Abstract

A carrier web coated with amino resin wherein at least one surface is resinated is produced by applying a spreadable amino resin dispersion containing 70-90% by weight of amino resin and 30-10% by weight of a liquid dispersant to at least one surface of an uncoated carrier web in an apparatus comprising: PA1 (a) unwinding station for unwinding uncoated carrier webs from rotatable supply rolls, PA1 (b) means for conveying the uncoated webs comprising a plurality of cooperating pressure rolls rotatably mounted in parallel relationship, PA1 (c) a coating means for applying a brushable amino resin dispersion to the web, and PA1 (d) a belt press for compression-molding and curing the coated web.
