Abstract (en)
[origin: EP2792478A1] A unit (1) for manufacturing corrugated board (105) from sheets of paper material (100), comprising: corrugation means (2) suitable to heat-corrugate a first sheet of paper material (101) to make a corrugated sheet(101a), heating means (3) suitable to heat sheets of paper material (100) to provide the heat needed to optimise at least the processing performed by the corrugation means (2), first gluing means (4) suitable for joining, by hot gluing the corrugated sheet (101 a) to a second sheet of smooth paper material (102) to make a compound corrugated sheet (103), second gluing means (5) suitable for joining, by hot gluing, the compound corrugated sheet (103) to a final sheet (104) to make corrugated board (105), the first gluing means (4) and the second gluing means (5) are positioned next to the corrugation means (2), so that the first heating means (3) are able to supply at least a predominant part of the heat needed by the first gluing means (4) and the second gluing means (5).
