Abstract
A mirror mounting is described in which a plane rectangular reflecting strip is deformed along the two longer edges thereof so that it is approximately tangent to the ideal mirror while the strip remains substantially flat in the direction of its shorter edges. In the preferred embodiment of the invention, a plurality of such reflecting strips are so formed by attachment to a supporting frame using a pair of elastomeric cushion frames to embrace the longer sides of each strip while leaving the shorter sides free. Advantageously, each reflecting strip on the frame is bent in a continuous manner the full distance of its longer side. The frame is preferably a rigid array of parallel channel members each of which is adapted to receive a curved T-section angle bar having the desired curvature of the reflecting strip. The angle bars are deformed into this curvature in a separate operation while they are being attached to the channel members. Specific apparatus for deforming the reflecting strips into conformity with the curved angle bars and for attaching the strips to the cushion frames is also described.
