  • Centrifugal clamp on a high speed print drum
    Patent number: 4250810
    Abstract: A clamp for holding a flexible sheet on a rotary carrier tightens the grip on, and pulls, the sheet upon rotation of the carrier, as a result of centrifugal forces generated on two weights attached to two cooperating arms within the clamp. The magnitude of the grip-tightening force is dependent upon the mass of a grip-tightening weight attached to the clamp. The magnitude of the sheet-pulling force is dependent upon the mass of a sheet-pulling weight attached to the clamp. The clamp faces are mounted for concurrent movement along the periphery of the carrier to prevent tearing or other damage to the sheet when it is pulled as the carrier is rotated.
