Introduction
Hans W Maurer is a notable inventor based in Highland, MD (US). He has made significant contributions to the field of paper manufacturing, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is a method for providing irreversible smoothness in a paper rawstock. This method involves applying a liquid film to a paper or paperboard rawstock web in a controlled and uniform manner. The goal is to achieve a moisture gradient in the Z-direction thickness of the web to a depth of less than about one-half of the web thickness. After this application, the treated web is pressed in at least one nip of a calender device before drying. The liquid application plasticizes only the surface fibers, allowing the paper fibers at or near the surface to become deformed and bonded under pressure. This results in a substantially irreversible smoothness when the paper is rewetted in a coating application or similar process.
Another significant patent is for a tandem calender, which is designed for the output end of a paper machine. This calender includes two single stack nips in-line. The first nip is formed by a pair of lightly loaded steel rolls, while the second nip consists of a steel roll and a plastic-covered roll that is loaded 2-10 times greater than the first nip. This innovative design enhances the efficiency and quality of the paper production process.
