Abstract
A device for gluing of a double facer includes a glue bath containing glue; a gluing roll immersed in and coated with the glue; a doctor roll adjusting the glue on the gluing roll to a predetermined thickness, transferred to a single faced corrugated cardboard; a swing roll disposed at an upstream portion of a transferring direction of the corrugated cardboard; and a moving device that moves the swing roll in a direction that the single faced corrugated cardboard is wrapped around the gluing roll. The swing roll is wrapped around the single faced corrugated cardboard, and the number of flute tips of the single faced corrugated cardboard that are concurrently contacting with the gluing roll and applied with the glue is adjusted by moving only the swing roll in such a direction that crosses a sheet face of the single faced corrugated cardboard passing through the nip.
