Sheet former Rapid-Köthen Manual
For the production of standardised hand sheets with a diameter of 200 mm.
The warp resistant stainless steel frame is a robust base for the work table, in which a pump, hot water bath, the control unit, a return water filter and the water container are installed. A forming column, dryer, the water circulation system, and the controls are mounted in the waterproof table surface. The control panel contains easy to read instruments and a timer for each dryer as well as a vacuum display. Between the forming column and dryers there is a spacious work space for removing the manufactured hand sheets and preparing them for drying.
Suspension is taken from the equalizer (see page catalogue). The individual steps are carried out manually via the selector switch. At first water is introduced into the forming column. When it has been filled to the 4 liter mark, the suspension is added. When the 7 liter mark is reached, the flow of water is stopped manually and agitation begins. After the agitation is completed, the suspension comes to rest and the draining process starts. The hand sheet is formed on the screen frame. To provide necessary stability it is briefly treated with vacuum. Then the forming column is opened, the hand sheet is covered with a carrier board and couched. After removal it is covered by a cover sheet and put into the dryer. There the sheet is dried for the preset time (5 – 6 min). When the drying is complete, carrier board and cover sheet are removed. The sample then can be prepared for further tests.
