A corrugated cardboard plant comprises at least one device for producing a respective corrugated cardboard web laminated on one side; a lamination web dispensing device; a lamination web printing device disposed downstream of the lamination web dispensing device; and a device, disposed downstream of the lamination web printing assembly, for producing a corrugated cardboard web laminated on two sides from the at least one corrugated cardboard web laminated on one side and from a lamination web. The at least one device for producing a respective corrugated cardboard web laminated on one side is configured and/or disposed in such a manner that the at least one corrugated cardboard web laminated on one side, at least in a manner adjacent upstream of the device for producing a corrugated cardboard web laminated on both sides, has a respective upwardly directed corrugation. The lamination web in the device for producing a corrugated cardboard web laminated on two sides is guided in such a manner that said lamination web therein runs above the at least one corrugated cardboard web laminated on one side.

The invention relates to a corrugated cardboard plant for producing corrugated cardboard. The corrugated cardboard plant comprises at least one device for producing a respective corrugated cardboard web laminated on one side from a respective cover web and a respective material web; a lamination web dispensing device for dispensing a lamination web; a lamination web printing assembly, disposed downstream of the lamination web dispensing device, for imprinting the lamination web; and a device, disposed downstream of the lamination web printing assembly, for producing a corrugated cardboard web laminated on two sides from the at least one corrugated cardboard web laminated on one side and the lamination web.

There is provided a system 1 of manufacturing a corrugated board, including: a corrugated-shape processing apparatus 4 for processing a board in a corrugated shape by curving the board; a shaping apparatus 5 for adjusting a corrugated board acquired by processing the board in a corrugated shape; and a stabilizing apparatus 6 for stabilizing the corrugated board being shaped in the corrugated shape, the corrugated-shape processing apparatus 4 including a first pressing jig 25 and a second pressing jig 27 each of which is in a roller-like shape provided on its surface with asperities to press a board into a corrugated board, being disposed facing each other, the shaping apparatus 5 including: a third pressing jig 45 and a fourth pressing jig 48 each of which has a surface with asperities in which a distance between adjacent apexes of the asperities is substantially identical to that of a surface with asperities of the corrugated board; and a heater 59, the stabilizing apparatus 6 including a fifth pressing jig 65 and a sixth pressing jig 68 each of which has a surface with asperities in which a distance between adjacent apexes of the asperities is substantially identical to that of a surface with asperities of the corrugated board after the heat-press process; and a cooling unit 69. As a result, a single board can be processed in a corrugated shape and a state of the corrugated shape can be maintained.

In one example of the disclosure, a print agent is applied upon a length of web substrate. A dryer is utilized to dry the web substrate length. Moisture is applied to the web substrate length. The moisturized web substrate length is wound upon a spool to form a top liner length, with no dryer to be utilized to dry the web substrate length between the moisture application and the winding.

The invention relates to a corrugated-board machine for manufacturing corrugated board. The corrugated-board machine comprises a material-web output device for outputting a material web, an inkjet printing device disposed downstream of the material-web output device for the imprinting of at least one imprint onto the material web and an overcoating arrangement disposed downstream of the inkjet printing device for overcoating the printed material web at least in regions.

A sheet heating apparatus include a first heating plate, a second heating plate, a joining member, a heating section, and a guide member. The first heating plate has a first heating surface curved in a convex shape. The second heating plate has a second heating surface curved in a convex shape. The joining member integrally joins the first heating plate and the second heating plate together such that the first heating surface and the second heating surface face outward. The heating section heats the first heating plate and the second heating plate. The guide member guides a sheet such that the sheet comes into contact with the first heating surface and the second heating surface.
