  • Publication number: 20110135348
    Abstract: This invention provides a steering rib for an ITB. These steering rib or ribs are applied to the ITB by placing the rib around a cylindrical fixture. The rib is held in place by a vacuum that is applied to the rib to hold it against the fixture until the rib is adhered to the inside surface of an ITB. Once the rib or ribbing is adhered to the ITB, a series of apertures directs compressed air against the rib and the ITB to release them from the fixture.

  • Publication number: 20110024024
    Abstract: Provided are apparatuses and methods of making a transfer belt. The method can include providing a hollow mandrel including an interior surface and rotating about a longitudinal axis. The method can also include dispensing a coating liquid through a dispensing tip over the interior surface of the rotating mandrel and using a doctor blade to smooth the coating liquid to form a layer of coating. The method can further include curing the layer of coating to form a seamless belt over the interior surface of the mandrel and releasing the belt from the interior surface of the mandrel, wherein the belt has a thickness uniformity in the range of about 100 nm to about 1 um.
