  • Publication number: 20170342655
    Abstract: A process for coating a fabric web on upper and lower sides in one pass containing unwinding a fabric web, coating the upper side of the fabric web with a upper coating composition using a first coater, coating the lower side of the fabric web with a lower coating composition using a second coater, drying the coated fabric web in a horizontal dryer, and winding up the coated fabric web. The upper and lower coatings are each in an add-on amount of between about 10 and 75 GSM. The second coater comprises an entry edge and a beveled exit edge, where the entry edge is located closer to the first coater than the beveled exit edge, the entry edge of the second coater is in contact with the lower side of the fabric web, and the beveled exit edge of the second coater is not in contact with the web.
