Abstract
In a mail-handling machine for processing mixed mail, a flap-stripper for opening the flap of an unsealed envelope is mounted for rotation to intercept and detect a mis-sealed envelope to avoid jamming the machine. A deflecting finger with a small idler roller pushes down on the envelope before it reaches the flap-stripper.
