  • the suction table 7 in particular Grooves 28 of a first depth and orthogonal thereto grooves 29 of a second depth deviating from the first depth from a surface of the suction table 7 for guiding the slides 26, 27.
  • the grooves 28, 29 are each arranged parallel or orthogonal to one another and guide the respective slides 26, 27 parallel to the surface of the suction table 7.
  • the Fig. 7 shows a section of the suction table 7 with actuator-adjustable slides 26, 27, for example by pneumatic cylinders.
  • the slides 26, 27 are displaced by the actuators against a spring 30.
  • each slide 26, 27 can be assigned a separate spring 30.
  • the springs 30 can, for example, be supported against a common bar fixed to the suction table 7.
  • the slides 26, 27 are moved into a position by the springs 30 or held in this, in which the openings of the slides 26, 27 overlap with the suction openings 25, ie a suction effect takes place through the suction openings 25 released by the slide 26, 27.
  • the suction table 7 can be adjusted to the substrate format to be processed by the machine by independently moving at least two slides 26, 27 that can be moved parallel to one another. Several smaller substrates can also be fixed on the suction table 7 at the same time.
  • the displacement of the at least two or more slides 26, 27 or the displacement of several slides 26, 27 arranged orthogonally, ie at right angles to one another, is in particular actuatorically or remotely adjustable.
  • a respective slide 26, 27 is preferably only moved by the actuator to close the suction openings 25, so that the suction openings 25 develop a suction effect without actuation of the slides 26, 27. Alternatively, this can also be done the other way around.
