The SolarPress covers were first installed at Estonian Cell in June 2010. The previously installed rubber covers had worn to such an extent that they had to be replaced after only eight months running time. The abrasion had been caused by very high line loads and wire tension.After one year’s application the SolarPress cover combination was not showing any significant abrasion and is able to be returned to operation without difficulty after a standard grinding. Currently, a second pair of SolarPress covers, which has been adapted to the requirements of Estonian Cell, is installed in the twin wire press. Supported by Estonian Cell, Voith Paper was able to optimize the crown of the roll covers during regular nip inspections so much, so that present nip conditions are considered perfect.Since April 2006 Estonian Cell produces aspen bleached pulp for the paper industry with a capacity of 140,000 tons per year.
