Boosting runnability deep in the heart of the reel
Wider, faster, and ever more complex: printing presses are under continuous development. Which - among other things - makes reelstand and core design equally ever more demanding.
Runnability issues grow with longer print runs, subjecting especially newspaper printing to setbacks in cost-effectiveness and profitability. For runnability, in turn, perfect unwinding from the reel is of the essence.
Here, core design comes into play. Quite numerous are the reasons why a reel might not run perfectly round, thereby splitting and causing breaks. In close collaboration with Corenso, a world leader in specialized core and coreboard technology, our R&D and Technical Customer Service conducts extensive testing and analyzing core performance.
What’s so challenging about core design? Reel cores not only have to withstand enormous pressure, but most complex and ever changing combinations of interacting forces - axial pressure, dynamic radial pressure, bending, torque, chuck penetration, and vibrational stress at high rotational frequencies, to name the most important.
Developing cores for newsprint reels that are able to withstand the immense forces occurring in, e. g., 2 m wide presses at speeds of 15 m/s, is a new task as challenging as it is intriguing. But with our joint research projects and extensive expertise, solutions are already in the making.
