A device for turning an editorial product on a packaging line includes a pusher conveyor, a feeder for products to be packaged, and a plurality of feeders for sheet inserts for the products, arranged side by side one after another along a direction essentially perpendicular to the pusher conveyor. The device has a base on which there is mounted a unit for gripping, rotating, overturning through 180° and guiding the products caused to advance by the pusher conveyor. The base has an overall size identical to that of one of the insert feeders so as to be able to assist in its position within the line. A drive is also provided for the unit
