Abstract
Examples include a device for providing sheet-format substrate sections from a web-format substrate. The device includes a roll unwinder for inlet-side feeding of the web-format substrate. Two application devices act on the same first side of the web substrate, and are formed by coating units for supplying, to the same first side of the web substrate, a varnish that forms a barrier layer. A drying device is provided between a cross-cutting device and an upstream first coating unit and/or the drying device is provided in the substrate path between the two coating units and the cross-cutting device. The web-format substrate can be cut into sheet-format substrate sections and, at the outlet, the substrate sections can be provided for subsequent processing or output to a delivery unit.
