The uncontrolled valve 14 'draws secondary air from the environment when one fixed size of the negative pressure is exceeded, the fixed negative pressure is always stronger than that with the controllable valve 14 set negative pressure. The controllable valve 14 is controlled so that the effort to overcome that exercised by the transport and guiding means 20 The static friction force decreases as the transport progresses is, so that neither tearing nor lifting the print carrier can be done, just tightening the surface of the Print media results.
  • FIG. 5 shows such a further variant horizontal print carrier transport.
  • Orthogonal to the guide plate 2, which has an auxiliary device 20, 20 ' is a means of transport 10 arranged, preferably a circumferential conveyor belt 10. Die Auxiliary device does not exert any counter pressure on the Print carrier.
  • This is constructed accordingly and, like the second variant, is equipped with two transport and guide means 20, 20 ', which, however, must exert a greater force under the condition of horizontal transport.
  • the letter surface is raised in relation to the letter content in the printing area on the guide plate 2, whereas the letter bottom and letter content remain essentially at the level which is predetermined by the angle of inclination ⁇ and possibly the angle of inclination ⁇ of the positioning aid device 30 '.
  • the zx transport level contacting device 30 ' can be adjusted up and down in the y direction in the conveyor belt - in a manner not shown.
  • the precontrol and acceleration are adjusted to one another in the application aid device 30 '. This adjustment is carried out in such a way that each printing medium is always brought to a predetermined parabolic trajectory P by the application aid 30 '. The printing station is reached at a point near the apex of the parabolic trajectory P.
  • controllable valves 14 and 14 ' are controlled so that the effort to overcome by the transport and Guide means 20 and 20 'exerted static friction progressive transport are getting smaller, but the Holding force for the contact of the letter surface with the guide plate 2 until printing is completed.
  • the Pre-control using the specially designed attachment aid 30 'accelerated is at a high transport speed only an order of magnitude higher suction power due to the Motor suction pump 12 to provide.
  • Auxiliary device 30 'a parabolic trajectory P with a largest Approaching the center of the guide plate. It is the controller 40 connected to sensors 7, 8 and actuators and for synchronization all transport movements are trained and programmed accordingly.
  • This device for removing dust, fibers i.a. disruptive particles from the surface to be printed be provided.
  • This device preferably reworks a vacuum cleaner principle and is via a hose, a uncontrolled valve and a filter as well as via the connector also 26 connected to the motor suction pump 12 or has one separate drive.
