An apparatus for indicating concentricity of a rotatable glass flow control tube (14) with respect to its axis of rotation on a tube support frame (20) in a glassware forming system includes a base (34, 36) for securement on the tube support frame and a slide (66) mounted on the base for radial movement toward and away from an outside surface of the glass flow control tube. A roller (68) is positioned on the slide for rolling engagement with the outside surface of the flow control tube as it rotates on the frame, and an indicator (74, 76) is coupled to the slide for indicating radial movement of the slide, indicative of radial movement of the tube outside surface with respect to its axis of rotation, as the tube is rotated on the tube support frame. <IMAGE> |
