    Abstract: Envelopes in a vertical orientation are delivered in sequence to an envelope bundling table from a sheet insertion table where sheets are inserted into envelopes. A stationary vertical wall forms a part of the envelope bundling table and the respective short ends of envelopes of a preselected bundle of envelopes successively abut it when discharged onto that table. A movably mounted vertical wall has a first deployed configuration where it is disposed parallel to the first vertical wall, between the sheet insertion table and the stationary vertical wall. When so deployed, the envelopes of a preselected bundle successively abut it and therefore do not reach the first vertical wall. Those envelopes are therefore laterally offset from envelopes of a different bundle that abut the first vertical wall. The movable vertical wall has a retracted position so that envelopes delivered to the envelope bundling table abut the first vertical wall when the second vertical wall is retracted.

For example, the items can be sorted by destination, and each output receptacle can be allocated to a particular destination. In the event that the destination of an item has not output receptacle allocated thereto, the system controller can determine whether to allocate a receptacle, or whether to recirculate the item within the circulating storage system. This possibility allows items to be grouped together within the system, until there are sufficient items for a particular destination to allow them to be handled efficiently, and in particular allows the allocation of output receptacles to destinations to be controlled efficiently.
