Oscillating lane guide segments define a diverging laterally shifting path for the articles tending to break up the nested articles and to facilitate feeding the articles in orderly rows more suitable for a conventional case packer. Left and right primary lane guide elements are pivotably mounted to the downstream ends of left and right stationary intake lane guides. Left and right secondary lane guide elements are pivotably mounted in turn to downstream ends of the primary lane guide segments. An actuator is provided for oscillating the left and right primary lane guide segments.
