Abstract
Abstract A door panel A,B having inner and outer skins 10 and 11, 110 and 111 and a rigid expanded core 15,115, filling the cavity between the skins with stiles 19,119 extending across the ends of the cavity, said panel being made by the method comprising continuously supplying two strips of sheet material 10c,110c and 11a,162b, spraying the under-surface of strip 11a,162b with expansible thermal insulating foam 34,134, bringing the strips together and moving them under heat and pressure in pressure conveyor F to expand the foam and fill the cavity between the strips, progressively forming marginal sealing portions 11b,160 of strip 11a,162b into sealing relation with the contoured edges 12,112 and 14,114 of the other strip at stations G and H, and shearing the moving composite strip into lengths at station I.
