Seamed press felt production expansion for Valmet


I


nvestments have been made by Valmet at its paper machine clothing factory at Tampere in Finland to


improve its capacity to produce seamed press felts for paper, board, tissue and pulp drying machines. Improvements include a new a wide weaving loom, the updating of some existing weaving looms and new fibre opening and blending machinery. The paper industry in North America and Europe is changing from endless to seamed felts, which improve occupational safety and production efficiency at mills. The installation of a seamed felt is said to be faster and requires less manpower. “This investment gives us the necessary assets to further develop our leading technology for the growing and demanding seamed felt market,” says Jari Stålhammar, vice president for


fabrics in the Services Business Line at Valmet. “It also ensures our capacity


for the coming years to deliver felts that respond to customer needs for optimized production


Road map for the future at Catexel


UK-based speciality chemicals company Catexel, whose wood pulp bleaching catalysts are used in the pulp and paper industries, has launched a new brand, website and communications approach. The move better reflects the ways in which company’s services, which enable industrial processes across a number of sectors to be faster, cleaner and safer, can be enhanced by sharing IP and technology breakthroughs. An example is when Catexel’s


R&D team identified that the chemistry used in detergents could also be used to make paint dry quicker. Catexel’s low temperature bleaching capabilities have also addressed environmental and energy saving needs. “As the paint drying example


shows, our successes in one market are intrinsically linked to what we’re achieving, in parallel, in other seemingly unconnected areas,” says Catexel chief executive Paul Smith. For wood pulp bleaching,


Catexel says the use of its catalysts may lead to a reduction of bleaching temperature and/or increased brightness development. Peroxide activation can improve the effect of the delignification and bleaching stages and enable a reduction in the use of sodium chlorate in ECF (elemental chlorine free) processes, and performance improvement in TCF (totally chlorine free) mills. Temperature reduction offers the potential for energy savings and improved fibre strength.


“The rebranding reflects the dynamism within the business and the gravitas of what we do – as a collective committed to pioneering catalysts for change,” says Smith. “The value is in the combined strength of all our entities so – structurally, operationally and visually – it made sense to bring everything together under Catexel and, in doing so, to show the true scope of our ever developing runway.” More information from www. catexel.com
