Abstract: A method for supplying and inserting document sets into associated envelopes, in which the document sets are supplied to an insert station in a document material stream and the envelopes are supplied to the insert station in an envelope material stream, to allow mail pieces to be collated with high reliability. In the insert station, the document set supplied in each case is inserted into the relevant envelope supplied at the same time, wherein for each document set, the position thereof in the document sequence and an associated document identification code are determined, and for each envelope, the position thereof in the envelope sequence and an associated envelope identification code are determined, and a document set and an envelope are supplied to the insert station only as a pair when it is confirmed that the envelope pending supply is individually associated with the document set pending supply.

Abstract: A method for supplying document sets (4) and inserting document sets into associated envelopes (2), in which the document sets (4) are supplied to an insert station (10) in a document material stream formed by a sequence of document sets (4) and the envelopes (2) are supplied to the insert station in an envelope material stream formed by a sequence of envelopes (2), said method being intended to allow the mail pieces consisting of the document sets (4) and the envelopes (2) to be collated with particularly high reliability and precision in a particularly simple manner.

Abstract: At least three storage devices (6,7,8) are serially arranged between an entrance station (1) and a processing station. Transfer devices are disposed between adjacent storage devices and between a last storage device and the processing station. The transfer devices are operated independently of each other, a given transfer device being operated whenever both a storage device which precedes the given transfer device in the direction of travel of the sets of sheets is occupied and a storage device which succeeds the given transfer device in the direction of travel of the sets of sheets is ready to receive a set of sheets.
