摘要：A sectional door (20) having a plurality of panels (21,22,23,24), one of the edges(40) between adjacent panels on a first panel having a substantially concave curvilinear
surface (45), the other of the edges (50) having a planar surface (52). The hinges include afirst hinge element (66) having a first leaf (67), a cylindrical first knuckle (72) at one edgeof the first leaf, a through slot (73) proximate the first knuckle and a second hingeelement (80) having a second leaf (85), a cylindrical second knuckle (81) at one edge ofthe second hinge element extending into the through slot and rotatable about the firstknuckle. A panel (22) for sectional door (20) having a foam core (140,240,340), an innersurface (145,245,345) and a recess (150,250,350) in the inner surface and the foam coreextending the longitudinal length of the foam core. A bracket assembly (110) for thebottom (35) of the door including, an L-shaped plate (111), a sleeve (120) for receiving ashaft (121) mounting one of the rollers (122), fasteners (115) for attaching the L-shapedplate to the lower panel and cut-outs (125) in the cylindrical sleeve positioned
substantially above the fasteners whereby the fasteners may be removed only when theshaft 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 engaging surfaces (451,464;535,540) for engaging spaced skin surfaces(146,146) and an offset skin surface (150).
