APPARATUSES FOR STEERING FLEXIBLE GLASS WEBS AND METHODS FOR USING THE SAME In one embodiment a method of steering a glass web (102) includes directing the glass web (102) in a conveyance direction on a web conveyance pathway, contacting at least one surface (104) of the glass web with at least one wheel (117) of at least one idler roller (108), the at least one wheel (117) of the at least one idler roller (108) having an axis of rotation parallel to a surface of the glass web (102), detecting an angle (135) between a centerline (107) of the glass web (102) and the conveyance direction with an angle measurement device (110), and modifying an orientation of the at least one idler roller (108) and the at least one wheel (117) about an axis of rotation substantially orthogonal to the web conveyance pathway to shift the glass web (107) based on a detected angle (135) between the centerline(107) of the glass web (102) and the conveyance direction (x) of the web conveyance pathway.
