  • This handling device has the disadvantage that due to manufacturing technology and assembly tolerances due to the suction cups designed as rubber suction cups are sucked differently when sucking a plurality of printing plates, whereby the printing plates can be added obliquely to the respective associated suction nozzles. This can lead to problems especially when placing and threading the printing plates on a plate cylinder.
  • the invention is based on the object, in the o.g. Magazine further described handling device, so that at least partially a height level equalization of handling objects such as printing plates on the handling device is made possible, in particular when depositing the handling objects, however, a compensation of positioning inaccuracies and manufacturing tolerances is guaranteed.

  • the suction nozzles may have an oval cross-section.
  • each section has two suction nozzles mounted on a common support element, the abutment elements of the two suction nozzles of each section being connected to one another are.
  • the stop elements of the suction nozzles of the respective sections are each mounted floating together with the respective associated suction nozzle.
  • a section-dependent, formed by two stop elements stop unit or glasses at the or on the storage side of the example designed as a rubber teat suction nozzles with the latter are floatingly attached, whereby, for example. when sucking printing plates, the stop unit moves each section together with their respective suction nozzles.
  • the suction nozzles of a section can move together with their respective stop unit or glasses, thereby facilitating positioning and avoiding damage to the handling object caused by displacement of the handling object on the stop elements.
