Abstract

An edge-protected product and a finishing method for the product. The product comprises a first web and a second web intermittently joined to the perimeter region of the major surface of the panel to be protected. The joined webs provide the desired level of protection for the perimeter areas and edge surfaces of the panels. Intermittent bonding allows clean and easy separation of sheets and webs that cannot provide continuously bonded webs. Products where laser cutting is used for separation protection, edge protection products with intermittently joined areas allow separation without laser irradiation to the web, and therefore do not produce toxic fumes of oxidation or carbonization, melting of the web caused by laser heat and / or break down. The present invention is especially useful for protecting thin glass sheets, especially those in roll form.

Description

[0001] This application claims priority benefit under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 13 / 117,564, filed May 27, 2011, the contents upon which this application is relied upon are incorporated herein by reference. technical field [0002] The invention relates to an edge protected product comprising a board and an edge protected web, and a finishing method for the product. In particular, the present invention relates to a thin glass sheet product comprising a glass sheet and an edge protection web bonded to the perimeter area of ​​a major surface in a batch mode, and to finishing for said product method. The invention is useful, for example, in the manufacture and finishing of ultra-thin glass sheet products for use in display devices. Background technique [0003] Plates such as glass plates, glass-ceramic plates, ceramic plates and crystal wafers and the like are widely used in many processes and devices. Each panel generally includes at least two...
