Metso has launched polyurethane roll covers for tissue machine press and suction press rolls.
The new PressHusky and VacuHusky roll covers are designed especially for Yankee press applications widely used in dry crepe tissue production.
As an option, a Metso iRoll online nip profile measuring system can also be applied with these new roll covers.
The company said: “Some tissue grades are sensitive when it comes to bulkiness and thickness so lower nip pressures are preferred in pressing. “Traditionally, this has been a limitation in the use of polyurethane roll covers in Yankee press applications.
“However, the new polyurethane material of PressHusky and VacuHusky covers offers several hardness alternatives and more options for cover topography, which results in maximized dewatering and the desired tissue quality with high bulkiness and thickness.”
PressHusky and VacuHusky covers also provide lowered operating costs due to the reduced need for regrinding.
Their low rolling resistance creates energy savings thanks to reduced roll drive power.
In addition, solid press rolls with a PressHusky cover can be operated cost-efficiently without internal water cooling.
