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.

Apparatus for filling a valved sack, comprising:
- at least one filling pipe in fluid communication with a feed unit and having one end for receiving the valve of a valved sack, said filling pipe defining a filling axis and including at least one elongated slot-like recess extending in the axial direction defined by said filling axis over a defined area;
- and
- clamping means movably mounted relative to said filling pipe for engagement in said recess and application of a tension force onto the valve of the valved sack during a filling operation so as to tense and enable the valve to closely bear along its entire length against the outer surface of said filling pipe.
In a filling apparatus of the type having a filling pipe for receiving a valved sack, a clamping device for sealing engagement of the valve of the valved sack upon the outer surface of the filling pipe comprising:
- a clamping lever having one end engageable in an elongated recess extending in the axial direction defined by the filling axis of said filling pipe of the filling pipe after a valved sack is placed over an outlet port of the filling pipe;
- and
- a drive unit acting upon said one end of said clamping lever for applying a tension force in direction of the valved sack to push the valve into the recess and thereby allow the valve to closely bear over its entire length against the outer surface of the filling pipe.
