ABSTRACT:
A double-facer unit includes an applicator roller having a cylindrical outer surface with spaced depressions distributed relatively uniformly over the surface thereof, mechanisms for maintaining corrugation ridges opposite from the liner side of the single-face web against an arcuate portion of the outer surface of the applicator roller for applying adhesive thereto, and an adhesive container having adhesive therein exposed to the cylindrical surface of the applicator roller in the double-facer unit whereby the adhesive contained in the container is transferred to the surface of the applicator roller including into the depressions therein, a device associated with the adhesive container for scraping excess adhesive from the roller but not from the depressions whereby the adhesive remaining in the depressions is transferred to the corrugation ridges on the single-face web when in contact therewith, and mechanisms for maintaining predetermined tension on the single-face web during the time the adhesive in the depressions is in contact with the corrugation ridges, and a source of a second liner for attaching to the corrugation ridges on the single-face web.
