High Resolution™ Forming System for Packaging Grades of Paper

For years, papermakers have looked for the best combination of drainage and formation in the early section of fourdrinier paper machines. The ability to maximize drainage without sealing the sheet and to control sheet activity over a wide range of basis weights have been challenges with increasing machine speeds and customer quality demands.

A Filtration System Design By and For Papermakers

Pressure filters are used extensively in the papermaking process and often go unnoticed as they effortlessly operate in stable mill water systems. They quietly perform as designed preventing shower nozzles from plugging and assuring that paper machine clothing remains clean. Pressure filters protect process equipment by removing contaminants such as sand and silt from mill water.

Paper Moisture Control to Reduce Curling

During the paper manufacturing process, many scientific processes are manipulated to control the physical properties of the paper such as weight, thickness, color, strength, and moisture. While most of these variables remain fixed after the paper is made, the moisture content begins to change almost immediately.

Nanotechnology Enhanced Doctor Blades Meet the Challenge

Nanotechnology, as it applies to doctor blades, is a microscopic filler material that is used to enhance the doctor blade performance. It’s added to resin to make the blade denser with higher peel strength and improved chip resistance. This stands out from a typical composite blade and allows for better wear resistance and roll cleaning.
