Abstract: 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.

Abstract translation: 在表面上限定涂布液的图案的方法包括将涂布流体引入限定在第一辊的表面和第二辊的表面之间的辊隙中。 轧辊表面在轧辊压力下在辊隙处被推动在一起，并且在辊隙中朝向涂覆流体沿相反方向移动。 在辊隙之后计量到第二辊表面上的涂布液的量是第一辊表面的形貌和辊隙压力的函数。 第一辊表面是一致的，并且第一和第二辊表面一起被推动。 第二辊表面的选定部分与刮刀接合以从其上除去涂覆液，其中涂覆流体的图案保留在由至少一条涂布流体限定的第二辊表面上。 涂布液的图案通过反向接触涂层从第二辊表面转移到移动的网。
