Rebuilds and improvements

Paper machine rebuilds offer ways to remove production bottlenecks, reduce production costs, improve operating safety, save energy or add new grades with paper machine conversion.

OptiFlo headbox for low speeds

The redesigned OptiFlo headbox's turbulence generator provides top-notch quality for specialty paper grades, even when the paper machine is running at speeds as low as 120 m/min.

Cost effective dilution control upgrade for hydraulic headboxes

Valmet's dilution control up grade, Valmet Dilution Retrofit*, is designed for hydraulic headboxes. It provides a cost-effective way to upgrade an existing slice lip-controlled headbox to a dilution-controlled one during an extremely short shutdown.

Hybrid with shoe blade

A proven solution for hybrid forming is OptiFormer Hybrid, a former equipped with a top forming unit that uses shoe and blade technology. OptiFormer Hybrid utilizes unique VacuShoe technology to boost the output quality and capacity.

Press section

The trend towards lower basis weights, higher speeds, lower-grade raw material, closed production cycles and demands for further improvements in printability place special demands on press section configurations. Valmet’s press section solutions are designed to ensure the consistent levels of efficiency required for high quality and runnability.

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.
