1. A package stream indexer device for indexing a stream of packages being displaced thereon within a stream plane, said device comprising a support section mounted on a mounting frame and including a series of live rollers mounted on an articulated track defining a shaped package path having an articulation line substantially within the stream plane, the track being formed of a plurality of interconnected links frictionally engaged together and adapted for dynamic movement for the purpose of altering the orientation of the shaped package path, each said link of the plurality of links pivotally interconnecting to an adjacent said link about an articulation axis generally perpendicular to the stream plane, and an opposite package retainer mechanism mounted on the mounting frame and being disposed adjacent and in spaced relation to the articulated track in a direction perpendicular to the stream plane for keeping packages in abutment contact with the rollers within the stream plane.
