Abstract
A method and apparatus for coating non-woven and other porous webs and the like with controlled or negligible penetration into the pores by subjecting a coating carried by a surface to electron beam radiation before laminating the web to the surface carrying the coating and with a radiation dose that only partially cures the coating into a soft or tacky state such that the laminating will effect surface spreading adhesion to the web with controlled or substantially no penetration into the pores, and thereafter subjecting the laminated web and partially cured coating to greater electron beam radiation fully to cure the coating.
