PROBLEM TO BE SOLVED: To enable a wrapping angle to be adjustable regardless of the kind of paper and the size of a flute and the time for a single corrugated fiberboard sheet to come into contact with a gluing roll to be adjustable, in a gluing device for a corrugation machine equipped with a gluing roll which performs a gluing operation to bond a liner paper to the stepped part on one side of the single corrugated fiberboard sheet which is composed of a core paper formed in the shape of corrugation and the liner paper bonded to the flute crest part on the other side of the core paper, and a guide roll which is provided in the upstream side or the downstream side of the gluing roll and sets the wrapping angle to the gluing roll for the single corrugated fiberboard sheet. SOLUTION: The wrapping angle is made variable to a gluing roll 8 for a single corrugated fiberboard sheet by making a guide roll 21 provided in the upstream side or the downstream side of the gluing roll 8 movable as shown by a chain line. Consequently, the time for the single corrugated fiberboard sheet to come into contact with the gluing roll 8 can be adjusted in compliance with the kind of paper an the size of a flute. Thus it is possible to manufacture the corrugated fiberboard sheet of stable quality, even when operating parameters are changed.
