ABSTRACT:
An apparatus for providing a uniform thermal history of a free-falling glass gob having a hollow, heat-resistant conveyor tube extending between the point of shear of the molten glass and the desired mold to which the glass is to be directed and having an electrical heating means associated with at least a portion of the tube which may be controlled by a control means to transfer thermal energy through the tube to the glass gobs passing within the tube, the control means being fed information received from sensing means located at selected points along the tube which is activated by infrared rays transmitted through openings in the tubing by the glass gobs, which temperature information is transmitted to the control means and integrated to determine the operation of the heating means.
