ü PULPü To all positionsü Improvement life timeü PU (especially euca) up to 180 daysü Other positions > 200 days
ü TISSUEü Seam felt SMO also for tissueü Case in Swedenü 1800 m/min, 16…31 g/m2ü Easy installation, low energy,
45days on machine, repeat order
ü BOARDü Seam felt SMO for shoe pressü Case in Polandü High quality FBB for small boxesü No seam markingü Improved smoothness
ü Printing & Writingü Seam felt SMO for 3rd pressü Case in Argentinaü Fine & copy paper, brown paperü Double life time, up to 135 days
Shoe Press…?For Pulp Drying, Board, Paper and Tissue machines - SymBelt
ü Press shoe is stationary, shoepress belt and counter roll rotate
ü Oil film lubricates between Pressshoe and rotating belt
ü Shoe press gives around 4%more dryness after the presssection… which is correspondingaround 16% more production, or16% less energy consumption fordrying
