A system and method for producing a board product made from paper products that have embossed medium that features an improved structural profile. The improved structural profile may include a triangular flute pattern wherein each flute may exhibit a first linear leg support and a second linear leg support that each support a center apex structure. The apex may have a substantially flat portion that is configured to engage a facing. As such, the board product may further include one or more facings that are adhesively coupled to the embossed medium. Further, the apex of each triangle may also have a groove or channel for receiving an adhesive in a continuous and uniform manner.

There is provided a corrugated sheet processing apparatus (120) comprising: sheet processing equipment comprising at least feed and guide rollers for selecting, moving and supporting sheets or webs to a corrugator (136) for forming a corrugated sheet from which corrugated products (146) can be cut, at least one layer of the corrugated sheet, and thus products, being formed from a printed sheet or web; and a control system for controlling the sheet processing equipment (136) or a cutter (148); the sheet processing apparatus (136) further comprising a visual inspection unit (162) arranged for reading printed information markers provided on at least one printed sheet or web as the printed sheet or web, and thus the printed information markers to be read, pass through the corrugated sheet processing apparatus (136), or corrugator, past the visual inspection unit (162); and wherein the control system further has a data look-up table comprising either a) for the products, at least information associated with the form or type of at least one of the sheets or webs to be used in the corrugated sheet for those products (146), and associated with that information specific identifier information readable from the printed information markers by the visual inspection unit (162), whereby the apparatus (120) can identify what products will be produced downstream of the visual inspection unit, and the required settings for the sheet processing equipment or corrugator for those products, from a read printed information marker so that the sheet processing equipment or corrugator can be appropriately controlled by the control system in response to the read printed information marker, or b) at least information associated with the products (146) to be cut from the corrugated sheet, including cutter settings for the at least one cutting apparatus for those products, and associated with those settings specific identifier information readable from the printed information markers by the visual inspection unit, whereby the apparatus (120) can identify required cutter settings for the cutting apparatus (148) for the read printed information markers so that the cutting apparatus can be appropriately controlled by the control system in response to a read printed information marker to provide a change in the cutter requirements.

A fibrous mat having high modulus reinforcing fibers can be used to make a corrugated paper. The corrugated paper can be used to make a honeycomb paper. Methods of making the honeycomb paper are discussed as well.

The plant includes a single facer for the production of a corrugated board. Video cameras detect any gluing defects or other defects of the corrugated cardboard. An image processing unit and a central control unit provide information about the detected defects and can act on one or more operating parameters of the plant.

An alignment device for aligning laminating sheets in a corrugated cardboard laminator may include, one after another along a transport path of the laminating sheets in a forward feeding direction: a first transport unit configured to transport the laminating sheets at transport speed; a first acceleration unit configured to increase the transport speed of the laminating sheets; and a second transport unit. The second transport unit may include at least one first movable abutting element transverse to the forward feeding direction of the laminating sheets and configured to align the laminating sheets.
