Abstract

See full text

An envelope to be opened and emptied has a first and a second panel (12, 13) at least partially severed along three folding edges and interconnected along a fourth folding edge. A portion of the first panel is moved relatively to the second panel in the direction of the fourth folding edge and pivoted about the fourth folding edge. According to the invention a portion of the envelope adjoining the substantially severed folding edge opposite the fourth folding edge is curled and subsequently the edge of the second panel opposite the fourth folding edge is withheld by a retainer from following the movement of said portion of said first panel. Envelopes of which the front and the back panel are not completely severed along three folding edges can mechanically and reliably be opened and emptied.
