Definitions

  • the invention relates to a sheet guiding device for a sheet-guiding printing press cylinder according to the preamble of the main claim.
  • Another sheet guiding device is known from DE 3 608 795 A1. After that is before and after a printing zone the arrangement of one across the width of the sheet Blower tube known with nozzles, which have an actuating element between the bend and blow tube.
  • the blowing device 3 has the curvature of the printing press cylinder adapted hollow guide elements 4.
  • the guide elements 4 are multiple side by side, preferably spaced, over the length of the printing press cylinder analog to Bladder 3 arranged on this.
  • Each hollow guide element 4 faces the arch 1 facing contour outlet openings 5, e.g. Holes, on
  • the guide elements 4 are coupled to the blowing device 3 by each cavity a guide element 4 through a flow opening 6 with the cavity of the Blower unit 3 is connected.
  • the blowing unit 3 also has one for each guide element 4 a locking element 7 carrying actuator 8.
  • the closure element 7 is the Flow opening 6 assigned.
  • Each actuating device 8 is provided with signal connection 9, which with a controller 10, e.g. a control center.
  • the blowing unit 3 is coupled to an air supply.
  • the mode of operation is as follows:
  • the blower unit 3 is supplied with blown air from the air supply acted upon. This flows out of the cavity of the blowing unit 3 through the open ones Flow openings 6 into the cavity of each guide element 4 and passes through the outlet opening 5 flowing onto the arch 1.
  • the guiding elements 4 which extend beyond the respective format width 2 are separated from the Control 10 individually closed or opened. This is about the sheet format width 2 controlled the switching on and off of the blown air at the outlet openings 5.
  • Receives the actuating device 8 closes a corresponding signal for activation so that it can be switched off of the blown air, the closure element 7, the flow opening 6.
  • the control device 10 activates the actuating device 8.
  • the closure element 7 opens the flow opening 6 and thus gives the way for the blowing air is free, which can strike the sheet 1 from the outlet openings 5. With this, the lubrication-free sheet guidance is realized. Furthermore, the closure element 7, depending on the positioning, the throughflow opening 6 in its degree of opening design variable so that the amount of blown air is regulated. Switching off the blown air supply in the case of the guide elements 4 which extend beyond the format width 2 leads to a Calm sheet guidance on the printing press cylinder, since blowing the sheet 1 omitted and for better pressing of the sheet 1 on the impression cylinder by the force effect the blowing air flowing out.
