摘要
Structural honeycomb material is expanded to the open, hexagonally cellular state, by pulling it out in the expansion direction. It is then compressed across the expansion direction and fed through a throat where it undergoes further compression which creases the constituent material. On being allowed to re-expand, the material adopts a stable open-cellular state. The feeding of the material through the throat is accomplished by driving means which engages the material across the expansion direction. This is an improvement on feeding it between driving rollers having rotational axes parallel with the major axes of the cells. Satisfactory compression in the throat is more easily obtained, especially with small cell-sizes.
