ABSTRACT:
A device for printing stock standing on edge, in particular a piece of mail in postage meters and/or addressing machines includes a guide plate along which the stock slides. The guide plate is inclined relative to the vertical and has a recessed region for a printing device. A rotating conveyor advances the stock along the guide plate. The printing device is an ink jet printing device with at least one ink jet print head. The recessed region includes at least one cutout and a downstream region of the guide plate is so far recessed from a bearing surface for the stock that there is no contact with the latter in that location. That ensures sufficient penetration time for ink and prevents smearing of the printed image. Pressure elements with a pressure plate are fastened to the conveyor. The pressure plate is moved against spring force toward and away from the guide plate and presses the stock against the same. A friction lining fastened to the pressure plate carries the stock. The elastic mounting of the pressure plate ensures continuous adaptation to varying thicknesses of the stock. The direct coupling of the pressure elements with the conveyor and the use of an ink jet print head enables continues transport and printing. The device improves the printing technology and simplifies transport of the piece of mail. The simple construction ensures precise feeding of the stock and a clean printed image.
