OptiPress Center

Center roll based press section is a reliable, well-known concept combining close to 40 years of pressing technology experience with modern shoe press technology. A shoe press replaces a roll just before the first open draw. The resulting boost in dryness thus fully benefits web runnability in the open draw.

Leading technology for superior runnability and maximal web stability

Runnability systems stabilize the run of the web and secure tail threading in the dryer section. In practice, the equipment helps to hold the web in contact with the fabric by creating underpressure on the other side of the fabric. The underpressure is created by blowing, suction, or a combination of both. 

Impingement drying

Revolutionary drying technologies for effective air drying.

Capacity increase for rebuilds

OptiDry Vertical is an impingement dryer, which increases drying capacity without adding machine length. It is installed under the existing dryer section. OptiDry Vertical suits all paper and board grades and can be use with any dryer section layout.

OptiAir Hood

OptiAir Hood combines systems for ventilation, runnability and heat recovery, thus providing excellent tools for controlling drying performance and maintaining energy efficiency.

Sizing

Valmet’s sizer product family offers all application methods and all paper machine sizes available - spray, film and pond application and a new type of a sizer with hard nip rolls and curtain sizing. All sizers have a robust and modular construction combined with high functionality and quality with a low total cost of ownership. In surface sizing or size application, starch, or other types of size or pigmented size, is applied to the paper web surface to improve its strength, surface properties or water resistance. Sizing is often used to modify surface properties before coating.

OptiSizer Curtain sizing

The new surface sizing method applies the starch as a curtain of size. When combined with hard-covered rolls the results with coated cartonboards are significant: stiffness, quality and production increased, and energy and raw material consumption reduced.
