ABSTRACT:
A backstop member for use in an insertion station operative to insert an enclosure collation into an open end of an envelope. The insertion station having a deck with a transport mechanism for conveying an envelope, an opening mechanism for opening an envelope and a backstop member mounted below the deck for stopping the envelope in the insertion station preparatory to insertion of the enclosure collation. The backstop member includes an elongate stopping portion having a substantially planar surface configured to abut against and prevent travel of an envelope in the insertion station being driven by the transport mechanism when the elongate stopping portion is caused to extend above the deck. The backstop member also provides a cam portion having an ellipsoid configuration dimensioned to cause a portion of the envelope being driven by the deck transport mechanism to travel over the ellipsoid configuration and away from the deck in the insertion station when the cam portion is caused to extend above the deck.
