Method and apparatus of forming a coating fluid pattern

摘要

A method of defining a pattern of coating fluid on a surface includes introducing coating fluid into a nip defined between a surface of a first roll and a surface of second roll. The roll surfaces are urged together at the nip under a nip pressure and move in opposite directions toward the coating fluid in the nip. The amount of coating fluid metered onto the second roll surface after the nip is a function the topography of the first roll surface and the nip pressure. The first roll surface is conformable and the first and second roll surfaces are urged together. Selected portions of the second roll surface are engaged with a doctor blade to remove coating fluid therefrom, wherein a pattern of coating fluid remains on the second roll surface which is defined by at least one stripe of coating fluid. The pattern of coating fluid is transferred from the second roll surface to a moving web by a reverse kiss coating.
