A gripper for conveying printed products is disclosed. The gripper has two gripper parts mounted so as to be pivotable on a shaft which, in turn, is mounted rotatably in a holder. Connected to this shaft so as to be fixed against rotation is closing lever which bears at its end a follower roller which interacts with fixed closing links or cams. Furthermore, a resting part for a compression spring is connected to the shaft via a spreader ring so as to be fixed against rotation. This compression spring is supported at its other end on a bearing part which is integral with the one gripper part. A pivot movement of the closing lever results in a corresponding clockwise pivoting of the resting part. As a result, pivoting of the one gripper part into the clamping position is brought about via the compression spring. This one gripper part is blocked in its clamping position in which the compression spring is compressed and exerts a corresponding clamping force.

A gripper for a conveying device for conveying single-sheet or multiple-sheet printed products, such as newspapers, magazines and parts thereof, comprising: a) a first gripper part and a second gripper part which can be moved relative to one another, the first gripper part being mounted to pivot about a pivot axis such that it can be pivoted from an open position to a clamping position in which it interacts with the second gripper part to clamp a printed product under a spring force; b) a pivotably mounted closing lever which interacts with a fixed closing cam arranged along the path of travel of the gripper to pivot the first gripper part into the clamping position; c) a locking device for blocking the first gripper part in its clamping position, the locking device being releasable by a stationary opening arrangement along the path of travel of the gripper; d) a further gripper part which is coupled to the closing lever for common pivotal movement with the closing lever; and e) a spring element which is arranged between the first gripper part and the further gripper part which is coupled with the closing lever for common pivotal movement, the spring element being tensioned during the closing movement of the gripper, the spring element transmitting the pivot movement of the closing lever to the first gripper part, and the spring element generating the closing force when the first gripper part is blocked in its clamping positions.
