Levelling sheet metal consists of applying an undulatory deformation to sheet metal passing in-between rollers in a quincunx configuration. While they pass in-between the rollers, the outer areas of the two surfaces of the sheet metal are successively forcefully stretched and then greatly contracted, while the median fibre remains unstretched. The sets of support counter-rollers can be adjusted individually, which enables the leveller’s lower rollers to be deformed.
Each set of counter-rollers can be adjusted individually, either using a manual level or a gear motor unit, with this being done depending on the capacity of the machines or due to their use.
