ABSTRACT:
A nesting table is provided which receives containers en masse from a mass air conveyor at an upstream end and discharges the containers onto a deadplate in three rows in contiguous equilateral configuration. In one embodiment, a high air pressure zone is provided along the nesting table by means of a cover extending from one side across the table to a point spaced at least one container diameter from the opposite side so that the containers entering the nesting table form two longitudinal rows on opposite sides and fill in between with a third row which nests with the row of containers which is not under the cover. A kicker plate is provided downstream of the cover to move the three formed rows of containers into nesting contiguous equilateral configuration for movement onto a deadplate. In a second embodiment, the cover is spaced at least two container diameters from the opposite edge and tapered side guides converge the three rows of containers. A third embodiment is like the second but has a second cover extending from the opposite edge to a point spaced from the first cover to form a slot for escape of air. A fourth embodiment has a cover extending across the entire table with converging downstream edges which come to a point. A row of containers is formed along each edge and a third row beyond the pointed end.
