Title: Tire inspection machine presenting an X-ray image of the entire width of the tire

Abstract: An X-ray machine for production line inspection of tires places each tire in turn with one sector of the tire inside of a U-shaped arrangement of three fluorescent screens so that one screen faces the tread and the other two face the sides of the tire. An X-ray source inside the bead circle of the tire produces X-ray shadow pictures on the screens, which are separately viewed by a video camera, with an image of the picture on each screen transferred to a third of the target of a storage tube, so that a composite image of the entire width of the tire sector can be displayed on a picture tube. The tire is rotated stepwise for display of still pictures of every sector of the tire.
