  • the switchable check valve is a 2/2-way valve, in one position of the ejector with the air pressure source and in the other position of the ejector is connected to the atmosphere, so in one position of the 2/2-way valve is a positive or negative pressure the air consumer and in the other position, an exposure of the air consumer with atmospheric pressure, which means at vacuum consumption an immediate reduction of the vacuum.
  • the switchable check valve may be a solenoid valve.
  • the air pressure source may be a compressed air pump or a compressed air reservoir.
  • the exemplary embodiments illustrated in the figures have an air pressure source designed as a compressed-air pump 1, from which an over-pressure air stream can be fed to one or more ejectors 3 via a 2/2-way valve 2 designed as a solenoid valve.

  • connection 7 opens radially.
  • the terminal 7 leads to the outside air, while the outlet 5 leads to one or more Blas Kunststoffskyskyern.
  • a branched supply line 14 is connected in Figure 1 to the outlet 5 of the ejector 3, each branch 21 leads to a blowing nozzle 15 designed as Blas Kunststoffskyer.
  • each branch 19 leads to the inlet 4 of an ejector 3, the outlet 5 is also formed as a blowing nozzle 15.
  • each branch 18 is fed to a 2/2-way valve 2, which together with an ejector 3 and a blowing nozzle 15 forms a structural unit.
  • each blower 15 is also individually controlled here.
  • the timing and duration of pressurization of the ejector (s) 3 with compressed air is dependent on production data, e.g. detected by sensors or manually entered into a drive unit determined.
  • Important production data are e.g. The speed of the drive of the sheet-processing machine, the type and quality and the format of each sheet to be processed.
