PROBLEM TO BE SOLVED: To provide a single-faced corrugated web manufacturing apparatus capable of bonding a liner web and a corrugated intermediate web by adhesive without using a pressure roll nip. SOLUTION: A bonding roll 17 to be heated having a grooved outer surface supports a single-faced corrugated web 14 on its peripheral part to form an uncured bond to an adhesive layer before the single-faced corrugated web 14 is separated from the bonding roll 17. The bonding roll 17 is internally heated to heat the single-faced corrugated web 14 or a steam chamber is arranged in close vicinity to the lower part of the bonding roll 17 to introduce steam in the contact state of the single-faced corrugated web 14 with the outer periphery of the bonding roll 17 to heat the single-faced corrugated web 14. |
