ABSTRACT:
A coating feed apparatus and method (10) for depositing a uniform overflow curtain-like layer of coating composition (c) to a gravure surface (14) has a reservoir (14) and means for delivering the coating composition to the gravure surface (14). The reservoir (14) has a base (24) sloped upwardly from a rear wall (22). A widthwise lip (40) is directed generally downwardly towards the gravure surface (14). Widthwise lip (40) and the undercut portion (48) together enable the coating composition (c) exiting the outlet end (26) of the reservoir (12) to overflow downwardly across widthwise lip (40) in a uniform curtain-like layer (32) towards the gravure surface (14) without creating a backflow of coating composition along the base (24).
