Abstract

A plurality of parallel infeed conveyor belts increase in length from the shortest to the longest in length increments corresponding to the length of groups of equal numbers of containers in rows on the belts. The groups are in multiple file arrangement initially and are translated respectively to the end of each belt to effect disposing the groups in series and offset but parallel relationship. The groups are then advanced together to aligned belts of an intermediate conveyor to arrive at a conversion region wherein all groups that are offset relative to a group on one intermediate conveyor belt are shifted laterally to alignment with the one group so the formerly parallel groups become arranged in single file in condition for being conveyed further.
