ABSTRACT:
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.
