Modern paper machines have reached their practical maximum width, because raising the width would require significant investments to eliminate vibrations of the cylinders at high speeds. To increase the amount of produced paper on a paper machine, web breaks, broke and downtime in general should be minimized and the production speed maximized. In many cases, the increase in paper machine production speed is limited by the mechanical properties of wet web and paper machines are thus forced to run below their design speed. Therefore obtaining knowledge about what kind of chemicals could be used to improve wet web mechanical properties would be valuable.
