Prevent Cardboard Defects
At the start and end of the corrugated board production process, the moisture and temperature of the paper must remain the same and must not undergo significant changes. This is essential to prevent stress on the board and achieve a high-quality product. Since moisture and temperature parameters directly affect one another, Nebula was designed to keep them under control.
Nebula prevents cardboard defects — warping, waviness, cracking and poor bonding. The engineered moisture application ensures more homogeneous heating and adhesive penetration while reducing starch consumption. Precisely optimizing humidity levels can lead to a reduction in the required amount of starch of up to 20%.

System Components
Nebula Moisturizer
Air and heated water spray jets that prevent the cardboard from over-drying during the heating process; a modular system adjustable across a relative humidity range of 6–14%.
Nebula Scanner
High-precision humidity and temperature sensor that measures data in both transverse and longitudinal directions with an 'S' motion; a fixed version is also available.
Nebula Warp Scanner
Detects potential cardboard warping and reports it to the control panel.
Nebula Control Panel
The central panel where all necessary system parameter adjustments are made and reports are reviewed.
Closed-Loop Operating Principle
Operating within a dynamic closed-loop system, Nebula intervenes based on data from the Moisturizer, Scanner and Warp Scanner to bring moisture and temperature levels to the desired target set points.
