ABSTRACT:
The opening apparatus has an opening element with a resting surface and a stabbing member, the pointed stabbing end of which is offset by a predetermined distance with respect to the resting surface. The printing product to be opened is held together between the resting surface and the counter-element. Upon pivoting of the opening element in stabbing direction, the stabbing member stabs in between sheets of the printing products, which are lifted off one another upon further pivoting of the opening element.
