A device for attaching a supplement to an exposed surface of signatures transported one after another in a transporting direction along a guide arrangement includes a rotating gripping roller for picking up the supplements at the circumference of the rotating gripping roller with a controlled gripping tool. The rotating gripping roller has a rotational axis arranged approximately at a right angle to the transporting direction and at least approximately parallel to the exposed surface of the transported signatures. An adhesive feeder is provided along a transporting path for supplements. A forward feed is operatively arranged with the rotating gripping roller to operate in cycle with the rotating gripping roller for placing the supplements approximately tangentially with respect to the rotating gripping roller so that the supplements are on the circulation path for the controlled gripping tool.
