Printed products are transported in the direction of conveyance suspended, held by their fold, from transporting clamps of a conveying device. The end area of the printed products rests on a supporting mechanism and the uppermost product part protrudes with its marginal section over the bottommost product part. To the two product parts there is in each case assigned a gripper of the opening device. The grippers are disposed on a revolutionally driven drawing member. The clamping tongue of the first gripper grips underneath the marginal section and, upon running up against an opening crank, lifts the product part from the bottommost product part. The second gripper grasps the lifted-off product part in the marginal section and, when the clamping tongue is lowered into the closed position, the latter clamps the product part between itself and the clamping jaw of the first gripper, by the end edge. The first gripper revolves at a greater velocity than the second gripper. Thus, the two product parts are lifted apart in the direction of conveyance.
A device for opening folded, printed products such as newspapers and magazines and portions thereof, wherein each product is folded so as to have a fold between one product part and another product part, each of said product parts having an end edge opposite the fold and the end edges of both of those product parts forming an end area of the product facing away from the old, the device comprising:
