Definitions

  • This invention relates to an inking apparatus for platen printing presses, and more especially to a guiding device for the ink-distributing rollers of such printing presses.
  • presses of this i type the ink-distributing rollers of which are moved to and fro over the composition, these rollers are provided at their ends with guide rolls that run on rails.
  • these latter At the places of reversal of the carriage supporting said distributing roll- 0 ers these latter have, especially in the case of a larger Working speed of the press, a certain tendency to slip whereby the inking of the composition, especially of the lower portion thereof, is rendered deficient and rise to the formation of stripes is given.
  • the object of the present invention is to obviate also the just-mentioned drawback, in fact, all drawbacks hitherto experienced, and I attain the object in view, especially a slip-free running of the ink-distributing rollers, or of the guide rolls respectively, without the employment of mechanical means specially provided for said object.
  • the invention resides therein that the guide rolls of the ink-distributing rollers which run upon the guide rails are subjected to magnetic action which holds the guide rolls in continual contact with the guide rails whereby a slip-free rolling of said rolls on said rails is rendered possible.
  • guide rails themselves may be magnetic along their entire length.
  • Fig. 1 is a side-view of a constructional form of the parts concerned of a platen printing press
  • Fig. 2 is a horizontal section on line 1-1 of Fig. 1, seen in the direction from above to below.
  • 1 denotes the frame of the press and 2 is the axle on which the platen (not show) oscillates.
  • 3 denotes the composition over which the ink-distributing rollers 4 are moved up and down. When these rollers are in their uppermost position they come into contact with the ink-cylinder 5 by which they are supplied with ink.
  • adjustable rails 6 At both vertical sides of the composition 3 adjustable rails 6 are provided at the frame I, and on these rails run in known manner rolls 1 which are attached to the axles 8 of the ink-distributing rollers 4. These rollers are in known manner supported in the ends of spring-actuated rods 9 guided in arms I0 located at both sides of the frame and being turnable on an axle l I. Owing to the action of the springs (not shown) the guide rolls 1 are pressed against the guide rails 6.
  • each of these rails is a horse-shoe magnet l2 afiixed by means of screws It; the pole surfaces of these magnets constitute elongations of the respective running path for the guide rolls 1.
  • the rolls 1 run without slip when their movement is reversed so that always the same place or portion of the ink-distributing rollers 4 comes into contact with the same place or portion of the composition.
  • the inkdistributing rollers get upon the composition, the
  • the magnets are, at least in the constructional form shown by way of example, like-wise re-adjusted.
  • the magnets may be also arranged at the upper end of the guide rails 6, that is to say, at a portion shortly in front of the place where the ink-distributing rollers 4 pass onto the ink cylinder 5.
  • a guiding device for the ink distributing rollers of platen printing presses comprising, in combination, with said rollers guide rolls connected to said rollers, and guide rails for said rolls, said guide rails forming magnets so as to be able to hold the said rolls in continual contact with the guide surface so as to obtain a slip-free rolling of the said guide rolls on said rails.
  • a guiding device for the ink distributing rollers of platen printing presses comprising, in combination, with said rollers guide rolls connected to said rollers, and guide rails for said rolls, magnets so arranged as to be able to hold the said rolls in continual contact with said 3.
  • a guiding device for the ink distributing rollers of platen printing presses comprising, in combination with said rollers, guide rolls connected to said rollers, and guide rails for said rolls, magnets directly connected with said rails 5 at those places where the said rolls run with a slip and so arranged with respect to the said rolls that these latter can run over their pole surfaces.
  • a guiding device for the ink distributing rollers of platen printing presses comprising, in combination with said rollers, guide rolls connected to said rollers, and guide rails for said rolls, and magnets forming portions of said rails, substantially as set forth.
  • a guiding device for the ink distributing rollers of platen printing presses comprising, in combination with said rollers, guide rolls connected to said rollers, and guide rails for said rolls, magnets forming portions of said rails and being arranged at those places where the said rolls run with a slip, substantially and for the purpose set forth.
  • a guiding device for the ink-distributing rollers of platen printing presses comprising, in combination with said rollers, guide rolls connected to said rollers, and guide rails for said rolls, magnets forming portions of said rails and being directly connected with the other rail portions at those places where the said rolls run with a slip.
