The FA 40 processes pre-made block-bottom paper bags in fixed-cycle operation, but can also be adapted for other suitable bag types, e.g. side-gusseted bags without blockbottom, and different bag materials. The operating speed of the cam-controlled machine is continuously variable. Following product settlement, the bag is presented to the standard pre-folding facility which, depending on filling level and type of bag closure, ensures cam-controlled pre-folding above the filling level. Depending on the requirements, the machine can be equipped with additional features, such as intensified vib ration, additional check weigher system, high-efficiency dust evacuation connections and special features for quicker format change-over.
