ABSTRACT:
The present invention provides an improvement in a stacking device having an urge roller, an input guide, a spring loaded backup paddle and a registration wall. The improvement comprises a series of ramp-shaped fingers located between the urge roller and the registration wall. The ramp fingers guide the lead edge of an envelope in such a manner as to create a pocket between the surface of the envelope and the ramp fingers. The lead edge of the next envelope follows the ramp fingers and thus is not forced against the surface of the previous envelope. As a result the lead edge of the second envelope will not catch on the external side seam of the first envelope.
