Scope of activities:

The main areas of interest and research directions:

  • paper machines, printing and converting,
  • stock preparation and web consolidation processes: forming, dewatering, pressing and drying,
  • laboratory tests of physical properties of paper, board and products made of them, and prediction of their strength properties in real operating conditions,
  • research on the impact of design and operating parameters of disc chippers on the quality of chips,
  • testing the quality of overprinting in classic and digital printing techniques,
  • testing of packaging materials for contact with food,
  • testing of printing materials,
  • processes of producing printing forms, printing and securing prints,
  • ink transfer studies in printing processes. 

 

Present activities:

We prepare concepts for the modernization of paper, printing and converting machines in order to improve the quality of produced papers and paper products and reduce energy consumption. We test the strength properties of paper, board and products made of them, and the impact of printing techniques on the quality of overprinting. We develop mathematical models to predict the mechanical properties of board and packaging made of them based on the mechanical properties of the raw materials used in their production.

We carry out experimental research on the press felts dewatering process using the air blowing method to increase the production of paper machines. We perform numerical simulations of the wood chipping process in disc chippers in order to improve the quality of wood chips. We develop research methods to verify the presence of potentially migrating compounds from packaging materials into food. We carry out experimental research and numerical simulations to improve the quality of overprinting in classic and digital printing techniques.

 

Future activities:

Based on modern research methods and the latest research results, work will be carried out on extending the existing mathematical models.
