  • CHUCK WITH IMPROVED TORQUE TRANSMISSION AND CENTRALIZATION
    Publication number: 20240067479
    Abstract: An expansible chuck for holding hollow cylindrical cores used for winding and unwinding sheet material. A portion of the chuck body nearest the flange is stepped up so that the diameter of the chuck near the flange is slightly larger than the diameter of the rest of the chuck. The stepped up portion centers the chuck within the core which helps the expanding elements to uniformly grip the core.
    Type: Application
    Filed: November 6, 2023

    Applicant: Sonoco Development, Inc.
