Apparatus for opening envelopes, characterized essentially by being constituted by an elongated base base and weight sufficient to be seated statically on a smooth surface and provided with a longitudinal grooved upper guide for the sliding of the envelopes disposed on edge, being mounted on the inside a housing provided on the stand, a support carrier with two vertical axes provided with respective rollers, in the same plane, under an opening of said guide, one of said rollers having a circular blade and a protrusion annular drive projecting through a lateral opening of the stand, the rollers being conveniently separated from each other to allow passage of the envelope, so that one of the two sheets of the envelope rests against the edge of the knifeless roller, and the blade acts against the other blade of the envelope, cutting it and thus determining the opening of the envelope.
