Abstract:
1. A process of coating a paper web on both its sides with a film coater having two applicators, a pair of rolls for coating the paper web, the two applicators applying coatings to the surfaces of the pair of rolls, the process comprising the steps of forming a nip with the pair of rolls, applying coating to each of the two rolls with the two applicators, running a web through the nip in an upward direction, transferring coatings from the roll surfaces to each of the sides of the web at the nip, separating the web from the rolls and creating film split droplets or mist, causing said film split droplets or mist to fall back onto the roll surfaces, locating two doctors above the nip for leveling coatings on both sides of the web, and leveling and smoothing the coating on both sides of the web with said two doctors for minimizing any residual film split pattern and fiber rise, whereby the web can be coated on both sides and the film split droplets falling back onto the rolls.
