The　non-isothermal　couple　stress　fluid　inside　a　reverse　roll　coating　geometry　is　considered.　The　slip　condition　is　considered　at　the　surfaces　of　the　rolls.　To　develop　the　flow　equations,　the　mathematical　modelling　is　performed　using　conservation　of　momentum,　mass,　and　energy.　The　LAT　(lubrication　approximation　theory)　is　employed　to　simplify　the　equations.　The　closed　form　solution　for　velocity,　temperature,　and　pressure　gradient　is　obtained.　While　the　pressure　and　flow　rate　are　obtained　numerically.　The　impact　of　involved　parameters　on　important　physical　quantities　such　as　temperature,　pressure,　and　pressure　gradient　are　elaborated　through　graphs　and　in　tabular　form.　The　pressure　and　pressure　gradient　decreases　for　variation　of　the　couple　stress　parameter　and　velocity　ratio　parameter　K.　While　the　variation　of　the　slip　parameter　increases　the　pressure　and　pressure　gradient　inside　the　flow　geometry.　Additionally,　flow　rate　decreases　for　the　variation　of　the　slip　parameter　as　fluid　starts　moving　rapidly　along　the　roller　surface.　The　most　important　physical　quantity　which　is　responsible　for　maintaining　the　quality　of　the　coating　and　thickness　is　flow　rate.　For　variation　of　both　the　couple　stress　parameter　and　the　slip　parameter,　the　flow　rate　decreases　compared　to　the　Newtonian　case,　consequently　the　coating　thickness　decreases　for　the　variation　of　the　discussed　parameter.
