    Description

    The semi automatic sheet former offers increased productivity with reduced operator fatigue. The machine consists of a strong sturdy stainless steel table with a waterproof polypropylene working top, a built-in sheet-former, pneumatic 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 starts. 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 dewatering the sheet is ready, 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.
