Glass droplet feed - uses valve action of plunger and vessel wall to give variety of droplets in a compact assembly

摘要

In the glass droplet feed, for high glass temp. ranges and low number of cuts, the contact surface stability is achieved by the valve closing action between the plunger (1) and vessel wall (2), free of hydrostatic pressure from the column of molten glass over the valve point (1,2), but which is used for the molten glass flow for the next droplet when a formed droplet has been delivered The plunger (1) takes up a position within the vessel wall which allows molten glass to flow through by the different dias. between them, to build up the contact surface back formation (10-11), by simultaneous reclosing until the shape (11) is formed and the stabilising frequency (12) is restored. USE/ADVANTAGE - The method is for the prodn. of glass droplets of individual character. The system gives a small and compact appts. which produces a variety of glass droplets.
