A sectional door (20) having a plurality of panels (21,22,23,24) including, a body portion (25) of the panels spacing and joining longitudinal edges (40, 50), one of the edges (40) between adjacent panels on a first panel having a substantially concave curvilinear surface (45) in vertical cross-sect
A sectional door (20) having a plurality of panels (21,22,23,24) including, a body portion (25) of the panels spacing and joining longitudinal edges (40, 50), one of the edges (40) between adjacent panels on a first panel having a substantially concave curvilinear surface (45) in vertical cross-section, the other of the edges (50) between adjacent panels on a second panel having a substantially planar surface (52) in vertical cross-section, longitudinally-spaced hinges (65) interconnecting the first and second panels for pivotal movement. A panel (22) for sectional door (20) having a generally rectangular foam core (140, 240, 340), an inner surface (145, 245, 345) extending the longitudinal length of said foam core, and a recess (150,250,350) in the inner surface and the foam core extending the longitudinal length of the foam core. Conveyor apparatus (400, 500) for the continuous production of foam-cored door panel material (22') having a first conveyor (410, 501) having a first panel-engaging surface (426, 503) lying in a plane for engaging the planar skin on one side of the panel material, a drive assembly (415, 510) for driving the first conveyor at a selected speed, a second conveyor (402, 502) having second and third panel-engaging surfaces (451, 464; 535, 540) for engaging spaced skin surfaces (146, 146) and an offset skin surface (150), respectively, on the other side of the panel material, and a drive assembly (435, 520) for driving at least one of the second and third panel-engaging surfaces of the second conveyor at substantially the selected speed of the first conveyor.
