Claim:
Drive apparatus for a mail-processing system, comprising: a driven enclosure-collating path having conveying fingers arranged on endless, circulating conveying loops; and an inserting station at a downstream end of the enclosure-collating path, and by means of which sets of enclosures formed on the enclosure-collating path are inserted into envelopes, which are conveyed on an envelope-filling table, parallel to the enclosure-collating path, by means of an envelope-gripper chain and are held open opposite the inserting station and, once filled with the sets of enclosures, are conveyed away from the inserting station by means of the envelope-gripper chain, the drive apparatus comprising: an intermittently rotating drive shaft driving the conveying loops of the enclosure-collating path and the envelope-gripper chain, wherein the drive shaft is coupled to a drive for the enclosure-collating path and bears a first pulley of a first drive loop, which is guided downwards from a level of the enclosure-collating path and drives a second pulley, which is mounted in a substructure of the envelope-filling table and around which is positioned a second drive loop, which is guided essentially horizontally in the substructure to a corresponding third pulley, which is supported and guided in a region of the substructure in a vicinity of an end of the envelope-gripper chain, and from which a third loop leads to a fourth pulley, which drives the envelope-gripper chain by a driving chain wheel, said fourth pulley and said driving chain wheel being mounted on a shaft on the envelope-filling table, in the vicinity of the end thereof.
