GLASS MANUFACTURING APPARATUS AND METHODS

摘要

A glass manufacturing apparatus includes a forming device and an enclosure including a float bath. A plurality of rollers are arranged at least partially within the enclosure and are configured to draw a glass ribbon from the forming device, through the enclosure, and over the float bath along a draw path. The glass manufacturing apparatus further includes a thermal device configured to selectively control a local thickness of the glass ribbon at a plurality of discrete locations of the glass ribbon. A method of manufacturing a glass ribbon includes drawing a glass ribbon over a float bath within an enclosure and selectively controlling a local thickness of at least one of a plurality of discrete locations of the glass ribbon within the enclosure.
