A process is described in which an oscillating gripper unit is utilized, having a gripper foot for the oscillating gripper member carried angularly fixed by the respective control shaft; during the return stroke of the gripper unit from the rotating cylinder of the printing machine towards the table carrying the sheets, the gripper foot is turned eccentrically with respect to the axis of its control shaft making this latter turn with appropriate means in a directional sense in concordance with that of the rotation of the whole unit in such a way as to produce a raising of it with respect to the gripper member such as to carry it out of the path of this latter while the axis of oscillation of the unit is maintained stationery with respect to that of the cylinder.
