ABSTRACT:
An envelope stacking machine has a conveyor for feeding envelopes in a substantially vertical orientation along a predetermined path of travel. There is an elongate envelope stacking support for receiving envelopes directed to the support from a transfer device which pushes the envelopes against an envelope abutment member having a force converting apparatus attached thereto for maintaining a substantially uniform resisting force against the incoming stream of envelopes. The force converting apparatus contains resilient and flexible devices which operate in conjunction with a rotary displacement device to achieve the substantially uniform resisting force.
