Flexible edge molding for curved surfaces

A flexible edge molding comprising a metal strip with a longitudinal axis and a pair of side edges parallel thereto, a row of narrow spaced apart substantially V-shaped notches along one of the side edges, each of said V-shaped notches having a base and a pair of side walls, said side walls converging towards a point proximal the base, a thin stretchable plastic tape with a longitudinal axis stretched and then attached along the notched side edge of the metal strip, said strip bent at a first angle along a line passing below the base and proximal the point of the V-shaped notches, said bent strip forming a web having an upper and a lower margin for attachment along a curved wall and a support flange attached to the lower margin of the web extending outwardly from the curved wall for use in supporting acoustical ceiling panels or metal pans whereby the first angle is substantially the same angle along the length of the flange.
