Embodiment Construction

[0025] Embodiments described herein generally involve changing the MD and / or CD curvature (e.g., flipping from convex to concave curvature) of a continuous flexible glass ribbon at various locations throughout the process from root to winder or winder. Curvature) minimization, and the apparatus and method for the continuous manufacturing of flexible glass ribbon. A number of processing zones and buffer zones can be provided in the process wherein the shape of the continuous flexible glass ribbon can be controlled by positioning the zones relative to each other to minimize MD and / or CD curvature variations of the flexible glass ribbon. In some embodiments, the method can include maintaining the flexible glass ribbon with a concave or substantially linear MD and / or CD curvature through at least two or more adjacent regions in the process.

[0026] While glass is generally known to be a brittle material, inflexible, and prone to scratches, chips, and breaks, glass with a th...

Abstract

Disclosed herein are methods for continuous processing of a thin, flexible glass ribbon through various processing zones and maintaining a concave or substantially linear machine directional (MD) and/or cross-directional (CD) curvature of the flexible glass ribbon through at least two or more contiguous zones in the process. Apparatuses for the continuous processing of a thin, flexible glass ribbon while maintaining a desired MD and/or CD curvature are also disclosed herein.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 275981, filed January 7, 2016, upon which this application is based and incorporated by reference in its entirety This article. technical field [0003] The present disclosure relates to apparatus and methods for continuously processing a flexible glass ribbon, and in particular, to the process of maintaining a concave or substantially flat curvature in the machine direction of a flexible glass ribbon through at least a portion of the process. A method for continuous processing. Background technique [0004] Glass processing equipment is commonly used to form various glass products, such as glass sheets for electronic devices (eg, LCDs, etc.). Glass substrates in flexible electronics applications are becoming thinner and lighter. Glass substrates having a thickness of less than 0.5 mm, such as less than...
