Patent ID: 8720494

Claim:
A method for filling valved bags ( 4 ) with loose materials ( 18 ), wherein by means of a filling element ( 3 ) a valved bag ( 4 ) to be filled is filled by means of a filling process, which filling process comprises at least a filling stage ( 40 ), a settling stage ( 41 ) and a discharge stage ( 42 ), wherein during the filling stage ( 40 ) at least one loose material ( 18 ) is filled into the valved bag ( 4 ) and during the settling stage ( 41 ) at least one settling phase ( 37 ) for venting is provided, and wherein during the discharge stage ( 42 ) the valved bag ( 4 ) is discharged from the filling element ( 3 ), wherein during the filling stage the material is filled by way of a coarse filling stream followed by way of a fine filling stream and wherein the filling by way of coarse filling stream occurs until a predetermined weight is reached and the filling by way of fine filling stream occurs until a target weight is reached and the feeding of material is terminated, characterized in that during the filling by way of fine filling stream and at least during a majority of time during the filling by way of coarse filling stream at least one squeezing device ( 5 ) externally applies a venting pressure ( 32 ) to the valved bag ( 4 ) so as to reduce the volume ( 60 ) available to the valved bag ( 4 ) and at least in the settling phase ( 37 ) the at least one squeezing device ( 5 ) applies a squeezing pressure to the valved bag ( 4 ) for venting the valved bag ( 4 ) and reducing the volume ( 60 ) available to the valved bag ( 4 ), until a predetermined reduction of the volume available to the valved bag ( 4 ) is achieved, whereupon the squeezing pressure ( 34 ) of the squeezing device ( 5 ) on the valved bag ( 4 ) is reduced and the valved bag ( 4 ) is discharged from the filling element ( 3 ) and wherein a parameter for the weight of the valved bag ( 4 ) is captured during the filling stage ( 40 ) and as the target weight ( 30 a ) of the valved bag ( 4 ) is reached, feeding of the material is cut off.
