ABSTRACT:
The forming surface of a forming mold (5) for postforming of a shaped cord (2) in the shape of a frame extruded onto a glass (1) is slightly curved in the direction of the length of shaped cord (2). In the final position of forming mold (4) during the postforming operation, lateral edges (11, 12) are thus slightly above the surface of shaped cord (2). This avoids the creation of imprints in the form of lines or edges on the shaped cord, and a smooth transition is achieved between the postformed length of the shaped cord that attaches there.
