ABSTRACT:
A vacuum release assist system for a document insertion station is described. The vacuum suction cup system is used for opening an envelope. The vacuum release assist system ensures that the suction cup is timely released during the removal of the envelope from the insertion station. In one configuration, a solenoid actuator is used to push away the envelope from the suction cup. In another configuration, a blow-off valve is used to introduce positive air pressure to timely release the suction cup.
