ABSTRACT
The first roll forming mills appeared around 1900, and the application of roll forming spread slowly in
the first half of the twentieth century.
Roll forming became more popular after World War Two when the demand for formed metal parts
increased. Owing to the high productivity of roll forming lines, and the increasing labor cost, gradually
more and more products designed for brake forming were roll formed. Although the basic structures of
the today’s roll forming mills are not much different than those used in the early years, new
improvements were introduced to extend the capacity of roll forming and to increase its efficiency.
