Apparatuses for steering flexible glass webs and methods for using the same

A method of steering a glass web comprising:

• directing the glass web in a conveyance direction on a web conveyance pathway;
• contacting at least one surface of the glass web with at least one wheel of at least one idler roller, the at least one wheel of the at least one idler roller having an axis of rotation parallel to a surface of the glass web;
• detecting an angle between a centerline of the glass web and the conveyance direction with an angle measurement device;
• and
• modifying an orientation of the at least one idler roller and the at least one wheel about an axis of rotation substantially orthogonal to the web conveyance pathway to shift the glass web based on a detected angle between the centerline of the glass web and the conveyance direction of the web conveyance pathway.

A method for producing a glass web comprising:

• melting glass batch materials to form molten glass;
• forming the molten glass into the glass web with a fusion draw machine comprising an inlet, a forming vessel, and a pull roll assembly;
• drawing the glass web through the pull roll assembly;
• directing the glass web in a conveyance direction on a web conveyance pathway;
• contacting at least one surface of the glass web with at least one wheel of an idler roller, the at least one wheel of the idler roller having an axis of rotation parallel to a surface of the glass web;
• detecting an angle between a centerline of the glass web and the conveyance direction with an angle measurement device;
• and
• modifying an orientation of the idler roller and the at least one wheel about an axis of rotation substantially orthogonal to the web conveyance pathway to shift the glass web based on a detected angle between the centerline of the glass web and the conveyance direction of the web conveyance pathway.
