Abstract:
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.
