Henry Zwilling has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Rolling machine and method thereof
    Patent number: 7406853
    Abstract: In the transverse wedge rolling machine as claimed in the invention the drive motor is a permanent magnet motor, especially a torque motor. Furthermore the rotational speed of the rollers is controlled depending on their rotary position.
    Type: Grant
    Filed: August 8, 2006
    Date of Patent: August 5, 2008
    Assignee: Langenstein and Schemann GmbH
    Inventors: Guenter Hofmann, Stelios Katsibardis, Sigfried Hausdoerfer, Henry Zwilling, Guenther Vogler, Herbert Rueger

  • Device for holding at least one roller of a rolling machine
    Patent number: 7010952
    Abstract: A device for holding at least one roller of a rolling machine that can rotate about a rotational axis includes two holding arrangements that can be arranged on opposite faces of the roller viewed in the direction of the rotational axis. The device further includes at least two coupling parts each configured for a coupled mode and an uncoupled mode. A first of the two coupling parts has at least one, preferably essentially straight first groove, and has a second groove that does not run parallel to the first groove. A second of the two coupling parts includes a first coupling element and a second coupling element, wherein the first coupling element projects further outward from the second coupling part than the second coupling element. In at least one implementation, the roller can be detached or removed from the holding arrangements when the holding arrangements are in uncoupled mode.
