ABSTRACT:
A single file apparatus is provided for highly etched containers wherein a mass of containers is separated into two single file rows, the single file rows are merged into nesting relationship and the nested rows of containers separated and further merged into single file. The mass of containers are separated into separate rows along each side of an air conveyor having an imperforate cover forming a high pressure area between the rows. The differential pressure in this high pressure area is lower at the upstream end than at the downstream end so that containers which move into this central area will recirculate upstream. The separated rows of containers are brought into an alignment zone and arranged in nested relationship and are merged into an equilateral triangular configuration with mutually touching side edges in a nesting section within the alignment zone. The containers then are accelerated into a high pressure buffer section of the alignment zone where they are separated from each other and converged into single file. This buffer section eliminates the possibility of transmission of upstream forces caused by engagement of the single file containers by downstream equipment so that such forces will not be transmitted back through the single file apparatus.
