ABSTRACT:
A new process of adhesive-coating which makes it possible to increase the adhesion of glass fibers to rubbers based on natural rubber. The fibers are impregnated by means of a composition consisting or consisting essentially of a solution containing a resorcinol/formaldehyde resin, a natural latex, a latex based on vinylpyridine and, preferably, ammonium hydroxide, and while passing through the coating bath they are subjected to vibratory movements communicated directly to the fibers. The glass fibers adhesive-coated in this way are of great interest to the rubber industry in the manufacture of tires, conveyors, conveyor belts, hoses and the like.
