Definitions

  • the invention relates to a paper guide in web-fed rotary printing presses according to the preamble of patent claim 1.
  • the invention has for its object to provide a device in a paper guide in a web-fed rotary printing press, which makes it possible to cover parts of a web-fed rotary printing press hidden by a paper web, such as. B. form cylinder, temporarily accessible to the operating personnel.
  • the paper guide rollers must not be attached to a lifting platform.
  • FIG. 1 An embodiment of the invention is shown in the drawing and will be described in more detail below. It shows a printing unit with paper guide devices according to the invention in the extended and retracted positions, but without side frames on one side.
  • An offset printing unit 1 contains forme cylinder 2 and blanket cylinder 3 in its upper printing unit. B. be accessible for placing printing plates and must not be covered by paper webs 4 during this activity.
  • a paper web 4 is guided through a printing unit 10 during printing via paper guide rollers 5 to 8 fixed to the frame and a pivotable paper guide roller 9.
  • the upper forme cylinder 2 is not accessible to the operator for reasons of paper web management.
  • the last paper guide roller 9 before the feed of the paper web 4 into the printing unit 10 is mounted in a paper guide roller pivoting device 11. Their distance a from the penultimate paper guide roller 8 is dimensioned such that the pivoting device 11 can be pivoted securely through the passage space 17 in front of the printing unit 1.
  • the swivel device 11 consists of two swivel arms 12 which are positively connected to a shaft 13.
  • the shaft 13 is rotatably supported in the side frames 15.
  • the paper guide roller 8 is rotatably mounted on the shaft 13.
  • the swivel arms 12 can be pivoted with the shaft 13, that is to say about the axis of rotation 16 of the paper guide roller 8, the penultimate paper guide roller before the paper web 4 enters the printing unit 10, from a 12 o'clock position to a 6 o'clock position. Hydraulic or pneumatic cylinders or geared motors can be used for this.
  • the upper part of the swivel arms 12 is each provided with a shoulder 18, in each of which a support pin 19 of a platform 14 is mounted.
  • the platform 14 can be brought into a horizontal position and can be walked on by the operator.
  • the paper web 4 (loops), which is passed between the two paper guide rollers 7 and 8 and on the other hand between the paper guide roller 9 and the platform 14, is moved away from the forme cylinder 2 so that it is accessible to the operating personnel.
  • the platform 14 can be provided with a paper web deflection roller 20 on the side facing the paper web.
