After installation of a long nip style press in the board machine at Porstendorf, Germany, MultiFlex V3 press felts from Voith Paper were installed for start-up. The decision was thus made to introduce a clothing supplier not previously active in Porstendorf. The concept was customized. In particular, the outstanding service at start-up confirmed to the team in Porstendorf that the right decision had been made in choosing the clothing supplier. Meanwhile the new press has already been running several weeks and in summary it can be said that all technological specifications have been met or surpassed. "Especially noteworthy are the 52% dry content achieved and the width shrinkage which was reduced by more than 10%", observes plant manager Steffen Söll.
The board machine with 2.32 m net width and a speed of 80 m/min produces 40,000 tons of chipboard per year. At the turn of the years 2009/2010, the two previous reversed presses were replaced by a long nip style press for press loads up to 500 kN/m. A straight-through press was positioned at the end of the press section for setting the desired surface characteristics. The goals of the conversion were: improvement of the energy balance, reduction of production disturbances due to vaporization bubbles and improvement of ply bond strength.
The success of MultiFlex V3 is based on Voith Paper's specialty for the challenges in the press section, the well-proven Vector technology. This comprises a tri-axial non-woven base fabric structure that provides elasticity in all three spatial directions for excellent compaction resistance and self-cleaning properties. It also has high active void volume for controlled dewatering and handling large amounts of water. Even pressure distribution leads to more uniform drying whilst the multi-axial structure provides low flow resistance and maintained permeability.
