Abstract: To permit access to accessory apparatus, such as inkers or dampers, or parts thereof, through an opening in the side wall of the printing machine which is so small, for reasons of printing machine stability, that normal access thereto is impaired, at least part of the accessory apparatus is located on a slide carriage (27) which is supported similar to a suspension slide on a carriage support rail (28). The carriage support rail (28) is secured to one side wall with a pivot hinge, so that it can be pivoted laterally, horizontally, to remove the part of the accessory apparatus by sliding it outwardly on the slide carriage. A holder extension (39) slidable on the support (38) is secured to the other side wall (1) of the printing machine supports the carriage support rail and provides an end stop for the accessory apparatus when the carriage support rail is swung outwardly.
