Reverse roll coating is a roll-to-roll coating strategy for wet coatings. It is separated from other roll coating systems by having two reverse-running nips. The metering roll and the applicator roll turn in inverse directions with the rate contrast of 50% to150%, with an exact crevice between them. The surface of the applicator roll is stacked with an overabundance of coating before the metering nip, so its surface rises up out of the metering nip with an exact thickness of coating equivalent to the crevice.
