Abstract

A method for controlling, on a metallic coated coil being wound, the coating thickness homogeneity, the method including the following steps of A) measuring a first distance between a first reference point and a first point on the coil surface; B) measuring a second distance between a second reference point and a second point on the coil surface the first and second points on the coil being situated at different spots along the coil width; C) computing a difference between the first distance and the second distance, the difference is noted Δ12true; D) saving the difference Δ12true defining a threshold value, comparing each saved difference Δ12true to said threshold value and/or comparing a sum of differences Δ12true to the threshold value, emitting an alert when the difference Δ12true and/or the sum of differences Δ12true is higher than the threshold value.
