  • Corrugator liner bonding device
    Patent number: 3962025
    Abstract: A device capable of being removably mounted on a corrugator to glue overlapping marginal edge portions of first and second liners together to obtain a liner of greater width and of commercial value when the first and second liners are so narrow in width that in the past they would have been discarded as scrap. The bonded first and second liners may be used subsequently on the corrugator to form corrugated board that is of substantially the same strength and durability as though the bonded first and second liners were a single sheet.
