Abstract
Apparatus for filling valve sacks includes at least one filling pipe in fluid communication with a feed unit and receiving a valved sack. The filling pipe is provided with least one axial slot-like recess which is engageable by a clamping lever after a valve sack is placed over the outlet port of the filling pipe so as to apply a tension force onto the valve of the sack. In this manner, the valve of the sack is pushed into the recess and drawn against the outer surface of the filling pipe to attain a sealing action which is maintained even when pressure causes a widening of the valve because the clamping lever is then further lowered.
