Reverse Roll Coating Machine

Reverse roll coating is a roll-to-roll coating strategy for wet coatings, most widely used in the coating of various thin films onto a range of substrates. It is distinguished from other roll coating systems by having two reverse-running nips. The metering roll and the applicator roll turn in opposite ways with the rate contrast of 50% to 150%, 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.
In reverse roll coating, the coating material is assessed onto the applicator roller by accuracy adjusting of the hole amongst the upper metering roller and the application roller beneath it. The coating is "wiped" off the application roller by the substrate as it goes around the bolster roller at the base. The chart delineates a 3-roll reverse roll coating process, despite the fact that 4-roll forms are normal.
