Rondo Ganahl AG, Frastanz, Austria, has ordered a new quality control system for its PM 2 corrugated board machine from Voith Paper Automation, Germany. The order includes a Voith LSC scanner with moisture, ash, and basis weight measurement as well as a color sensor. Also, OnQ ModuleTap actuators for control of the existing dilution water headbox are included in the automation package to attain optimal basis weight CD profiles.
The delivery additionally includes several MD controls such as multi-layer control and jet-wire ratio control. With the OnQ GradeManager, grade change time can be substantially improved with automatic grade change. Rondo Ganahl produces testliner grades (white, mottled, brown) at the mill using 100% recovered paper. The mill produces corrugated board in the basis weight range of 120-200 g/m on PM 2. With a machine speed of up to 900 m/min and a wire width of 2,720 mm, an average 300 metric tons of testliner are produced daily.
