Voith has launched its new fibre orientation measurement and control product family – OnQuality – to help paper manufacturers control the fibre orientation angle.

The new solution includes the OnQ Fiber Orientation Sensor, which continuously measures fibre orientation in real-time; the OnQ Profilmatic fibre orientation control system; and the OnQ ModuleStep and OnQ ModuleJet actuators.

The integration of the quality control system is applicable for existing plants worldwide and independent of the manufacturer with little effort.

The OnQ Fiber Orientation Sensor uses high-resolution macro photography, digital image processing and nanosecond flash illumination to distinguish the individual fibres and their orientation in the moving paper web. Surface measurement is possible on both one and two sides. The OnQ Profilmatic CD control system derives suitable set points of the OnQ ModuleStep actuators from the measured fibre orientation angles, which enable zonal, mechanical profiling of the headbox slice lip using stepper motors. In combination with the OnQ ModuleJet actuators, the dilution water can also be controlled, thus avoiding undesirable side effects on the basis weight.

Voith’s OnQuality 4.0 is an intelligent and integrated concept that enables manufacturers to gain control over production processes and product quality. A broad portfolio of scanners and sensors ensures continuous measurement of various quality parameters. The apps of the cloud platform OnCumulus provide a wide range of analysis, reporting and visualization functions that are available at any time via different end devices and optimally complement the fibre orientation solution. In addition, the paper technology experts at Voith’s OnPerformance.Lab provide support to further increase the efficiency and productivity of the plants with the help of remote consulting and optimization.
