  • This air curtain can be formed by a plurality of successively arranged blowing nozzles or preferably by a substantially continuously extending, in particular formed of an aluminum extruded profile slot nozzle. Due to the relatively short gap height to be bridged by the air curtain, this approach results in a particularly effective partitioning off of the lead-through area provided for the test sheet removal.
  • the air supply device provided for supplying compressed air to this blowing device is preferably designed so that during the removal of a test sheet the blow-off of the compressed air can be temporarily prevented so that the printed sheet is not unduly pushed out of its removal path.

  • This tuning can be done in particular by small orifices and adjusting plates, through which the effective passage cross-section can be adjusted as needed in certain areas of the Heilabgriffs arthritis.
  • the windscreen is also possible to design the windscreen as a double-wall structure, so that a windscreen interior is generated by this double-wall structure, which acts directly as a suction channel.

  • the lower, second Heilabgriffs issued 2 shown here is located in this embodiment immediately adjacent to a front transverse edge K of a below the windscreen 4 and thereby below a test sheet tapping space PB downwardly extending protection 5.
  • the first Gutabgriffs coupled 1 comprises a transverse channel 6, which extends below the windshield 4 approximately at the level of a lower running plane E of a gripper chain 7.
  • the transverse channel 6 is designed such that it has a rectangular cross-section in a sectional plane perpendicular to the deflection axis X of the gripper chain 7.
  • the transverse channel 6 is formed by a frame element which forms part of a front window device 4, which is movably articulated via a four-bar linkage.
  • the connection of the transverse channel 6 to a corresponding Beerabsaugsystem can be accomplished so that over the transverse channel 6 in the unfolded position indicated here, further air from the front of the boom can be sucked, so even in the open state, at least a significant portion of the contaminated air does not escape into the environment of the boom, but still can be tapped through the transverse channel 6 and optionally further extraction structures.
  • the windshield 4 is also possible to design the windshield 4 as a double-wall structure, so that between an outer disk 4a and an inner disk 4b of the same a windscreen interior is formed, which acts directly as a suction channel.
  • the second, located below a test sheet tapping space PB Vietnameseabgriffs Republic 2 is formed by an upwardly open channel structure.
  • This gutter structure can be designed as a bending or extruded profile and in this case be incorporated into the protection 5 as a corresponding structure.
  • the derivative of the air taken up by this channel structure is preferably carried out in the lateral region of the boom.
  • corresponding Heilabgriffsö réelleen are provided for this purpose in both side regions of the jib, which come into contact with the frontal passage cross sections of this gutter structure, so that the per se functional Beerabgriffssystem is provided immediately after applying the Verschutzung 5, without here to a special connection of Heilabgriffs worn by manually to be applied pipe or hose structures required.

  • This air curtain 11 By means of this air curtain 11, a particularly effective partitioning of the air located in the area of the sample sheet removal area PB from the outside environment of the boom is achieved.
  • This blowing nozzle device 10 may be formed by a pipe structure which preferably has a plurality of slot nozzles extending in the longitudinal direction of the pipe structure.
  • this upper blowing nozzle device 10 is accomplished in such a way that the air curtain generated by this 11 flows particularly effectively and reliably into the lower Heilabgriffs issued 2 and this supports by Mitr 1969 citrate a particularly reliable discharge of the partial air flow T2 in the lower Heilabgriffs worn 2.
