Abstract
The present invention provides a corrugated sheet manufacturing apparatus (1) which includes a single facer (8), a double facer (14), and a cutter machine (16). The single facer includes a flute pitch calculation unit for calculating and setting a value of the flute pitch of the medium in such a manner that the given cut length for the double-faced corrugated sheet becomes equal to an integral multiple of the flute pitch of the medium; a flute pitch detection unit for detecting a flute pitch of the single-faced corrugated sheet; and a brake controller (44) for adjusting a tension of a liner being fed into the single facer to allow the detected flute pitch of the single-faced corrugated sheet to become equal to the set flute pitch.
