The invention concerns a process for manufacturing corrugated board comprising two layers of corrugated medium joined together in tip-to-tip registration between the corrugations of the two mediums, without an intermediate liner, and with at least one outer liner, the process comprising feeding webs (7) of corrugating material between respective pairs of corrugating rolls (4, 5) to form the webs into corrugated mediums, applying adhesive (32, 33) to the tips of one of the mediums to permit adhesion with the tips of the other medium, and conveying the two mediums along adjacent linear paths (23, 24) with tip-to-tip registration between the corrugations of the two mediums, while applying pressure urging the mediums into contact with one another while the adhesive is caused or allowed to set at least partially, at least one outer liner (11) being applied either before or after the corrugated mediums are conveyed along the linear paths in which the tips of their corrugations are brought together. |
