ABSTRACT:
Methods and apparatus for protecting the thin films during chemical and/or thermal edge strengthening treatment. In one embodiment, a portion of each individual sheet is laminated. Pairs of sheets are then sealed together such that the thin film sides face inward to form a thin film sandwich. In some embodiments, the sandwich in then immersed in a chemical strengthener. In other embodiments, a localized treatment is applied to the unstrengthened edges.
