Envelope filling machine

Image Number 6 for United States Patent #7475522.

An envelope filling machine for introducing sheets into envelopes includes a sliding surface, for transferring the sheets to an envelope filling station by means of pushing lugs, operated along the sliding surface. An envelope supplying conveyor supplies individual envelopes to the station placing them between vertical shafts of a pair of screws. The turns of the screws hold the sides of the envelopes and move each envelope downwards keeping the envelope separated from a subsequent envelope. When the envelope has come to rest on a conveyor belt placed between and under the screws, the lugs push the sheets into the envelope kept steady by movable stop strips yieldingly maintained by elastic means. When the sheets are fully inserted, the lugs push the envelope and force the movable strips to swing and let the filled envelope leave the envelope filling station.
