Test Description:
The former column is half filled with water then the pulp suspension, which has been prepared in a disintegrator and equalizer, is added. Water is added to the column up to the fill mark on the column. The agitator is used to swirl the content of the former column. Once the settling phase has ended, the second hand-lever is shifted to open the drainage valve causing the former column to drain. The formed hand-sheet remains on the screen. The former column can then be opened, and two blotting sheets are placed on top of the wet hand-sheet. With the stainless-steel roller, the sheet is couched and then carefully be removed from the screen so it can be further processed with a sheet press, drying rings, or a speed dryer.
