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.

Methods of manufacturing a ribbon include contacting the ribbon with a recess of a forming roll to impart a protrusion to a first major surface of the ribbon. Methods include receiving the ribbon on a support surface positioned downstream from the forming roll. A second major surface of the ribbon is opposite the first major surface and faces the support surface. The protrusion extends in a direction away from the support surface. Methods include forming a vacuum between the second major surface of the ribbon and the support surface to bias the ribbon toward the support surface.

A method for texturing a substrate includes 3-D printing a pattern onto a substrate to form a texture. The pattern has a root mean square roughness between 40 to 1000 microns and an autocorrelation function greater than 0.5 for distances less than 50 microns.

Various aspects of methods and systems are provided, which detail: a method, comprising: depositing a hot, flexible glass-containing ribbon along a plurality of sequentially conveyed molds; rolling a pinch roller over the surface of the glass-containing ribbon, such that at least one pinch region is actuated in the glass ribbon as the glass ribbon is pinched between a pinch edge of the pinch roller and the surface of the mold; and cooling the glass ribbon, separating the glass ribbon along the pinch region into discrete glass parts.

A glass manufacturing apparatus includes a delivery apparatus defining a travel path extending in a first travel direction. The delivery apparatus conveys a stream of molten glass along the travel path. The glass manufacturing apparatus includes a first forming roll and a second forming roll spaced to define a gap that provides a glass ribbon with a width and a thickness. One or more of the first forming roll or the second forming roll include a textured feature that imparts a corresponding textured feature to the glass ribbon. The glass manufacturing apparatus includes a mold defining a mold cavity. The mold is positioned to receive a portion of the glass ribbon to impart a shape to the portion. The glass manufacturing apparatus includes a conveyor that moves the mold in a second travel direction angled relative to the first travel direction. Methods of manufacturing a glass ribbon are provided.
