Methods of producing glass sheets |
摘要 |
Methods of producing a glass sheet comprise the step of fusion drawing a glass ribbon along a draw direction into a viscous zone downstream from a root of a forming wedge. The method further includes the steps of drawing the glass ribbon into a setting zone downstream from the viscous zone and an elastic zone downstream from the setting zone. The method also includes the step of creating a vacuum to force the entire lateral portion of the glass ribbon to engage an anvil portion of a breaking device in the elastic zone. The method still further includes the steps of forming a score line along the lateral portion of the glass ribbon and breaking away a glass sheet from the glass ribbon along the score line while the entire lateral portion is forced against the anvil portion by the vacuum. |
