Abstract
Method and apparatus for the coating of liquids, particularly of colour markings, onto film webs or the like. A printing unit (16) serves for the transfer of especially small colour markings to film webs. In the printing unit (16), a dye roller (25) dips from above into a dye chamber (24) which is open at the top and takes up dye by means of a rotating movement. This dye flows constantly or intermittently through the dye chamber (24) which is dimensioned to be relatively small. The dye can be fed to the dye chamber (24) from a reservoir (43) via a feed conduit (45) or discharged from the dye chamber (24) to another reservoir via a discharge conduit (46). A further particularity consists in measures for the improvement of the proofness by sucking off dye residues on the dye roller (25) by means of suction conduits (74, 76).
