Keeping the press rolling

The PM7 is one of the world’s most modern machines for the production of newsprint. It is rated to convert recycled paper and primary fibres into 360,000t/yr of newsprint at an outstanding speed of 1900 m/min. It is a giant of a machine that operates at the Swiss firm Perlen Papier AG, around the clock, 365 days/yr and a range of Loctite products are playing their part in ensuring its reliable service.

A short window of time, just a few hours, is allocated each month for maintenance. The inner workings of the PM7 comprise many hundreds of rollers, cylinders, pumps, drives, pipes and valves and Henkel Loctite is used for cleaning, bonding, sealing and lubricating these vital components. Moist cellulose is sprayed onto rollers of the PM7 as part of the paper production process and it is essential that this, as well as surplus hydraulic oil, is effectively removed so the Loctite anaerobic adhesives can achieve the best possible bond and seal. For this purpose the maintenance team uses Loctite SF 7063 to ensure there are no contaminants to impede the efficiency of the processes.
