Customer case:
Roll change interval increased from one to two years in Papierfabrik Adolf Jass
When recycled paper is used, more impurities are created compared with primary fibers. This may cause stronger seal wear. Papierfabrik Adolf Jass solved the problem with Valmet’s non-contacting suction roll axial seals.
We have hit our target for increasing the roll running time and the system operates satisfactory. We would go for it any time again.”
Summary
| Location | Papierfabrik Adolf Jass in Fulda mill, Germany |
| Customer challenge | Maintenance interval of the rolls equipped with axial seal strips was originally between 8 and 9 months at the mill. |
| Solution | Valmet has modernized the suction rolls of PM3 and PM4 with Valmet Lock Seal seals. Lock Seal operates mainly without contact or with a very light contact with the inner surface of the roll. Thanks to low friction, the lifetime of the roll is increased significantly. |
