Trelleborg's Rollers & Belts operation continues to push forward the boundaries of what can be achieved in the field of tissue converting with two upgrades to its range of polyurethane coverings for its tissue converting rollers – the new Rollin Pless Plast 4 and Press Plast 4D.
Guillaume Bordais, sales and business development manager for Rollers and Belts, said: ‘Rollin Press Plast 4 contains a new polyurethane covering specifically designed for marrying rolls in the process of tissue converting. This incorporates several features that enable higher levels of productivity. For example, antistatic properties prevent the deposit of residues on the roller and allow for an easier cleaning operation.’
Other features include an extended mechanical stress resistance and longer lifetime, plus excellent bonding of materials during production. Rollin Pless Plast 4 offers a high abrasion resistance, good dimensional stability and low surface roughness.
A wide range of features has been built into this latest roller covering and these are designed to improve quality and productivity – antistatic properties, abrasion resistance, dimensional stability, low surface roughness, extended mechanical stress resistance, ability to match different nip footprints, plus increased specific pressure which allows a narrow nip footprint.
‘Press Plast 4D withstands load changes while maintaining an even nip footprint and is therefore suitable for the most versatile production situations,’ added Guillaume. ‘The ability to clean the roller easily and quickly reduces downtime, while the outstanding rebound of the compound allows perfect assembly of the plies, preserving production thickness, with an even bulk along the entire log.’
