Metso Paper has been selected to convert Otsego Paper Inc's PM 1 corrugating medium machine to gypsum linerboard production. The value of the order is not disclosed.

Metso's delivery will include a new three-ply forming section with a ValFormer unit, modifications of the drying section and a modernization of the reel. Metso Automation will supply consistency analyzers for the machine's wet end.

The delivery features the second ValFormer forming section for boardmaking applications. ValFormer is Metso Paper's new state-of-the-art hybrid forming technology, which utilizes vacuum shoe technology.

The 4.5-m-wide (179 in.) PM 1 board line will produce high-quality gypsum linerboard in a basis weight range of 160-205 g/m² (33-42 lb/1,000 ft²).
