Definitions

  • the invention relates to an inking mechanism for printing presses, in which each rubbing roller has its own drive for the axial rubbing movement.
  • the clutch is preferably so formed that the parts to be coupled can be rotated relative to each other in a stepless manner within 360. It is thus possible to position the commencement point and also the commencement direction of the rubbing movement, so that an optimum printed product results.
  • the arrangement according to the invention is of special advantage in an inking mechanism in which each rubbing roller is associated with the printing form in each case through only one form roller.
  • the form rollers are allocated in pairs to each rubbing r-oller, so that the paths of the ink from the rubbing roller, corresponding to a predetermined axial rubbing roller position, through the two form rollers, are of different lengths.
  • the form rollers coacting with the same rubbing roller additionally have a mutual influence upon each other when the printing form is inked in.
  • FIG. 1 is a sectional view of a drive arrangement for distribution rollers
  • FIG. 2 is an elevation view of the drive arrangement
  • FIG. 3 is a roller diagram of an inking mechanism.
  • each rubbing roller 2 and 20 On a rotating shaft 1 which is mounted parallel to the side wall of a printing press, and which rotates synchronously with a form cylinder 21, a drive for the axial rubbing movement of each rubbing roller 2, and 20, respectively, being arranged.
  • Each comprises a flanged collar 3 which carries a number of clamping discs 4 in a recess.
  • the discs may be initially slightly dished and are flattened in response to an axial pressure exerted thereupon by tightening screws 6.
  • the resulting radial extension of the discs clamps collar 3 to shaft 1.
  • Coupling or clamping discs of this kind are well known in the art and do not constitute part of the invention.
  • the collar 3 After releasing screws 6, the collar 3 can be rotated as desired on the shaft 1, the setting rings 7 and 8 securing of the collar 3 against axial displacement on the shaft 1 when the collar is released from the shaft by loosening screws 6.
  • the collar 3 has two keys 9 which are disposed diametrically opposite to each other and which engage in corresponding grooves 10 of an adjustable eccentric disc 11.
  • the eccentric disc 11 is provided with a slot 12 so that it can be displaced in radial direction.
  • the eccentric disc 11 By means of a nut 13, the eccentric disc 11 can be fixedly clamped in any position, with the interposition of a washer 14.
  • An annular member 16 secured by a disc 15 transfers the rotational movement of the eccentric disc 11 by means of a rod 17 and an angular lever 18 onto the rubbing roller 2 as an axial movement.
  • one form roller 19, which transfers the ink to the form cylinder 21, is allocated to each rubbing roller 2.
