Envelope inserting apparatus
First Claim
1. An inserter comprising:
- an insertion station;
means for feeding a succession of envelopes, one at a time, to the insertion station with the bottom edge of the envelope leading and the envelope flap in an open position and trailing;
envelope opening means at the insertion station;
a sensor arranged to detect the leading edge of the envelope as it is fed to the insertion station and, in response thereto, to cause the envelope opening means to open the envelope after its arrival at the insertion station; and
means for feeding a respective document into each open envelope at the insertion station wherein the sensor being also arranged to detect whether the flap of the envelope, when at the insertion station, is not in its open position and, when this is the case, to stop operation of the envelope feeding means and document feeding means for the next envelope and document, respectively.

Abstract
An inserter is disclosed having an insertion station and a feeding mechanism for feeding an envelope to the insertion station with the bottom edge of the envelope leading and the envelope flap in an open position and trailing, envelope opening mechanism at the insertion station and sheet feeding mechanism. A sensor detects the leading edge of the envelope as it is fed to the insertion station and, in response, causes the envelope opening mechanism to open the envelope after its arrival at the insertion station. The sensor also detects whether the envelope flap, when the envelope is waiting at the insertion station, is not in its open position and, when this is the case, it terminates operation of the envelope feeding mechanism and sheet feeding mechanism for the next envelope and sheet.
