An arrangement for producing stack bundles from signatures includes a horizontal stack deposit support, a conveyor to supply a flow of signatures to the stack deposit support for formation of a signature stack having a front end and a back end, and a supporting device adapted to form a stack bundle having a front end and a back end. The supporting device comprises a first support element adapted to rise from below the stack deposit support and act on the front end of the stack, a second support element adapted to rise from below the stack deposit support and act on the back end of the stack bundle, and a third support element arranged to rise from below the stack deposit support in a first location to act on the front end of the stack and in a second location to act on the front end of the stack bundle.
