Abstract
A roll (10) of glass ribbon (20), having a thickness of 0.3 mm or less, wherein a thickness compliant material interlayer (40) is wound together with the glass ribbon. The characteristics of the interlayer are chosen to form the roll with minimal lateral offset (9). For example, the static coefficient of friction between the interlayer and the glass ribbon may be greater than or equal to 3.0 (as measured with a vertical force of 0.5 N). Other characteristics may include the width, thickness, and compliance, of the interlayer. There is also disclosed a method of rolling a glass ribbon wherein the roll winding parameters, for example web tension and pressure between the layers of the roll, are chosen to minimize the lateral offset.
Claims20
A roll of glass ribbon, comprising:
- a glass ribbon;
- an interlayer wound together with the glass ribbon, wherein the glass ribbon has a thickness of 0.3 mm or less,
- wherein the static coefficient of friction between the interlayer and the glass ribbon is greater than or equal to 3.0 (as measured with a vertical force of 0.5 N).
A method of winding a glass ribbon, comprising:
- winding an interlayer together with a glass ribbon, wherein the glass ribbon has a thickness of 0.3 mm or less,
- wherein the static coefficient of friction between the interlayer and the glass ribbon is greater than or equal to 3.0 (as measured with a vertical force of 0.5 N).
A roll of material comprising:
- interleaving material wound together with glass ribbon, wherein a pressure between layers in the roll is ≦10 pounds per square inch (0.703 kg/square cm), and is greater than 0 pounds per square inch (0 kg/square cm).
