ABSTRACT:
The apparatus includes a removal arm which is provided at its front with two cooperating rollers to grip a printed product and with a movable flap in front of the rollers. A cylinder-piston unit can move the two cooperating rollers in the same plane and linearly to the first conveyor path. The cylinder-piston unit is controlled in such a manner that at least the extraction speed of the two cooperating rollers is proportional to the transporting speed of the first conveyor path. The apparatus is provided to serve as a turnout switch or to separate an overlapping stream of laterally offset, folded together printed products.
