Abstract
An apparatus and method for removing contents from an envelope are disclosed. In the apparatus a front envelope wall is severed from a rear envelope wall along three of the folding edges, the envelope is separated from its contents and finally the separated envelope is removed along an exit track. The exit track passes along the outer side of the apparatus and is at least in part externally visible. The envelope is transferred to said exit track in an unfolded condition and transported along the exit track with its former inner surfaces of the envelope walls turned away from the apparatus. The invention provides a possibility to check visually in a simple and efficient manner whether the contents of an envelope have been removed completely.
