Definitions

  • the object of the invention is a pressure adjusting device o! high precision which'has none of these drawbacks.
  • the impression cylinder consists of a rotatable jacket on an eccen- 80 trically journalled core, which core it rocked one -way or the other will either bring the impression cylinder nearer to, or remove it further away from the form cylinder, thereby adjustingthe degree.
  • the rocking motion is eiected by 85 means of two pneumatic cylinders, one each for eiIecting either movement.
  • Fig. 1 of the drawing is a side view of a preferred form of the device according to the invention; 40 Fig. 2 a longitudinal section thereof.
  • the printing mechanism comprises a. form ⁇ c ⁇ ylinder l, an intermediary roll 2 and an'im- ,pression cylinder, the jacket 3 of which rotates on the core 4 oi the cylinder.
  • the intermediary roll 2 are carried by a slidable frame 6 which. by means of a screw spindle 'l4 and a wormgear 9, N in the maimframe of.
  • the impression l5 cylinder 3 will be brought closer to the form cylinder if the piston I4 moves to the right, and removed therefrom if the piston I5 is moved to the right. Since the intermediary roll 2 is pressed against the impression cylinder by a spring 20, also disposed within the slidable frame 6, it will follow its every movement.
  • pneumatic cylinders instead of the pneumatic cylinders, other means such as hydraulic, mechanical or electrical means 'may be used to act on the lever Il inthe manner 25 described.
  • the pneuniaticallyA actuated adjustment device has however the advantage of being elastic, thereby preventing'undue strain on any of' the separate parts of the printing mechanism incase o1 breakage of the web and consequent $0 troubles.
  • a. cylindrical core rotatably supporting an impression cylinder and having journals eccentric relative to said impression cylinder, bearings for said journals, a two-arm 40 lever attached to one of said journals. and means connected to -the arms of said lever for pivoting the same in either direction for turning said core to thereby adjust the position of said ini-pression cylinder relative to said form cylinder.
  • said means for pivoting said lever comprises two pneumatic cylinders
  • movable pistons in said printing machine may be moved vertically within 50 wide limits torrough adjustment, or when exchangingia form cylinder of a certain diameter cylinders, and piston rods connecting saidpistons y with the arms of said twoarm lever.
