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.

OptiSizer Pond sizing

Pond size application technology is primarily designed for specialty paper grades, heavy printing papers, and for board when through-sizing is needed.

Sizer roll covers

The film sizing and film coating process have a direct impact on paper and board quality, both on paper strength as well as on paper appearance. Moreover, as on-line processes they are critical for the paper machine line efficiency. This puts high demands on the sizer roll covers.

Doctoring products

Doctoring affects machine runnability, paper and board quality, production costs, and production efficiency. Runnability can be improved by optimizing doctoring parameters and blade materials. Cleaner rolls result in better end-product quality. The blades can be selected to meet customers shutdown schedule which will lead to fewer blade changes resulting in lower blade costs. The reduction of unplanned shutdowns and costly downtime periods can be avoided by reliable and trouble-free doctoring.

Sizer consumables

Sizer consumables play an important role in film sizing and coating. When you choose products that are optimized for your machine and process, you chieve outstanding paper quality, maximized production capacity and a stable process. Our consumables have excellent wear resistance – meaning less downtime and fewer consumables used, and, thus more production and lower costs. 

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.
