Abstract
A pocket for receiving and stacking sorted documents from a high-speed reader sorter includes an anti-jamming device for engaging the documents in the pocket to urge the documents into a stacked configuration according to the sequence in which the documents enter the pocket. The device includes a casing having a plurality of flexible elements projecting therefrom, such that the elements extend transversely with respect to the path of the incoming documents. A document entering the pocket will bend at least some of the flexible elements along the path of the incoming document. The flexible elements deflect the previously pocketed documents out of the path of the incoming documents, to allow the incoming document to enter the pocket unimpeded. The flexible elements are held in discrete bundles by mounting the elements in trapezoidal-shaped cavities within the casing. The flexible elements have sufficient stiffness to resist bunching and tangling at the free ends of the flexible elements, such that the integrity of the individual bundles of flexible elements is maintained and the flexible elements exert a consistent biasing force on the documents to inhibit jamming and to urge the documents sequentially into the stacked configuration.
