The Bosch Form Fill and Seal machine works intermittently. The thermofoil will be subtracted from the storage roll, locking through a H2O2 bath and afterwards dried in the sterile-area of the machine. After passing the pre-upwinding, the sterilized thermofoil will be heated and formed by sterile air pressure. After that, the formed cups will be transported intermittent to the filling area of the TFA 241, where the cups will be filled with coffee cream for example. The sterilized cover film will supplied to the formed and filled cups under sterile conditions.
Inside the sterile area, the cups will be pre-sealed by a sealing station. Shortly after the cups have leaved this area, the closing will be effected by a main sealing station.
In a cooling station, the cups and also the therforming- and sealingtools will be cooled down through circulating water. In the next machine station, the bundles will be blanked to single cups. A blanking tool for e.g. 5 items bundles are also possible again a little charge.
The blanked cups will be transported out of the machine through a discharge conveyor belt or a chute. The lead frames will be rolled on a further roll.
