ABSTRACT:
Apparatus for stripping a single envelope from a stack of envelopes without misfeeding or double feeding is provided. The apparatus includes a picker blade which is articulated by a drive to impart of plurality of motions to the leading edge of an envelope after the picker blade has been engaged under the flap of an envelope to be separated from a stack of envelopes in a magazine. The novel stripping action of the picker blade ensures that the leading edge only of the envelope to be fed from the magazine is first stripped and separated from the stack of envelopes and directed past a restrainer which prevents the stack of envelopes adjacent the envelope to be fed from being moved in a feed direction.
