Abstract

The machine has a set of wheels and a set of backing wheels for bringing envelopes into a filling position where they face a mail path, and holding them therein, the mail path having mail advance means and envelope body opening fingers. The set of backing wheels (4) is coupled via a free wheel mechanism (26) to the mail advance means (8) and is controlled to leave a retracted position once an envelope is in a filling position to return to a position where it presses against the set of wheels (3) by means (17, 35-36) for detecting that an item of mail has been partially inserted into the envelope, and is stopped together with the mail advance means by means for detecting that the item of mail has been fully inserted into the envelope. The invention is applicable to processing mail.
