Helsinki -- Metso has launched CoteCondor, a new polyurethane roll cover for blade-coater backing rolls. The Finnish roll coater said CoteCondor can be used for all blade coaters, but is especially designed for those using hard-coated coater blades.
The company claims to be the first supplier to make polyurethane covers for this use, and says "the CoteCondor cover is our solution to roll-cover edge-wear problems."
It uses a PU material with extremely good wear and marking resistance, the company added.
Metso says hard-coated coater blades are widely used in blade coaters, with benefits of better runnability, improved paper profiles, and longer coater-blade lifetimes. Despite these benefits they have a disadvantage - wear of the backing roll cover, particularly in the edge area where the roll cover and blade are in contact with each other.
A new hard-wearing polyurethane compound means the CoteCondor cover's wear and marking resistance is significantly better than that of conventional roll covers, giving much longer cover running periods on the machine.
Also, Metso notes, with the CoteCondor cover, the amount of material removed in cover regrinding is significantly reduced, which in turn leads to a longer total lifetime.
The CoteCondor cover material significantly reduces regrinding and roll-change costs, according to Metso.
Metso is a technology supplier to the paper industry, where its pulp, paper, and power experts specialise in processes, machinery, equipment, services, paper machine clothing, and filter fabrics.
