Abstract: A rack packer for loading containers onto a rack comprises a loading station, a transfer station, an elevator, and a rack positioning means. The loading station receives and supports successive incoming rows of vertically oriented identical containers. The transfer station is positioned adjacent to the loading station. A starwheel at the transfer station is rotatably mounted about a transfer axis parallel to the successive rows of containers at the loading station. The starwheel has multiple sets of radial arms extending from the transfer axis to support individual containers of each row. The starwheel moves successive rows of containers from their vertical positions at the loading station upwardly to horizontal positions above the loading station. The elevator is located adjacent to the starwheel to receive multiple rows of horizontally oriented containers from the starwheel.
