Inking or damping device with at least one ink or colour application roller - working with further roller to form roller gap and application roller adjacent to electrode system is acted on with different voltage compared to application roller

摘要

The electrode system (10) produces an electrostatic field, which is inhomogeneous at least in part regions. The inhomogeneity of the electrical field occurs in the radial direction of the ink application roller (3). The electrode system has several electrodes (11) in approximately line formation. The electrodes (11) extend at least over the axial length of the ink application roller (3). The electrodes (11) run parallel to the rotation axis (16) of the ink application roller, and maintain a min. distance of 15 mm to the ink application roller. USE/ADVANTAGE - Printing machine. Prevents spreading of ink or colour mist.
