ABSTRACT:
A method of controlling the flow of glass through multiple orifices in which a plurality of closely spaced vertical plungers have cylindrical lower portions and oval upper portions. The upper portions of the plungers are engaged and supported in closely spaced side-by-side relationship in a clamping mechanism, in which each plunger is individually adjusted independently of the other plungers. The plungers are reciprocated simultaneously for controlling the flow of glass through the orifices.
