US 2026/0070832 A1 · METHODS AND APPARATUS FOR MANUFACTURING A RIBBON

Abstract

A glass manufacturing apparatus includes a delivery apparatus defining an upstream portion of a ribbon travel path extending in a first travel direction. The glass manufacturing apparatus includes a forming roll extending along an axis parallel to the travel path and perpendicular to the first travel direction. The forming roll includes a recess that imparts a protrusion to a ribbon traveling along the ribbon travel path in the first travel direction. The forming roll includes a first surface defining the recess and a first surface characteristic. The forming roll includes a second surface defining an area surrounding the recess and including a second surface characteristic. The first surface characteristic is different than the second surface characteristic. During a cooling period of time, the first surface cools at a faster rate than the second surface. Methods of manufacturing a ribbon are provided.
