Abstract
An envelope feeder using a combination of frictional force differentiation and three discrimination edges, two of which are provided by flexible materials spaced apart from and on either side of a metal envelope separating plate to prevent multiple envelope feeds into printers. The flexible plate on the media side of the metal envelope separating plate is at a more acute angle to the vertical than the metal envelope separating plate, and the metal envelope separating plate of the invention is at a more acute angle than the angles used by metal envelope separating plates in the prior art. A third discrimination edge is provided by a flexible plate which is behind the metal envelope separating plate and which has an angled portion which is longer than the angled portion of the metal envelope separating plate so as to extend past the end of the angled portion of the metal envelope separating plate by about 0.15 inches.
