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 produce a score line having a plurality of separated score segments, thereby defining a section of the glass web between the score line and a 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.

Le procédé comprend -une étape de traçage d'un trait de découpe (2) à la surface du verre, au moyen d'un outil de découpe (6); -une étape de rompage au moyen d'un moyen d'appui local (10) appliqué en face opposée (4B) et en regard du trait de découpe(2), le moyen d'appui local (10) étant déplacé et appuyé le long du trait de découpe (2), sur ladite face opposée (4B).
Abstract:
In one embodiment, an angle measurement device for measuring an angle between a web of material and a conveyance direction includes a mounting bracket, a shaft rotatably coupled to the mounting bracket such that the shaft is rotatable with respect to the mounting bracket, a caster portion coupled to a first end of the shaft and positioned to contact a surface of the web of material being drawn over a web conveyance pathway, where the caster portion is spaced apart from an axis of rotation of the shaft, and an angular displacement sensor coupled to the mounting bracket and positioned to detect an angular orientation of the shaft with respect to the mounting bracket, where the angular displacement sensor outputs a signal indicative of the angular orientation of the shaft with respect to the mounting bracket.
Abstract:
A method for cutting a flexible glass ribbon includes directing the flexible glass ribbon to a flexible glass cutting apparatus including a laser. The flexible glass ribbon includes a first broad surface and a second broad surface that extend between a first edge and a second edge of the flexible glass ribbon. A laser beam is directed from the laser onto a region of the flexible glass ribbon. A crack is formed through the flexible glass ribbon using the laser beam. The crack is propagated along the flexible glass ribbon using the laser beam and a local mechanical deformation in the flexible glass ribbon.
Abstract:
Glass web including a first glass-web portion (30), a second portion (40), and a splice joint (50) coupling the first glass-web portion to the second portion, wherein the slice joint includes a splice member (60) with at least one gas-permeable attachment portion. In further examples, methods of splicing a first glass-web portion to a second portion include the step of splicing the first glass-web portion to the second portion with a splice member, wherein the step of splicing includes attaching a gas-permeable attachment portion of the splice member to the first glass-web portion.
