Cross-Direction Profile

Adjustment Feedback

Actuators located across the entire width of the machinery correct deviations in real time. Maintaining a flat cross-direction profile ensures that subsequent converting steps like printing or laminating receive a uniform substrate. If the thickness spikes in one narrow band, the resulting ridge in the roll causes localized tension spikes during unwinding.

Scanning heads glide across the web and send high frequency data to the headbox for immediate flow correction.

Performance Limit

Operators focus on minimizing the range between the highest and lowest points found in the scan. A stable cross-direction profile reduces internal stresses that otherwise cause the sheet to curl or twist when exposed to printing heat. When the distribution becomes uneven, printers find it harder to achieve precise color registration across the entire width of the press.

Proper calibration of the slice lip serves as the primary tool for leveling these discrepancies before the sheet solidifies.
