ABSTRACT: Disclosed is a method and an apparatus for manufacturing a triple wall corrugated board by laminating two single- faced corrugated boards respectively formed by a pair of single facers in a corrugator and also by pasting a liner on one side of the single-faced corrugated board, charac- terized in that: at least one of said pair of single facers is replaced with a single facer having two sets of fluting units with different flute specifications which enables selective formation of different flute types of single-faced corrugated boards by selectively using the desired set of fluting unit; and both of the single facers are simultaneously operated with one of the fluting units with different flute specifications being selectively used so that different types of triple wall corrugated boards can be formed selectively.
