Description
The semi automatic sheet former offers increased productivity with reduced the operator fatigue. The machine consists of a strong and stainless steel table with a waterproof polypropylene working top, a built-in sheet-former, couch plate, pneumatic valves, control cabinet, control panel, etc. Pneumatic couching eliminates the handling of the 13 kg couch roll or weight.

Test description
By pressing the “Start” button the filling of the forming column commences. When it is about half full the prepared sample is added. When reaching the correct level the water supply stops and compressed air is injected for agitating the slurry. Then 5 sec are allowed for the turbulence to cease (10 sec according to ISO). After automatic de-watering the sheet is finished and the former can be opened. Two dry blotters and a couch disc are placed on top and the pneumatic couch plate lowered and locked. After the automatic couching cycle the sheet can be taken out and is ready for further pressing and drying.

• Mixing by compressed air ring of jets inside the sheetformer
• Pneumatic couching
• Sheet forming cycle fully automatic, but may be controlled by a 6-position switch (in manual mode)
