METHOD OF MAKING A GLASS FORMING APPARATUS WITH REDUCED WEIGHT

摘要

A method of making a glass forming apparatus with reduced weight includes forming a cavity in the glass forming apparatus and expanding the size of the cavity by abrasively removing material from the glass forming apparatus through application of a wire saw.

1. A method for reducing the weight of a glass forming apparatus, the glass forming apparatus comprising:
a trough extending along a longitudinal length of the glass forming apparatus from a first end to a second end, said trough having a bottom surface; and a first weir and a second weir longitudinally extending along a first and second side of the trough, said first and second weirs having upper surfaces and said first and second weirs converging at a distance away from the trough to form a wedge-shaped root; wherein the distance between the upper surfaces of the first and second weirs and the bottom surface of the trough decreases between the first end and the second end; and the method comprising: forming at least one cavity between the bottom surface of the trough and the wedge-shaped root, said cavity extending along a longitudinal length of the glass forming apparatus from the first end to the second end; and expanding the size of the cavity by abrasively removing material from the glass forming apparatus through application of a wire saw.
