Abstract (en)

[origin: EP0734795A1] The process concerns thickness control during foil rolling, by means of characteristic curves of individual parameters (foil tension, rolling speed etc.) stored in a process computer, for various working points, and also in combination with monitor-based control. The entry-side foil thickness deviations are determined and compensated by means of in-advance thickness control. Also claimed is an appts. for implementation of the process.
