Vacuum deck stopping mechanism
First Claim
1. 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 comprising:
- 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 of the deck when the elongate stopping portion is caused to extend above the deck; and
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.

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.

5. A system for transporting, deskewing and stopping an envelope in an envelope insertion station, comprising:
-
a plurality of laterally spaced, continuously moving, endless transport belts; a stationary vacuum deck having longitudinal grooves, each of the grooves accommodating an upper reach of a corresponding one of the continues moving transport belts, the vacuum deck including a plurality of vacuum ports arranged in longitudinal rows, each of the rows being adjacent at least one of the transport belts wherein vacuum is continuously present at each vacuum port; and a plurality of stop members located at the downstream end of the vacuum deck wherein vacuum at the vacuum ports urge an envelope against the continuously moving transport belts which transport the envelopes to the stop members, each stop member including; 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 belts when the elongate stopping portion is caused to extend above the vacuum deck; and a cam portion having an ellipsoid configuration dimensioned to cause a portion of the envelope being driven by the transport belts to travel over the ellipsoid configuration and away from the vacuum deck in the insertion station when the cam portion is caused to extend above the vacuum deck. - View Dependent Claims (6, 7, 8)

9. A method of handling an envelope at an insertion station, comprising the steps of:
-
providing a stationary vacuum deck having a plurality of longitudinal grooves and a plurality of longitudinal rows of vacuum ports; providing a vacuum source coupled to each of the vacuum ports; continuously moving endless transport belts through the longitudinal grooves; feeding an envelope to the upstream end of the vacuum deck; continuously urging the envelope against the continuously moving transport belts; pivoting stop members into a stop position to stop the envelope; and pivoting the stop members into a lift position so as to lift at least a portion of the envelope away from the vacuum deck.
