  • the rubber blanket cylinder transmission 2 is driven by known drive devices, which results in the rubber blanket cylinder transmission 2, the shaft 1 and the rubber blanket BLNKT being rotated.
  • Blanket cylinder 2 is carried with a switchable image cylinder gear 3.
  • Shaft 5 of the blanket cylinder BLNKT is connected to a blanket cylinder shaft encoder 13.
  • the image cylinder gear 3 is mounted for rotation on a bearing 4, this bearing being fixed on a shaft 5 of the image cylinder P.
  • a coupling device 6 which moves along the length of shaft 5 and rotates with shaft 5.
  • the coupling device 6 comprises radially outwardly projecting wedges 7 which selectively engage in radially inwardly projecting wedges 8 on the inner circumference of the image cylinder gear 3 when the coupling device 6 is in the position shown in FIG. 2A position shown.
  • the coupling device 6 further comprises, on a side facing away from the picture cylinder P 1, radially outwardly projecting wedges 9, into the radially inwardly projecting wedges 10 on the inner circumference of a first picture cylinder auxiliary drive pulley 11 when the coupling device 6 is shown in that in FIG. 2C Position.
  • the first image cylinder auxiliary drive pulley 11 is mounted for rotation on a bearing 12, this bearing being fixed on the shaft 5 of the image cylinder P 1 .
