Abrégé
(EN) Corrugated cardboard blanks are cut up into strips (20) . A larg number of strips (20) are laid flat on one another to form stack (38) . The stacks (38) are led flat through a coating sta tion (44). Using a first nozzle (46), a mist of a coating mate rial (48), in particular of water glass, is applied to one sur face (39) of the stack (38) . By means of a second nozzle (4βa) the said coating material is blown through the corrugation cavi ties of the strips (20) . Kraft paper (58) or similar material i applied to the two flat sides of the stack (38) . The core (22 formed from the stack (38) and the coating material (48), to gether with the Kraft paper/s is dried in a drying device (62) and the coating material (48) is hardened. This produces core (22) of corrugated cardboard which has high strength. B bonding boards (24, 25) to the two large faces of the core (22) bending-resistant and pressure-resistant, and even multi-laye composite board or panels are formed.
