A corrugating machine for forming corrugations in a paper medium and applying a liner to the tips of the corrugated medium to yield a single faced corrugated paper product, comprising an elongated fluted roller supported at its opposite ends for rotation about a roller axis, a plurality of discrete forming rollers disposed at separate locations spaced along the length of said fluted roller, with each of said forming rollers being individually supported for rotation about its own distinct axis of rotation spaced from said roller axis and having flutes operative to intermesh with the flutes of said fluted roller and to cooperate therewith to form corrugations in said medium as said medium is passed between said fluted roller and said forming roller, and a plurality of discrete smooth surfaced pressure rollers disposed at separate locations spaced along the length of said fluted roller, with each of said pressure rollers being individually supported for rotation about its own distinct pressure roll axis spaced from said roller axis and with its peripheral surface disposed adjacent the periphery of said fluted roller for accommodating said medium and said liner as they are passed between said fluted roller and said pressure roller.

A corrugating machine for forming corrugations in a paper medium having upper and lower corrugating roller assemblies which cooperatively define a medium entry location and a medium exit location and which are operative to form corrugations in a paper medium passed between said entry location and said exit location, with said lower corrugating roller assembly being comprised of an elongated fluted roller supported for rotation at its opposite ends, and said upper corrugating roller assembly comprising a plurality of discrete fluted forming roll segments of different diameters supported for rotation at separate stations spaced along the length of said fluted roller, with each of said forming roll segments cooperatively defining with said lower corrugating roller a distinct nip centerline disposed at a location between said entry location and said exit location and through which a portion of said medium passes.

A corrugating machine for forming a corrugated medium and applying a liner to said corrugated medium to yield a single faced corrugated paper product comprising an upper corrugating roller assembly, a lower corrugating roller assembly which cooperates with said upper corrugating roller assembly to form said corrugated medium, and a pressure roller assembly which cooperates with said lower corrugating roller assembly to define an entry location and an exit location through which said corrugated medium and said liner are passed and between which said liner is applied to said corrugated medium, with said pressure roller assembly comprising a plurality of discrete pressure roll segments of different diameters supported for rotation adjacent said lower corrugating roller assembly at separate stations spaced along the length of said lower corrugating roller assembly, with each of said pressure roll segments cooperatively defining with said lower corrugating roller assembly a distinct nip centerline disposed at a location between said entry location and said exit location and through which a portion of said corrugated medium and said liner pass.
