ABSTRACT:
A gravure method for applying a discrete patch (12) of uniform coating to a moving web (14) includes defining a nip area (20) between a gravure roller (16) and a backing roller (22), moving the gravure roller to the nip to a precise lengthwise location on the web, and moving the gravure roller from the nip. The method is improved by controlling the speed of movement of the gravure roller to the nip, and controlling the speed of movement of the gravure roller from the nip thereby producing a discrete patch.
