APPARATUS AND METHOD FOR MANUFACTURING CORRUGATED PAPERBOARD

摘要

At a location between a single facer machine and a glue machine, a web of corrugated paperboard has the flutes crushed in a narrow zone longitudinally of the web. A bonding agent is applied only to the uncrushed flutes. Preprinted liners are applied to the bonding agent on the uncrushed flutes with the liners being spaced from one another by said narrow zone.
