Honeycomb insulating panels

摘要

A honeycomb panel is manufactured by placing a lower facing 2 on a lay down bed. The lower facing 2 is a continuous sheet of a flexible material which is delivered onto the lay down bed. A honeycomb core 3 is then placed on top of the lower facing 2. The honeycomb core 3 may be of any desired lightweight material such as of paper or aluminium having a plurality of individual cells 4. The lower facing 2 carrying the honeycomb core 3 is advanced along the lay down bed 2 to a lay down poker 5 which is traversed across the top of the honeycomb core 3 to evenly introduce liquid foam reactants into the individual cells 4 of the honeycomb. A top facing 10 is then placed on top of the honeycomb core 5 containing the liquid foam reactants to form a honeycomb sandwich. The sandwich thus formed is then heated in an oven 20 so that the foam expands to fill the cells of the honeycomb core to form a honeycomb panel.
