1. A device for providing sheet-format substrate sections (S′), comprising a roll unwinder (01) for inlet-side feeding of a web-format substrate(S) (S); at least one application device (02) for applying a fluid to a first side of the web-format substrate(S); a drying device (03; 03′; 03″) for accelerating a drying and/or curing process, downstream from the at least one application device (02; 02′); and a cross-cutting device (04), by which the web-format substrate(S) can be cut into sheet-format substrate sections (S′) and at an outlet of which these substrate sections (S′) can be provided for subsequent processing or output to a delivery unit, wherein, for formation of a barrier layer in a manner of a coating that prevents adjacent gaseous, liquid, or pasty media from entering or penetrating the substrate material, two application devices (02; 02′) acting on a same first side and formed by varnishing units (02; 02′) that apply, to the same first side of the web-format substrate (S), varnish for forming the barrier layer as the coating that prevents adjacent gaseous, liquid, or pasty media from entering or penetrating the substrate material, wherein the varnishing units (02; 02′) are provided in the substrate path of the web-format substrate(S) between the roll unwinder (01) and the cross-cutting device (04), and a drying device (03; 03′; 03″) is provided between the cross-cutting device (04) and the, viewed upstream, first-coating varnishing unit (02; 02′), and a drying device (03; 03′; 03″) is provided in the substrate path between the two varnishing units (02; 02′).
