Description

The shower is mounted on the paper machine frame for cleaning the roller surface, and the inner part of the roll is separated from the paper side with a jet tube to prevent the pulp from being thrown or stained. When the roller surface works normally, the copper net is pressed down 2-3 centimeters, so the wet paper radiation is pressed, the density is increased, the surface is pressed by the bar, and the proper net mark is left on the paper surface. With the decrease of pressure in the compression zone, there is a certain negative pressure in the wedge region at the exit of the compression zone.
