The warp resistant stainless steel frame is a robust base for the work table, in which two pumps, hot water baths, the control unit, a return water filter and the water container are installed. A former column, dryers, 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. Different programs can be stored in the program control system, and can be reloaded
at any time. Between the former column and dryers there is a spacious work space for removing the manufactured hand sheets and preparing them for drying.
From the equalizer (see page 34), suspension is taken. Water is introduced to the former column automatically when the start button is pressed. When it has been filled to the 4 litre mark, the suspension is added. When the 7 litre mark is reached the flow of water is stopped automatically. After the agitation is completed, the suspension comes to rest and is drained through a screen. The hand sheet is left on the screen frame. To provide it with the desired stability it is briefly treated with vacuum.
Then the former column is opened, the hand sheet covered with a carrier board and couched. After detaching it is given a cover sheet and put into the dryer. There the sheet is dried for the preset time (5 – 6 mins). After the drying is complete, carrier board and cover sheet are removed. The sample can then be made ready for further tests.
The water used in making the sheet is not drained away, instead it is collected in a separate acrylic glass tank. It can be operated at room temperature, or heated up to 65 °C. It can be removed for testing (e.g. chemical residue etc.) via the sample outlet on the side of the table.
