Abstract: Apparatus, method and modules for sorting flat objects. The apparatus comprises a number of sorting holders, a conveying system with a switch and branches connecting thereto, a reading unit, and an object separator for feeding, one by one, stacked objects to the conveying system for recirculation. Because in operation, during the feed from the sorting holders, the objects are separated and individually recirculated from the sorting holders to the switch, this can be controlled in a simple manner and carried out with simple, compact conveying means. The apparatus can be modularly constructed from a basic module with a sorting holder and one or more sorting modules also with a sorting holder and a recirculation path.

Abstract: Method for processing sheets in a processing apparatus comprising a plurality of processing stations and a control system controlling at least one processing station for printing sheets and/or assembling sheets to form at least one document to be mailed. By means of a text unit not belonging to the processing apparatus, at least one digital document in digital form is generated, in which at least one digital code also generated with the text unit is included. This code comprises information about the manner in which the control system is to control the processing stations. The digital document is supplied to the control system in digital form, whereafter the control system records the digital document in digital form, recognizes the code and controls the processing station depending on the code.
