ABSTRACT:
A method of opening an envelope along three edges, in which the envelope is moved to an opening or edge removing device along a supply path, one edge being guided along said device for cutting open or removing the edge. Next, the envelope is rotated through 90.degree. to be subsequently guided again along the opening or edge removing device for opening the second edge, which cycle is repeated for the third edge. An apparatus for performing this method includes a housing having an inlet path leading to the supply path along which the opening or edge removing device is arranged, a first set of members for moving and guiding the envelope co-extensively with the inlet path, and a second set of members for moving and guiding the envelope in a direction perpendicular to the inlet path along the opening or edge removing device, and a third set of members for guiding and moving the envelope along a quarter-circular path, which returns the envelope, turned 90 degrees, to the first set of members in the inlet path.
