METHODS AND APPARATUSES FOR STEERING FLEXIBLE GLASS WEBS

摘要

Methods and apparatuses for steering flexible glass webs are disclosed. In one embodiment, a steering device for non-contact steering of a glass web having a conveyance direction and a cross direction normal to the conveyance direction includes a fluid injection bar having an elongate axis oriented in a cross direction of the glass web. The steering device also includes a pivot bearing assembly coupled to the fluid injection bar such that the fluid injection bar is pivotable in a plane perpendicular to the conveyance direction of the glass web, an actuator coupled to the fluid injection bar for adjusting the orientation of the fluid injection bar with respect to the glass web, and an edge detection device positioned proximate to an edge of the glass web for evaluating a position of an edge of the glass web.
