Paper – Quality control for paper, tissue, pulp, carton and cardboard

Measuring systems for the wet and dry area

Optimise quality and productivity!

We enjoy many years of experience in the pulp, paper, tissue, carton and cardboard industries. The required subject knowledge allows us to adapt our measuring systems individually for the quality control of the following processes:

  • Papermaking
  • Tissue Manufacturing
  • Board Manufacturing
  • Sizing
  • Remoisturizing
  • Coating
  • Impregnating
  • Calendering
  • Laminating

Manufacturers using the Mahlo measuring systems supply the industry sectors of paper, tissue, hygiene paper, carton and cardboard: 

  The following products from paper, tissue, hygiene paper, carton and cardboard use Mahlo measuring systems for inspection and monitoring::
 
  • Health / Personal Care / Hygiene
  • Printing
  • Furniture
  • Automotive
  • Flooring
  • Labelling
  • Industrial Clothing
  • Gaskets
 
   
  • Facial Tissue
  • Paper Towels
  • Fibre Mats
  • Packaging Paper
  • Book Hardcovers
  • Label Backing
 

Meet the hight quality requirements of the market

Narrow tolerances of quality and condition must be observed with the manufacturing, processing and coating of pulp, tissue, hygiene paper, carton and cardboard. Measurements for quality control must be performed both on the wet and dry ends for fast and accurate control.

Mahlo provides a flexible but extremely configurable measuring system for quality control for this purpose. It can be used both for measurement and logging as well as the control of process parameters in the production process. 

Systems are available from the fixed measuring point to traversing measuring systems for single and double-sided measurements with several synchronised scanners and sensors. Coating, grammage, moisture and film thickness as well as many different measurements for combined calculations both in the wet and dry area of the plant are measured.

Multiple synchronized scanners are available as standard for coating and laminating lines. Automated control integration is possible through our collaboration with leading process automation technology providers. Sealed and purged scanners are also available in stainless steel design. 

With the extrusion and coating of paper the profile control of transverse and linear profiles (CD Control / MD Control) is extremely important. This is mastered by the Mahlo measuring systems.

Quality control with the Qualiscan QMS

The traversing quality guidance system Qualiscan QMS can measure and control critical process parameters on the running web across the entire width of the product. We provide a large selection of measuring sensors to handle diverse tasks. 

Measurement of grammage

Measurement of grammage

We use the following sensors for grammage measurement:

  • Isotope sensors
  • X-ray sensors for reflection measurement and transmission measurement
  • Infrared sensors

Measurement of moisture

Measurement of moisture

We offer the following sensors for moisture measurement:

  • Microwave resonance sensors
  • Infrared sensors for reflection measurement and transmission measurement

Measurement of material thickness

Measurement of material thickness

We use the following sensors for thickness measurement:

  • Laser reflection measuring systems
  • White light interference sensors
