Final report on Contract No 7215-CA/310, 1 April 1996 to 30 September 2000.

Packaging steel has been developed to attain high tensile limits and fine thicknesses, which have made the correction of defects in surface evenness using flattening machines for shearing lines more and more difficult. Therefore, there is a need to obtain correct and consistent surface evenness on the product from plating lines. SOLLAC�s plating lines, equipped with flattening machines operating under standard pressure, were no longer able to guarantee the surface evenness required without major production losses. Two solutions were considered:
- A pressurised flattening machine equipped with a final multi-roller stage. The machine was developed by a machine manufacturer and is in operation on several plating lines in Europe.
- An integral, multi-roller pressurised flattening machine- new technology for a plating line.

This project was designed to test the operation of the integral multi-roller solution on two plating lines at the Basse-Indre factory site, in order to eliminate concerns regarding mechanical performance, and to confirm the machine's ability to correct surface-evenness defects.

The results confirmed that the integral, multi-roller flattening machine meets the packaging-steel requirements. The mechanical performance of the equipment proved satisfactory and the surface-evenness results obtained show a markedly lower degree of dispersion and are much more reproducible than with a standard pressurised flattening machine.
