Flats bundle collator
First Claim
1. A method of stacking flats mail having bound edges a and opposed unbound edges comprising the steps of:
- transporting the flats mail along a conveyor with a major face thereof supported on the conveyor and all unbound edges facing a same side of the conveyor;
tilting the flats mail toward said planar surface to thereby direct the unbound edges of the flats mail against the planar surface;
edge-justifying the unbound edges by aligning the unbound edges against a planar surface; and
placing the edge justified flats mail into a vertical stack with the unbound edges aligned on one side of the stack.

Abstract
A method and an apparatus for collating a plurality of groups of mail items, such as flats mail, each group being pre-sequenced according to prioritized delivery addresses, into a final sequenced set of the mail items from the groups, utilizing the prioritized delivery addresses. Each bundle of mail items is formed into a single input stream of the individual mail items. The mail items are transported along a conveyor system from the input stream to a staging station. The mail items are sorted at the staging station into a plurality of subsets of mail items re-sequenced as an intermediate step to achieving the final sequenced sets. The mail items are then collated and merged into a single output stream from the respective subsets of mail items in the final sequenced set. Portions of the output stream from the staging station are collected in batches having justified unbound edges which maintain the sequence consistent with the prioritized delivery order sequence of the mail for a given carrier route.

15. A method of stacking flats mail having bound edges and opposed unbound edges comprising the steps of:
-
edge-justifying the unbound edges by aligning the unbound edges against a planar surface; and
placing the edge justified flats mail into a vertical stack with the unbound edges aligned on one side of the stack, wherein said planar surface is defined by a back wall of a C-shaped channel.
