Abstract
A method of vertically positioning ribbon engaging devices in a glass forming chamber includes suspending a contact member within the chamber a known vertical distance relative to the device, moving the contact member toward the surface of a pool of molten metal contained within the glass forming chamber while moving the device to maintain the known vertical distance; and generating a signal when the contact member engages the pool of molten metal to indicate that the device is vertically positioned said known vertical distance from the surface of the pool of molten metal.
