ABSTRACT:
A pattern table for forming of heated glass tubing such as neon light tubing according to a prescribed flat pattern. The table includes three support surfaces: a first for holding the pattern; a second light transmitting plate held directly over the pattern; and a third light transmitting screen supported on a top surface of the plate. Heated glass tubing can rest against the screen and be formed according to a pattern viewed through the screen and glass plate. The pattern is insulated from the heated glass tubing being formed. The heated glass tubing in turn is isolated from the heat absorbing glass plate by an interposed air space within the screen structure.
