Abstract: An apparatus method for bending channel cross-section strip or panel material in which the material is passed between an infeed roller set 10, 16, 18, an intermediate roller set 12, 20, 22 and an outfeed roller set 14, 24, 26. At least one of the rollers of each roller set has two axially spaced annular projections which define an accommodation space for the flanges of the strip material. The axial spacing between these annular projections is reduced between the infeed and outfeed roller sets to enable the panel cross-section to be retained over a wide range of panel materials and curvature.

Abstract: Apparatus for bending a light gauge, profiled, metal panel to a curved shape, including an anvil mounted on a frame and having a part-annular surface, an arm mounted for pivotal movement about the center of curvature of the part-annular surface, a roller carried by the arm at a position spaced from the center and rotatable about its own axis, so that it can roll in an arc adjacent the annular surface, a mandrel carried by the arm for movement therewith at a location between the roller and surface, the mandrel comprising a plurality of blocks each having its length parallel to the roller axis, the blocks being juxtaposed in side-by-side relation and each shaped to conform to the profile of the panel to be bent, and at least one flexible element passing through all of the blocks and loosely holding them in juxtaposed relation, but allowing slight relative movement whereby, in use, with the mandrel engaged in the profile of a panel to be bent, the mandrel acts as a shape retaining member for the profiled panel,

Abstract: A suspension device for a support, in particular a support for a fixing panel, in which a body portion is formed as an integral structure and has two laterally extending diverging arms extending from junction points on the body portions. The body portion has downwardly extending feet, which extend at least up to the junction point of the lower of the clamping arms, and the arms are provided with axially aligned apertures to receive a support bar on the panels. Locking feet are provided at the lower ends of the legs to engage in an orifice in a support member.
