Abstract

Curved panels made by external heating and gross reshaping of prefabricated panels comprising two flat sheets separated by intermediate partitions or bridging pieces. Heat input is controlled to soften the outer sheets sufficiently for vacuum forming without weakening the internal spacers. The heated platens used to warm the surface may incorporate ancillary ribs to cause divisions or collapse of the bridge structure to form hinge zones or panel subdivisions. Esp. for mfr. of undulating hollow panels which may be laminated in a running or crossply fashion with similar undulating or flat panels to make various packaging or insulation structures of e.g. ethylene-propylene copolymer.
