PROCESS FOR APPLYING A COATING TO BOTH SIDES OF A RUNNING PAPER WEB

TITLE: PROCESS FOR APPLYING A COATING TO BOTH SIDES OF A RUNNING PAPER WEB. A continuous process for applying a coating to both sides of a paper web in which the web is fed at a speed of at least 400 metres per minute through the nip formed between a rotating applicator roll and an elastically yielding blade. A coating composition is fed into the sumps formed on each side of the web at the nip at a rate such that the amount of coating material applied to the web, calculated as the total of both sides of the web, exceeds 14 grams per square metre. The viscosity of the coating composition is maintained at 400 to 2000 centipoises and the web is withdrawn from the nip so that it is bent away from the applicator roll over the edge of the blade at an angle of between 8.degree. and 12.degree. to the tangient to the roll at the nip, thus reducing or eliminating the formation of mist downstream of the nip.
