Abstract
Articles, such as fragile, delicate semiconductor wafers, in a first carrier member are caused to pass nearly, but not quite wholly, into a second carrier member by being pushed--against gravity--thereinto. The carrier members are then subjected to a displacement, e.g. by inversion, and said articles are allowed to drop wholly into said second carrier member. The further distance travelled by the articles after rotational displacement of a housing retaining the carrier members is very small, e.g. about 2 mm.
