  • Method of making drape-shaped glass element by sagging between column supports
    Patent number: 5215567
    Abstract: A method of forming a drape-shaped glass structural element are disclosed. The element may be used as a support for a glass table top. The glass element is formed by a unique method which involves initially supporting a glass sheet on both fixed and movable members within a mold. The movable members are moved after the glass has begun to soften and move to a final shape. This causes the final glass element to have a complicated shape which cannot be formed by conventional glass forming methods.
