ABSTRACT:
The present invention comprises an apparatus for making a selectively-coated web. The apparatus comprises a coating means for applying a coating to a web in a plurality of coated regions, the coated regions being in spaced, parallel relationship to a plurality of uncoated regions. The present invention further comprises support means for supporting the web after coating, the support means comprising a plurality of support members, each of the support members being in registry with an uncoated region. In a preferred embodiment the coating of a beneficial emulsion is applied in selected regions by extrusion. A method of forming a coated web without producing buildup of coating material on idler rollers is also disclosed. The method comprises the steps of: (a) coating a web in a plurality of coated regions, the coated regions being in parallel spaced apart relationship to uncoated regions; (b) providing support members, each of the support members being aligned in registry with an uncoated region; and (c) guiding the coated web in contact with the support members such that each support member is in registry with an uncoated region of said web.
