  • Patent number: 7780805
    Abstract: Belt material is wrapped around a small diameter mandrel. Instead of cutting the belt to length, the material is then continued to be wrapped around the mandrel, forming a belt material overlap, and held under tension. An ultrasonic welding horn is then traversed across the width of the belt overlap. As this horn is traversed across the overlapped joint, the horn not only joins the belt material wrapped around the mandrel but, as the trailing edge is held under tension, the horn also separates or severs the trailing edge of the material from the welded seam.

  • Publication number: 20090294513
    Abstract: An ultrasonic welding member for use in welding seamed flexible belts to produce smoother seams having reduced seam thickness. The ultrasonic welding member has a unique configuration, that includes an increased tip surface formed in such a manner that more energy from the horn is dispersed over the seam overlap region for a longer duration of time to produce a smoother and thinner weld.

  • Patent number: 7507510
    Abstract: An imaging member containing an optional supporting substrate, a photogenerating layer, and at least one charge transport layer of at least one charge transport component, at least one polyphenyl ether of the formula wherein each R1, R2, and R3 is independently selected from the group consisting of hydrogen, alkyl, aryl, alkoxy, substituted alkyl, substituted aryl, substituted alkoxy, and halogen, and n is from about 1 to about 10, and a thiophosphate.

  • Patent number: 7491281
    Abstract: A method is disclosed that involves providing a sheet of thermoplastic belt material having a first end with a first radius of curvature, providing a mandrel having a second radius of curvature that is no more than 12% larger or smaller than the first radius of curvature, wrapping the sheet of thermoplastic belt material on the mandrel to form a material overlap region, and welding the material overlap region to form a seamed belt. In one embodiment, instead of cutting the belt to length, the material is then continued to be wrapped around the mandrel, forming a belt material overlap, and held under tension. As the ultrasonic welding horn is traversed across the width of the belt overlap, the horn not only joins the belt material wrapped around the mandrel but, as the trailing edge is held under tension, the horn also separates or severs the trailing edge of the material from the welded seam. A seamed belt is also disclosed.
