Abstract: Methods and apparatus provide for: conveying a glass web from a source toward a destination in a transport direction; scoring the glass web in a width direction thereof to product a score line having a plurality of separated score segments, thereby defining a section of the glass web between the score line and leading edge of the glass web; supporting the glass web such that an increasing portion of the section of the glass web becomes cantilevered as the glass web is conveyed such that the portion of the section of the glass web is sufficiently large to generate stress in the respective score segments and drive respective cracks through the thickness of the glass web; and permitting the section of the glass web to separate from the glass web along the score line.

Abstract: Foldable apparatus can comprise a first portion comprising a first edge surface defined between a first surface area and a second surface area opposite the first surface area. Foldable apparatus can comprise a second portion comprising a second edge surface defined between a third surface area and a fourth surface area opposite the third surface area. A polymer-based portion can be positioned between the first blunted edge surface and the second blunted edge surface. In some embodiments, the polymer-based portion can comprise a polymer thickness of about 50 micrometers or less measured from the second surface area and/or the first surface area. In some embodiments, the first edge surface and/or the second edge surface can comprise a blunted edge surface. In some embodiments, a coating can be disposed over the first portion, the second portion and the polymer-based portion.
