Abstract
An apparatus for production of a two-ply paperboard panel is provided. The apparatus comprises a supply of top paperboard panel web. A flap-cutting die cut module receives the top paperboard panel web and cuts a pattern of flaps therein. A flap-forming die roll in juxtaposition with a flap-receiving pocket roll defines an interface therebetween through which the top paperboard panel web is received. An adhesive-application station applies adhesive to surfaces of flaps formed on the top paperboard panel web. A supply of bottom paperboard panel web is provided, which is joined to the top paperboard panel web at a web-merging station. A hold-down system holds the top and bottom paperboard panel webs together while applied adhesive sets or cures. A method for producing a two-ply paperboard panel is also disclosed.
