Abstract
A lightweight outline mold for shaping glass sheets comprising a shaping rail having low thermal inertia, tabs attaching said rail to a reinforcing frame through rods by welding said rods at points spaced from said shaping rail and using fastening means that do not require localized heat, such as rivets, to attach the shaping rail to the tabs in a manner that avoids localized heating of the shaping rail during mold fabrication that would distort the shaping rail if the latter were welded directly to the reinforcing frame.
