Abstract: Film changing equipment for rapidly changing films contained in flexible sheaths in radiological X-ray equipment, in which the sheaths containing the films are conveyed by endless conveyor belts which are transparent to X-rays from a magazine into the correct position for the X-ray exposure and then transferred into a delivery box under the control of switch means. The switch means cause the conveyor belts either to pick up the next available sheath in the magazine or to leave it in the magazine. At least one pair of cooperating endless belts convey the next available sheath presented to them by feed means in the magazine into exposure position by tightly enclosing and gripping each sheath between adjacent faces of codirectionally and synchronously travelling portions of said endless belts.
