Abstract: There is described an apparatus (1) for coating a cylinder (C), in particular a wiping cylinder of an intaglio printing press, with a plastic composition comprising inter alia heating means (6) for applying radiant heat to the cylinder throughout its length as the cylinder is rotated, the heating means including a plurality of discrete heating elements (60) distributed along the length of the cylinder and around at least part of the peripheral surface of the cylinder, the heating elements being arranged at least in separate columns (60a to 6Oh) disposed parallel to one another along the length of the cylinder. The apparatus further comprises a temperature sensing system (9) for measuring the surface temperature of the cylinder along the length of the cylinder and a processing unit coupled to the temperature sensing system (9) for controlling operation of the heating elements (60) as a function of the measured surface temperature and a desired temperature setting (tc).
