Abstract
A sorter for collating sheets into sets comprises a plurality of sheet-receiving bins defined by an array of movable plates and an indexing wheel for indexing the input ends of the bin plates sequentially past a fixed feed throat to align the bin openings in turn with the feed throat. Adjacent bin plates are relatively movable apart and together for varying the sizes of the bin openings and are interconnected to limit their maximum spacing. The bin plates are spaced apart opposite and at one side of the feed throat and arranged together on the other side of feed throat. The indexing wheel engages the bin plates sequentially and the bin plates are biassed away from the indexing wheel in one direction and their interconnection permits engagement thereof by the indexing wheel in opposition to the bias. The indexing wheel suitably has a discontinuous annular flange.
