swing between production of plain and textured tissue with low energy and fibre consumption. It has a design speed of 2,000 metres per minute in plain mode and 1,800 metres per minute in textured mode, offering capacity of 70,000 tonnes per year of bath, towel and napkin tissue grades. “Our strategy is to provide something different to the market. To succeed, we had to look for a new and innovative technology, so the choice fell
on the Valmet Advantage NTT concept. We are also using 100 per cent virgin pulp, and all in all, it has paid off. Today, we are producing great tissue products with very high bulk and softness,” says Marco Monsalve, operations manager at FPC. Gunnar Söderqvist, project manager of Valmet’s tissue mills business unit, added: “The cooperation between Valmet and the mill team has been great, and we enjoyed working with the
people in FPC.”
The machine is equipped with an OptiFlo II TIS headbox and a cast iron Yankee cylinder. It also features the well-proven Advantage tissue technology, including the AirCap Yankee hood, a SoftReel reel and the WetDust dust management system. The delivery features a Valmet Focus Rewinder and an extensive automation package including Valmet DNA, dilution control, and quality control systems.
