Optimal rolls – optimal paper quality

Deflection compensation rolls are the core of the calendering and pressing process and part of an overall system. This system is formed by the rolls themselves, a complex hydraulic system with zone control, hydraulic units and the controller. Today’s production process often demands more from this system than was envisaged at the time of its original design. Reduced or increased distributed loads, higher speeds and modern frames of reference change essential parameters in the roll system, such as the temperature balance. A well-documented analysis of the roll system gives clarity here. Current production parameters are recorded.

Range of services
• Recording of current performance data
• Investigation for increasing the performance of the system: Speed,
  distributed load, temperature
• Investigation in the case of system changes such as coating of the
  roll sleeves, additional external profiling, changes in paper technology


Customer benefits
• Presentation of the necessary measures to be taken in the hydraulic
  and roll system (pressure, temperature, cooling, flow rate)
• Well-documented analyses, arranged in a hierarchy, on planned
  performance increases and / or changes in paper technology on the
  basis of real measurements
• Concrete set/actual comparison (all influencing factors are included
  in the measurements)
• Advising and engineering by competent Voith specialists
