The plate rolling arena often places the spotlight on three- and four-roll machines. Double-pinch varieties allow operators to avoid having to remove the plate for the second prebend. Three-roll, variable-geometry machines roll thick plate to tight diameters. Four-roll machines open doors for complex forming geometries, high-production, and automation.
But what about the humble two-roll machine? For the right application, particularly those involving thin sheets, such machines can form workpiece after workpiece in quick succession. Rolling cylinders complete in a single pass, they operate in cycle times measured in seconds, not minutes.
