Abstract

An apparatus for advancing articles in a selected, approximately horizontal conveying direction, includes a plurality of side-by-side disposed table elements each having an upper, approximately horizontal article-supporting surface. The article-supporting surfaces together form an approximately horizontal conveying table. A first drive oscillates each table element parallel to its article-supporting surface in a motion having two motion components oriented in perpendicular, horizontal directions and a second drive vertically oscillates each table element. A first synchronizing arrangement synchronizes the horizontal oscillations in the direction of the two motion components and a second synchronizing arrangement synchronizes the vertical oscillations with the horizontal oscillations. A first adjusting arrangement adjusts the phase of the vertical oscillations with respect to the horizontal oscillations and a second adjusting arrangement individually adjusts an amplitude of the vertical oscillation of each table element.
