The present invention provides a transfer device for receiving a series of flexible products from a single path and delivering the flexible products to a plurality of paths where they can be separately stacked and packaged. The device includes a vacuum transfer drum and apparatus for rotating the drum. The transfer device also includes a rotating product drum for supplying flexible products such as plastic bags in a single row along a path to the drum. Further, the transfer device includes apparatus on the drum for securing the leading edges of the flexible products to the surface of the drum, for shifting selected flexible products transversely from the path as the drum rotates, and for securing the trailing edges of the selected flexible products during the shifting thereof. This transverse shifting of selected flexible products permits delivery by the transfer drum along a plurality of paths.
