Metso’s StreamLine Pro at NSI Skogn sets new capacity record in roll wrapping

The Metso Paper delivered StreamLine Pro wrapping machine at Norske Skog's Skogn mill is the highest capacity wrapping machine in the world. In October the StreamLine Pro wrapping machine provided newsprint rolls with kraft wrapper at a capacity of 190 rolls per hour, which is more than any other wrapping machine ever.

"The new wrapping line meets our expectations and we are pleased with the performance. It gives Norske Skog Skogn the best possible wrapping efficiency in terms of both costs and quality. This secures our leading position as a large-volume/ low-cost producer of high-quality newsprint," states Johan Kristian Oxaal, Project Leader at Norske Skog Skogn.

The StreamLine Pro wrapping machine represents the highest wrapping performance available and provides an excellent solution for centralized wrapping. At the Skogn mill the StreamLine Pro wrapping machine wraps all rolls from the mill's three paper machines, which produce a total of 600,000 tonnes of newsprint per year.

The record-holding wrapping machine is fully automated and features Metso Paper's latest Onesider technology. The unique Onesider solution actually divides the wrapping process into two sides – the operational side, which is open for visual roll flow control, and the material side, which offers optimized wrapping material infeed and replenishment to the wrapping process. A compact, one-sided machine needs considerably less floor space than a conventional multi-station wrapping machine.

Further, the StreamLine Pro wrapping machine is realized with Metso Paper's non-hydraulic principle, which means that all functions that have traditionally been done with hydraulic cylinders are now performed with electric gear motors. An all-electric system means no hydraulic oil leaks, no hydraulic power units and maintenance, and the elimination of environmental issues typically associated with hydraulics. Control of critical system functions is significantly improved with electric drives, and electric drives also deliver energy savings when compared to hydraulic systems.

According to Oxaal, a TCO (Total Cost of Ownership) evaluation, including elements like design, layout, logistics, ease of operating, energy consumption and investments, were the reason for Norske Skog Skogn’s decision to buy a Stream Line Pro wrapping machine.

Norske Skog Skogn, located close to Trondheim, is the largest producer of newsprint in Norway and one of the largest newsprint mills in Europe. The mill was founded in 1962 and the first newsprint machine started production in 1966. The mill operates three paper machines, which produce newsprint grades made from virgin fiber and de-inked pulp.

Metso is a global engineering and technology corporation with 2006 net sales of approximately EUR 5 billion. Its more than 26,000 employees in more than 50 countries serve customers in the pulp and paper industry, rock and minerals processing, the energy industry and selected other industries. www.metso.com
