Abstract
A device includes a tank for storing a glue solution; a roll having a surface for transferring the glue solution onto an area of a corrugating medium of a single-faced corrugated fiberboard sheet in the width direction; scraping members for regulating adhesion of the glue solution outside the area on the surface of the roll; a movement mechanism for moving the scraping members in the width direction; and a control device for setting, on the basis of the cutting width dimension with which the double-faced cardboard sheet is to be cut after passing the roll, the area to be a region in which margins in the width direction have been added outside positions of the side edges of the cutting width dimension, and for controlling the movement mechanism to dispose the scraping members at positions corresponding to the positions of the side edges of the glue application region.
