Multiple orifice glass feed system.

摘要

A multiple orifice glass feed system for use with a glass forehearth including a plurality of closely spaced plungers (12), each of which is individually supported independently of the other. Each plunger (12) includes a servo controlled linear actuator (16) and an arm (15) extending between each plunger and its respective servo-motor. Each servo-motor has an axis parallel to the axis of the plungeres (12). An air spring (18) is associated with each plunger (12) for balancing the weight of each plunger and its respective arm. The center liens of the plungers (12) lie generally in a plane (P1,P2). The arms (15) have the major portions thereof generally parallel and closely spaced. A feedback system is provided to monitor the position of each individual plunger (12) independently of the other at all times and make corrections to the actual position of the plunger if desired. <IMAGE>
