摘要：A sectional door (20) having a plurality of panels (21, 22, 23, 24), one of theedges (40) between adjacent pannels on a first panel having a substantially concavecurvilinear surface (45) the other of the edges (50) having a planar surface (52). Thehinges include a first hinge element (66) having a first leaf (67), a cylindrical first knuckle(72) at one edge of the first leaf, a through slot (73) proximate the first knuckle and asecond hinge element (80) having a second leaf (85), a cylindrical second knuckle (81) atone edge of the second hinge element extending into the through slot and rotatableabout the first knuckle. A panel (22) for sectional door (20) having a foam core (140, 240,340), an inner surface (145, 245, 345) and a recess (150, 250, 350) in the inner surface andthe foam core extending the longitudinal length of the foam core. A bracket assembly(110) for the bottom (35) of the door including, an L-shaped plate (111), a sleeve (120) forreceiving a shaft (121) mounting one of the rollers (122), fasteners (115) for attaching theL-shaped plate to the lower panel and cut-outs (125) in the cylindrical sleeve positionedsubstantially above the fasteners whereby the fasteners may be removed only when the

shaft is not positioned in the cylindrical sleeve. Conveyor apparatus (400, 500) for thecontinuous production of foam-cored door panel material (22') a second conveyor (402,502) having panel engaging surfaces (451, 464, 535, 540) for engaging spaced skin surface(150).
