Methods and apparatus for manufacturing a ribbon

A glass manufacturing apparatus includes a delivery apparatus defining an upstream portion of a ribbon travel path extending in a first travel direction. A forming roll extends 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. A substantially planar surface is positioned downstream from the forming roll and receives the ribbon. A conveyor supports the substantially planar surface. The conveyor moves the substantially planar surface in a second travel direction that is angled relative to the first travel direction. A force application apparatus biases the ribbon toward the substantially planar surface to alter a position of the protrusion relative to a major surface of the ribbon. Methods of manufacturing a ribbon are provided.
