Abstract

A mail handling machine includes a mechanism for serially transporting along a main path sealed and unsealed close-flapped envelopes, some of which may be mis-sealed. The machine also inlcudes a mechanism for opening the flaps of the unsealed close-flapped envelopes. The flap opening mechanism includes a shaped blade pivotally mounted on the machine and located along the main path. There is also a shaped portion of a deck that includes a fixed guide edge located along the path and downstream of the blade. The blade strips open the flaps of the unsealed envelopes. A member is hingedly mounted to the trailing edge of the blade. The member is biased so as to obstruct the gap between the blade and the guide edge to prevent opened flaps from entering the gap. When a mis-sealed envelope engages the blade, causing the blade to move pivotally, the shaped portion cams up the member, which contacts the mis-sealed envelope and urges it out of engagement with the blade.
