Device for providing sheet-format substrate sections and processing web-format substrate

A machine for treating and/or processing web-format substrate(S), comprising a first machine part which comprises a roll unwinder (01) for inlet-side feeding of the web-format substrate(S), at least one application device (02) for applying a fluid to a first side of the web-format substrate(S) and a cross-cutting device (04) for cutting the web-format substrate(S) into sheet-format substrate sections (S′), and comprising a second machine part, which immediately follows the first machine part and includes a substrate path leading the substrate sections (S′) through the second machine part, at which the substrate sections (S′) emerging from the cross-cutting device (04) are transferred inline and which, on an outlet side, leads into a delivery device (06) in which substrate sections (S′) treated and/or processed in the machine can be received;

• the machine, in the substrate path of the first machine part between the cross-cutting device (04) and, viewed upstream, the only or first application device (02;
• 02′), comprising a drying device (03;
• 03′;
• 03″) for accelerating the drying and/or curing process;
• in the first machine part, 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 the 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, the varnishing units (02;
• 02′) being 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″) being provided between the cross-cutting device (04) and the, viewed upstream, first varnishing unit (02;
• 02′) and a drying device (03;
• 03′;
• 03″) being provided in the substrate path between the two varnishing units (02;
• 02′);
• and, in the substrate path between the cross-cutting device (04) and the delivery device (06), one or a plurality of sheet printing mechanisms (08;
• 09) being provided, by which a print image can be printed on the substrate sections (S′) on a second side thereof, located opposite the first side.

A method for treating and/or processing web-format substrate(S), wherein the web-format substrate(S) is unwound from a substrate roll (11) storing the substrate(S) and provided with a barrier layer that prevents adjacent gaseous, liquid, or pasty medium from entering or penetrating the substrate material on a first side, which in a product later forms a rear or inner side, in that

• a varnish forming the barrier layer is applied multiple times onto the first side of the web-format substrate(S), which in the product later forms the rear or inner side, over a full surface or at least a large surface area, that is, on an entire or at least 80% of a multiple-up surface of the substrate(S), by way of a plurality of application devices (02;
• 02′) formed by varnishing units (02;
• 02′), in a total layer thickness of at least 5 μm;
• the web-format substrate(S) to which the varnish has been applied, downstream from each varnishing unit (02;
• 02′), is at least superficially dried and/or cured by at least one drying device (03;
• 03′;
• 03″) accelerating the drying and/or curing process, at least in a region of varnish application;
• the web-format substrate(S) to which the varnish has been applied, including the at least superficially dried and/or cured varnish, is cut into substrate sections (S′) by a cross-cutting device (04);
• and
• and the substrate sections (S′) are combined downstream in a delivery device (06) to form one or a plurality of piles (13).
