that moves up with extreme pressure against a small-diameter steel top roll. A mandrel or drum, very close in OD to the desired ID of the finished part, is fitted over the top roll. Two-roll sheet rolls are extremely fast and will roll round parts even if the blank has cutouts or holes.

Fundamental concept of metal rolling mtixtl

•The friction varies from point to point along the contact arc of the roll. However it is very difficult to measure this variation in µµµµ, all theory of rolling are forced to assume a constant coefficient of friction . •For cold-rolling with lubricants, µµµµ~ 0.05 –0.10. •For hot-rolling,µµµµ~ 0.2 up to sticky condition.

Rolling (metalworking) Wikipedia

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham in Hampshire, 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
