Abstract
A package stream indexer device (1) for indexing a stream (S) of packages (P) being displaced thereon within a stream plane includes first and second articulated tracks (24) with live rollers (28) and corresponding lower articulated tracks (50) with depending pressure wheels (58) for maintaining packages (P) in contact with the first and second tracks (24) and within the package path defined there between within the stream plane. Each of the first and second articulated tracks (24) along with corresponding lower track (50) are each composed of a plurality of interconnected links (26,52) frictionally engaged together to allow adjustment in track orientation from one set position to another by means of dynamic movement on the tracks (24,50). The second tracks (24) respectively register upstream arid downstream of a moveable intermediate conveyor (2′) bridging an input conveyor (40) and a reception conveyor (40″ or 40′″), with the respective indexing mechanisms (1′, 1″ or 1′″).
