Abstract: An apparatus for drawing a glass ribbon including a shroud surrounding the glass ribbon and an edge roll that penetrates the shroud to contact the glass ribbon. The apparatus includes regulating a pressure within the seal assembly to be equal to or less than a pressure within the shroud and prevent ingress of relatively cooler outside gas into the hot interior of the shroud. The edge roll utilizes an air bearing to minimize friction that can produce periodic fluctuation of the ribbon as the edge roll is displaces in response to variations in the ribbon thickness or equipment dimensions.

Abstract: Apparatus for making dual component fibers is provided and includes a spinner having a peripheral wall. The spinner includes orifices located on the peripheral wall thereof for centrifuging the dual component fibers, with the spinner being divided into a series of compartments by baffles positioned circumferentially around the interior of the peripheral wall. The baffles are positioned at an angle of from about 5.degree. to about 75.degree. from vertical, and most preferably about 45.degree. from vertical. The number of orifices on the spinner peripheral wall can thus be increased to increase the throughput of fibers from the spinner while still maintaining a minimum required spacing between orifices for the structural integrity of the spinner.
