ABSTRACT:
A corrugated panel in which at least the central corrugated sheet is formed from an elastically deformable material such as polyethylene synthetic plastic or spring steel is disposed and secured between a pair of cover sheets. The method of forming the panel includes stretching out a first of the cover sheets and thereafter attaching the ends of the sheet to be corrugated to the first sheet while maintaining the spacing between the remainder of the sheet. This forms a half sinusoidal shape from the sheet to be corrugated. A compressive force is thereafter applied to the sheet to be corrugated which forms it into a number of corrugations having ridges and furrows. The furrows are bonded to the base sheet and a third sheet is positioned on and bonded to the ridges of the corrugated sheet.
