<p>In the case of a mail-processing machine, a straightforward construction of the drive for the different machine parts is achieved in that the upwardly and downwardly directed pivoting movements of a pivoting-arm arrangement (30,31), on which a pressure-exerting roller bar (26) interacting with an envelope-conveying belt (25) is retained, are transmitted, via a coupling rod and an actuating lever, to a pivoting shaft on which a pivoting-lever arrangement is located, the bottom ends of the latter bearing spring-loaded auxiliary push-in fingers (10). Since the actuating movements of the pivoting-arm arrangement are produced by cams seated on a drive shaft, and this drive shaft also bears the chain wheels for driving a conveying-chain arrangement by means of which enclosures or sets of enclosures which are to be inserted into envelopes are delivered into the envelope-filling station perpendicularly to the running direction of the envelope-conveying belt, and this drive shaft is also in drive connection with a crank mechanism for the push-in arrangement, the drive systems as a whole can be simplified to a great extent. <IMAGE></p> |
