Technical center for paper

The laboratory calenders in the technical center are based on ANDRITZ Küsters’ experience and are available to customers from all over the world to run trials with their products under actual operating conditions.

The machinery is kept up-to-date with the latest technical developments so that optimal conditions prevail. With the use of modelling tools, operational conditions of production machines can be replicated. By running trials, customers and potential customers discover what enhancements to the paper web are achieved with ANDRITZ Küsters' smoothing technologies. The dimensions of the laboratory machines are such that the smoothed papers can also be commercially printed.
