Abstract This invention relates to shaping glass sheets and particularly to a mold capable of shaping glass sheets having many different outline shapes but bent to the same radius of curvature. Such molds have dimensions larger than those of a family of windows of a given radius of curvature but different outline shapes. Such molds need not be removed or replaced until such time as production requirements call for bent windows having a different radius of curvature. A specific embodiment of this invention is provided with a series of transversely extending grooves that extend completely across the entire width of the shaping mold and have sufficient width and depth to permit clear- ance for raising the mold above a horizontal path of glass sheet travel defined by spaced conveyor rolls. The grooves have a maximum width of one inch (25.4 millimeters) and are separated by a minimum distance approximating the width of said grooves. The shaping mold is preferably constructed of an alumino- silica cement with a smooth upper shaping surface that does not mar hot glass sheets.
