Abstract: Apparatus and method for forming an elongate panel having a two-dimensional sectional profile into a curved configuration is disclosed. A pair or juxtaposed feed rolls compress the panel between them and advance the panel. A curving roll is located proximate and downstream of the feed rolls. The curving roll has a surface conformed to the outside surface of the panel, and is located in the path of the panel as it exits the feed rolls to bend the panel into a curved configuration. An anti-distortion roll is juxtaposed to the curving roll. The anti-distortion roll has a surface conformed to the inside surface of the panel, and the panel is compressed between the curving roll and the anti-distortion roll. The combination of the curving roll, the anti-distortion roll, and feed rolls cause the panel to bend about a neutral line within the panel, and the bending of the panel does not cause distortion of its side walls.

Abstract: An insulated roofing and siding system is disclosed. A plurality of elongate insulation bins are located side by side on the roof or wall of a supporting structure. Each bin has a flat base and vertical side walls defining a cavity in which insulation material can be inserted. A plurality of elongate plates are located over the respective bins, and the edges of the plates snap into incurved portions on the associated bins to enclose the cavities which contain the insulation material. Each plate has an upwardly directed flange at each of its lateral edges having an outwardly directed C-shaped section juxtaposed to adjacent such sections on adjoining plates. A plurality of discrete clips attach the insulation bins and plates to the supporting structure. Battens are snapped over adjacent flanges on contiguous lateral edges of the plates to provide weatherproofing for the roofing and siding system.

Abstract: A roofing and siding system is disclosed. The system includes a plurality of elongate, generally planar sheets each having upwardly projecting flanges disposed along the lateral edges of the sheet. The flanges each have an outwardly directed C-shaped cross section. The sheets are placed side-by-side so that the lateral edges thereof are juxtaposed to corresponding lateral edges of adjacent sheets to provide a surface comprising the exposed surface of a building. Clips are provided for attaching the planar sheets to the building. A plurality of elongate battens are provided which are constructed of resilient material. Each batten has a generally rectangular cross section including two longer, substantially parallel sides and two relatively shorter sides. One of the shorter sides of each batten is slit so that the batten can be snapped over adjacent flanges on juxtaposed lateral edges of two of the planar sheets to provide weatherproofing at the edges.
