Koenig & Bauer – Sauer Walzenfabriken service partnership

Cost-effective and reliable

After around six years of production, a number of the parts typically subject to wear on the Koenig & Bauer Commander CT at Badisches Druckhaus are soon due for overhaul or replacement. This specifically concerns the roller locks and the inking and dampening rollers. As the intervals for recoating the rollers and overhauling the roller locks are very similar, technical manager Ewald Adler decided to have this work performed systematically and preventively on all three towers.

In eight stages that will extend over a period of several months, a total of 336 roller locks will be overhauled and 144 rollers will be recoated. To complete this work, Koenig & Bauer is providing a ‘kick-off package’ with replacement roller locks and inking/dampening rollers for three printing units on a loan basis. When the project is completed, the last three sets of roller locks and rollers removed from the press will be returned to Koenig & Bauer. The management at Badisches Druckhaus has appointed press manufacturer Koenig & Bauer to act as general contractor for the project. Key subcontractors are the companies Sauer Walzenfabriken GmbH and S.E.M. Servicegesellschaft für Elektrik und Mechanik mbH. Sauer will be making successive deliveries of 144 inking and dampening rollers for this project, while S.E.M. will assume responsibility for proper roller fitting and adjustment. In this way, Koenig & Bauer and Badisches Druckhaus are continuing a time-tested partnership with the Sauer and S.E.M companies. Both subcontractors have already performed similar work on other presses on multiple occasions – most recently on the four printing towers of a Commander CL at Westfalen-Druck GmbH in Bielefeld. The work in Baden-Baden is likely to continue through to September, as it can only be scheduled for production-free periods. Using a tried-and-tested logistics plan as a basis, Sauer and S.E.M. will be coordinating closely with both the press user and Koenig & Bauer to complete the overhaul on three printing units at a time within a previously defined period. At each of these stages, the roller locks will be renewed and three sets of new rollers (three ink forme rollers, one ink transfer roller and two dampening rollers) will be supplied by Sauer and then exchanged and adjusted by S.E.M. Finally, Sauer will perform the removal of the worn rollers, the cores of which are then to be recoated ready for the next project. The technical manager at Badisches Druckhaus, Ewald Adler, explained the decision to award the contracts to Sauer, S.E.M. and Koenig & Bauer by emphasising their good reputation in the industry, the cost-effectiveness of the proposed approach, and their reliability as project partners.
