Production increase, energy saving

Increasing the line load in the press nip leads to an increase in dry content and in the initial wet strength of the paper web. The greater paper strength reduces the frequency of breaks and increases running time efficiency.

The optimization potential of entire press sections is highlighted with the latest calculation methods and use of the most modern roll covers and clothing.

Many components of a paper machine are designed according to a manufacturer’s standard for economic reasons and thus are often oversized.

The potential of the components for increasing line load are utilized to increase productivity. In an exact examination of components during a Finite element analysis, the limiting elements are identified and suggestions for optimization are worked out. With the eyes of an experienced press specialist and knowledge of the latest technology, all required inspections are carried out. For example:

Roll design:                roll sleeve, journal, bearings, screw connection,
                                 cover, cooling, crown bow, etc.
Compression system: compression cylinders, hydraulic unit, valves,
                                 levers, etc.
Machine frame:           condition of the components (e.g., corrosion)
                                 longitudinal supports, brackets, levers,
                                 support connection, center of rotation’s orientation
Drive power:                NRL, RDC (normal running load, recommended
                                 drive capacity)


Customer benefits
• Component potentials are utilized for increasing line load
• Increase in dry content, lower frequency of breaks due to greater
  wet strength
• Speed increase or lowering of steam pressure, or energy saving
