Wepa Lucca, Italy, this week reported that it has completed and started up a major rebuild of the wet end section of its No.1 Tissue Machine (TM 1) in Cassino, Italy. The rebuild, done by Toscotec, was conducted in a compacted time frame, from Christmas to New Year's Eve of last year.
The original TM 1 configuration in Cassino was a Tisco Former from Esher Wyss, dated 1987, with a grooved 18 ft dia. yankee dryer. The machine has a paper trim at the reel of 5,300 mm with a maximum running speed before the rebuild of 1,700 m/min with a limitation on production of low basis weights. The project goal was to rebuild the machine into a crescent former configuration to improve speed and paper quality as well as runnability and maintenance.
A few days after startup, a sustained operating speed of 1,800 m/min was reached on low basis weight with improved paper quality. With this machine upgrading, the Cassino Mill says it can now optimize the production cycle both in terms of maintenance and flexibility.
