Envelope flap opening device

摘要

This device reduces the size of the gap between the apex of the flap opener blade and the drive roller. The above increases the probability that the flap of the envelope would be opened. The foregoing was accomplished by removing segments of the apex of the flap opener blade to allow clearance for the envelope and/or drive roller. Thus, the nominal position of the apex of the flap opener blade was moved closer to the drive roller which reduced the gap between the apex of the flap opener blade and drive roller. Consequently, the chance that the envelope flap would be closed was reduced.
