Coating Machine Quality Control

A gravure coating line was producing striations on the thin aluminium web (due to film thickness variations). As the marking wavelength was independent of line speed, a resonance was diagnosed. This was traced (using a non-contacting probe) to web vibration at a specific point in the coating head. The solution designed was a simple, low cost web damper.
