Abstract
An overload protection device for the clamping portion of a tube cutoff die set. The overload protection device is used to prevent destructive overload forces in the event a mechanical obstruction prevents the tube clamping die jaws from fully closing in response to the forces applied by a control cam. The overload protector comprises a wedge mounted between rollers. If overload occurs the wedge is squeezed out of position against the operation of a compression spring. After the overload condition is eliminated the wedge is returned to position by the compression spring.
