Abstract
Official abstract text for this publication.
A roll ( 10 ) of glass ribbon ( 20 ) and an interleaf material ( 40 ) disposed in alternating layers, wherein a layer of the interleaf material is pinned to an adjacent layer of the glass ribbon by an electrostatic force that is of a value so that a shear force required to cause slip between the interleaf material and the glass ribbon is greater than or equal to 10 times that required to cause slip between them when not electrostatically pinned together. Methods for winding and unwinding the roll, as well as an apparatus for winding the glass ribbon and interleaf material into a roll, are also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A roll of glass comprising: a glass ribbon and an interleaf material rolled together so as to be disposed in alternating layers, wherein a layer of the interleaf material is pinned to an adjacent layer of the glass ribbon by an electrostatic force, wherein the electrostatic force is of a value so that a shear force required to cause slip between the interleaf material and the glass ribbon is greater than or equal to 10 times that required to cause slip between the interleaf material and the glass ribbon when not electrostatically pinned together. 2. The roll of glass according to claim 1 , wherein the electrostatic force is of a value so that when the interleaf material is pinned to the glass ribbon over a contact area of 176 square inches (1135 square cm) by the electrostatic force, a shear force required to cause slip between the interleaf material and the glass ribbon is greater than 100 ounces (2835 grams). 3. The roll of glass according to claim 1 , wherein the glass ribbon has a thickness of ≦0.3 mm.
