7 8 14 VariTop winders. Afterwards, the slit rolls are transported to an automatic weighing device and labeling unit and finally to the Twister 2 Line roll wrapping system. The finished wrapped rolls are then sent with the help of chain conveyors over a connecting bridge from the PM building into the finished goods warehouse. As part of the Process Line Package, LEIPA received a production line, that not only included the complete automation solution and the machine clothing but Fig. 7: Reel section with Janus MK 2 and Sirius wind-up system. Fig. 8: VariTop winder. Fig. 9: Roll wrapping station Twister 2 Line. 19/05 also had these components optimally matched to the paper machine in preliminary trials. For a trouble-free startup curve, forming fabrics, press sleeves, press felts and dryer fabrics from Voith Fabrics were used as initial machine clothing. The extensive Voith Automation solution includes the process, quality control and information system and extends from the preparation of the raw material to the finished end product. The web browser makes all current and historical machine, process and quality data mill-wide available in the information system. This facilitates easy access to data for the planning of optimization work and for trouble-shooting. The automation system was subjected to extensive functional tests in „Factory Acceptance Tests“ at Voith so 9 that a tested and pre-optimized system could be successfully installed. Ahead of time Project handling with the Process Line Package, proven technology based on the One Platform Concept as well as a successful system partnership have proven very successful at LEIPA. Since production commenced as early as four weeks ahead of the agreed date, the further optimization phase also went off very successfully. The intermediate trial 1 was brought forward by 7 weeks and intermediate trial 2 even by 6.5 months: on October 13 the two trials were successfully completed together.
1 Olaf Specht Voith Fabrics olaf.specht@voith.com Fig. 1: LEIPA-Schwedt PM 4 – the world’s most modern LWC paper machine. Four: the winning number! Successful start-up of the world’s most modern LWC paper machine with Voith Fabrics From beginning to end of this gigantic project, 4 was the magic number. On July 4, 2004 LEIPA’s PM 4 started up without a hitch, thanks to 4 decisive factors: the Leipa, Voith Paper and Voith Fabrics teams, plus a brilliant idea. The idea of building an LWC paper machine using up to 100% recovered paper – a world premiere. For Voith, the start-up actually began 18 months earlier, with extensive research to check the feasibility of this machine concept. The Voith Paper VPM 4 test machine in Heidenheim was converted accordingly, and Voith Fabrics adapted the machine clothing in all three sections to the new requirements. 15 From test machine to print shop The quality of the paper produced on VPM 4 was repeatedly checked using the latest analysis equipment. Towards the end of the preliminary project phase, paper samples were sent for printing and afterwards analyzed in the laboratory for print- 19/05
