Optimizing paper and board machine CD profiles with Tapio Analysis

Graph showing excess basis weight in cross-direction (CD) paper profile leading to fiber overuse and potential savings of approximately 7800 t/a.

Optimizing paper and board machine CD profiles with Tapio Analysis In modern paper production, achieving an efficient and accurate cross-direction (CD) profile is critical for product quality and production cost control. In typical production lines, online scanners provide the operators with the CD profile. However, online QCS (Quality Control System) scanners have inherent limitations: they […]

Locate problematic machine elements using Tapio MD Analysis

Diagram showing a web passing through rolls with quality variations and geometry errors, illustrating how machine direction frequency stays at 1 Hz even as velocity and wavelength change.

Locate problematic machine elements using Tapio MD Analysis During a shutdown, several components are replaced. But how do you know which one actually caused the problem? In many cases, recurring machine-direction variation continues after maintenance, because the root cause was not correctly identified. In paper, board, and other continuous production processes where the product is […]

Hidden defects in rolls: a closer look with Tapio RQP Live

Hidden defects in rolls: a closer look with Tapio RQP Live A paper, board or plastic roll may appear perfectly fine on the outside. The surface layers may seem to be uniform, smooth, and free of any obvious defects. However, beneath the outer layers, hidden issues can exist that compromise the performance and quality of […]
