Abstract
An apparatus comprises a mandrel having a longitudinal axis and further comprises a plurality of pivoting elements spaced apart along a circumference of a cross-section of the mandrel. Each of the pivoting elements is pivotable around a transversal axis that is perpendicular to the longitudinal axis.
Claims19
An apparatus comprising:
- a mandrel having a longitudinal axis;
- and
- a plurality of pivoting elements spaced apart along a circumference of a cross-section of the mandrel, each of the plurality of pivoting elements pivotable around a transversal axis that is perpendicular to the longitudinal axis,
- wherein each of the plurality of pivoting elements comprises:
- a first arm that is pivotable toward or away from the mandrel around the transversal axis;
- and a second arm intersecting the first arm at an angle of less than 180 degrees so that the second arm is pivotable toward or away from the mandrel as the first arm pivots away from or toward the mandrel.
