Definitions

  • a plate clamping device with a single clamping shaft is shown in DE-GM 84 13 364.
  • the clamping shaft is arranged in a known manner in an axially parallel pit on the circumference of a plate cylinder.
  • a torsion bar spring is provided to generate a tensioning force, so that a deflection of the tensioning shaft in a clockwise or counterclockwise direction Deflection of the tension shaft in clockwise or counterclockwise direction always takes place against the force of the torsion bar spring.
  • the tensioning shaft has two opposing slots above its axis of rotation, into which an angled start or end of a pressure plate can optionally be hung. In its mouth part, the pit has two mounting edges fixed to the plate cylinder for receiving the beginning or end of the printing plate.
  • the cylinder pit 5 shows a third exemplary embodiment in which the pit 5 for receiving the clamping device is incorporated directly into the plate cylinder 1.
  • the cylinder pit 5 is rectangular in cross section and has two hanging edges 10 in the mouth part; 10.1 on which the folded leading or trailing edge 7; 8 of the pressure plate 9 can be hung.
  • In the middle of the cylinder pit 5 is a narrow clamping bar 33 z. B. 6 mm thick by means of two cylinder bolts 34 pivotally supported at their ends in bearing blocks 36.
  • the two cylinder bolts 34 are each in a horizontal bore 37 in both end faces 38 of the clamping bar 33.
  • the bearing blocks 36 are arranged at the ends of the cylinder pit 5.
  • the bent front edge 7 of the printing plate 9 is inserted into the hanging edge 10; 10.1 attached.
  • the clamping bar 11 is in the direction of rotation of the plate cylinder 1 by means of z. B. pivoted a lever pin 54.
  • one end of the lever pin 54 is inserted into the bore 53 of the clamping bar 33 and pivoted by hand in the direction of rotation until the poles 62 of the bar magnet bear against the pit cylinder wall 6.1. In this position, the magnets 59 then hold the clamping bar 33.
  • the rear edge 8 of the pressure plate 9 can be hooked into the recess 51 of the clamping bar 33 which is opposite to the direction of rotation of the plate cylinder 1.
  • permanent magnets 24; 24.1 used.
  • electromagnets all parts such as side walls 6; 6.1 or tensioning strips 12; 12.1; 33, the poles of the magnets 24; 24.1; 59 are made of ferromagnetic material or at least coated with it.
