A method is provided for scoring glasses. The method includes the steps of generating a deep crack in the glass along an intended separation line by exerting pressure onto the glass surface using a rigid scoring tool, wherein the scoring tool, by being pressed against the glass surface and due to the advancement force while introducing the deep crack generates a zone of elastic strain in the glass in a direction along the glass surface and perpendicular to the separation line, which extends in an arc in the plane defined by the separation line perpendicular to the glass surface such that one leg of the arc is located close to the contact point of the scoring tool on the glass surface and another leg is located inside the glass. The arc being open towards the advancement/advancement direction of the scoring tool.

Methods for manufacturing a glass ribbon include moving the glass ribbon along a travel path in a travel direction. Methods include directing a first ribbon portion of the glass ribbon to a winding apparatus to wind the first ribbon portion into a roll. Methods include detaching the first ribbon portion from a second ribbon portion of the glass ribbon. Methods include separating the second ribbon portion into a plurality of separated ribbon portions. Methods include directing a first set of the plurality of separated ribbon portions toward a disposal apparatus to crush the first set of the plurality of separated ribbon portions. Methods include forming a stack with a second set of the plurality of separated ribbon portions. A glass manufacturing apparatus is provided.

A method and apparatus for processing glass comprising a forming apparatus in a first processing zone, the forming apparatus configured to form a glass ribbon having a first direction of travel in the first processing zone. The apparatus also includes a first cutting apparatus in a second processing zone, the first cutting apparatus configured to separate one or more portions of the glass ribbon, the glass ribbon having a second direction of travel. The apparatus includes a first buffer zone between the first processing zone and the second processing zone in which the glass ribbon is supported in a first catenary between two, spaced-apart payoff positions. The second direction of travel in the second processing zone can be orthogonal to the first direction of travel in the first processing zone.
