An apparatus for separating stacked printed products includes suction heads anchored on a rotor by a respective swivel arm. The swivel arms are driven with regard to their swivel position by a swiveling drive superposed on the rotary drive of the rotor such that they enter the takeover point in pushing operation and leave the latter in pulling operation. At the deflecting point, the suction heads have time to suck against the edge of the respectively outermost product; by their tilting movement at the deflecting point, the seized product edge is separated definitely and reliably from the neighboring product. In connection with a transporting-away device with grippers circulating successively one after the other, the edge of the products is placed into the grippers by the suction heads swiveled during the circulation.

An apparatus for individually separating stacked printed products, the apparatus comprising: a rotor including a rotary drive for driving the rotor; a plurality of controllable suction heads which circulate in a plane perpendicular to the stack, the suction heads being mounted in the rotor and individually moveable; a drive superposed on the rotary drive for individually moving suction heads; a takeover region having a takeover point wherein the suction heads suck against the outer-most product and separate it from the stack to transfer it to a transporting-away device at a transporting-away point; a swivel arm, for each one of the suction heads, which anchors the suction head to the rotor, the swivel arm being substantially rigidly connected at one end on the suction head and having another end; the drive comprising a follow-up control which guides the other end of the swivel arm, the follow-up control having a follow-up roller engaging a control cam including a track which is stationary and closed in itself; and the control cam configured such that the swivel arm runs into the takeover point in pushing operation and leaves the takeover point in pulling operation and such that starting from the takeover point, the swivel arm is driven in a swiveling manner forward in the direction of rotation and is held swiveled in pulling operation from the takeover point to the transporting-away point of the transporting-away device.
