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.
A method for removing contents from an envelope having a first and a second panel at least partially severed along three folding edges and interconnected along a fourth folding edge, comprising the steps of:
An apparatus comprising a station for facilitating access to the contents of an envelope substantially severed along three of its folding edges, said station comprising a transport track, friction surfaces on opposite sides of the transport track and facing each other, of which friction surfaces at least one can be pressed towards the other friction surface and can be moved relatively to the other surface in at least one direction substantially parallel to the transport track, and a restraint spaced from the transport track and the friction surfaces, the friction surface on the same side of the transport track as the restraint being displaceable away from that restraint.
