Super Calendered Papers

The zone definition of the VIB AirTechPlus 6 is between 16 or 25 mm for adding an even moisture layer on fiber walls. After reeling and moisture absorption of the fibers, end of fiber wall expansion (movement) and moisture saturation, the roll can be calendered. In the off-line super calender or multinip calender (example: OptiLoad) the VIB GlossTech steamshowers with 100 or 150 mm wide zones are used to control gloss targets in both the MD and CD direction. Controlling and levelling the gloss with the calender steamshowers improves the roll hardness for improved runability and reel building. Thanks to the integrated control system, rejects from bad edges or other reeling problems can be reduced by half. |
As in the on-line concept, for the off-line process, the integration of the different applicators in one total concept is extremely important. The high speeds and the large throughput of the processes require 100% uptime and on-line hot back-ups. This means optimum efficiency for the whole paper production line to ensure fast and maximum return on the investment. Page |
