ABSTRACT:
A continuous, fully automated and highly productive system for the production of open core elements utilizes a fluting method and related apparatus effective for providing large pitch flutes for the input webs used in forming the core elements. A wide variety of core elements can be produced for uses ranging from large light weight building panels to small light weight packing elements.
