ABSTRACT:
An apparatus and method for the continuous production of glass articles characterized by the ability to form a single sheet of glass having two layers of different compositions, double glass panels having an air space between the panels or to produce tubes having either circular or eliptical cross-sections. The apparatus and method utilizes a molding body having a trough means which may be used to divide the glass mass into two cooperating flows over the working surfaces of an upper and lower molding body portions. The glass mass flows downwardly along an outer working surface of the upper body portion onto the inner working surfaces of the lower portion. A nozzle means provided with a ceramic shell or other refractory material may be disposed in an opening provided in the bottom portion of the molding body to provide a means for forming a closed double panel of sheet glass or a tube shaped article. The configuration of the nozzle and the bottom opening in the molding body as well as the molding body as a whole may be changed according to the desired configuration of the article to be formed.
