An envelope flap opening apparatus 11 includes a suction cup 21 mounted on a slidable rotatable shaft 23. The shaft 23 both rotates the suction cup 21 so as to partially open an envelope flap 17 engaged thereby and advances the suction cup 21 alongside the travelling envelope 15 until the partially opened flap 17 passes beneath a stationary blade member 91 which fully opens the envelope flap 17.
