Abstract: Apparatus is provided for packing articles, for example apples and other readily damaged fruits, in a close-packed array. A first feeder operates to pack a first supply of the articles in spaced-apart groups and a second feeder operates to fill the spaces between these groups. The feeders are preferably rotary members rotating in a vertical plane and having circumferential depressions. These depressions cooperate with peripheral confining barriers, eg. belts, to carry the articles downwardly and release them as required. The packages for receiving the articles, preferably pieces of expanded structural honeycomb material, may be carried under the feeders by a movable, synchronized conveyor. This conveyor may have protruberances for holding the honeycomb material expanded during filling. Unloading may be effected by raising the filled package into a confining frame in which it is then moved for deposition in a carton.
