DOUBLE FACER, AND, PASTING METHOD AND PASTING APPARATUS FOR THE SAME

摘要

A swing roll 36 is arranged over a gluing roll 14 and is configured to be movable in the direction of the arrow, so that the number of flute tips of a single faced corrugated cardboard k that are to be concurrently in contact with the gluing roll 14 at a nip N between the gluing roll 14 and a pressure roll 20 can be adjusted, and an amount of glue to be applied to each flute tip m of the single faced corrugated cardboard k can be optimized. In addition, since the pressure roll 20 is arranged on the same horizontal level as the gluing roll 14, influence of a bend caused by the weight of the pressure roll 20 can be avoided and the glue can be applied evenly in the width direction. The single faced corrugated cardboard k is wrapped around the pressure roll 20 at the exit of a nip N to allow a splash s of glue to return to a glue bath 12. Additionally, this configuration makes the single faced corrugated board to leave the surface of the gluing roll at a constant point d.
