In the Lean philosophy, we know that it is important to adapt production to the customer requests and that retooling on a line needs to be completed in minutes, not hours.

For roll forming, the set-up time of a line was traditionally a very time-consuming operation, in which rollers were changed one by one at each station (and had to be positioned accurately and adjusted individually). For some machines, this could literally take days and require highly skilled engineers.

Can any company afford this kind of downtime nowadays?
