ABSTRACT OF THE DISCLOSURE A method of dispersing droplets of a polymerizable, cross-linkable material, in a liquid carrier, within a fibrous web, in which the material is to be polymerized and cross-linked, as a part of a method of manufacturing a composite web, which comprises the fibrous web and dispersed inclusions of the material, as polymerized and cross-linked. Droplets of the material are dispersed within the fibrous web by moving the fibrous web through a droplet-flicking zone and flicking droplets of the material, in the liquid carrier, onto opposite sides of the fibrous web as the fibrous web is moved through the droplet-flicking zone. On each of opposite sides of the fibrous web, a rotating brush has bristles, picking up the material, in the liquid carrier, and flicking droplets thereof as the brush rotates. Each brush picks up the material, in the liquid carrier, from a rotating roller wiped by the bristles of such brush. Each brush and the roller wiped by the bristles of such brush rotate, in opposite rotational senses, about parallel axes. The material is polymerized and cross-linked in situ, so as to form the composite web.
