The transfer device is a circular conveyor having a plurality of radially moveable grippers. The grippers receive a non-self-supporting package, such as a newspaper jacket, on its bottom edge from an overhead line conveyor and rotate the newspaper down onto a receiving device such as a bundler at the bottom of the drum's rotation. The transfer device controls the gripping of the newspaper from the line conveyor with an inhibitor cam to provide a controlled bypass mechanism. The radial moveable grippers allow for smoother transistion and decrease space needs.
