Abstract:
A roller includes an outer cylindrical portion and an inner cylindrical portion arranged concentrically with the outer cylindrical portion. A plurality of connection spokes are provided for connecting the outer cylindrical portion and the inner cylindrical portion to each other, wherein each of the connection spokes are connected along a non-linear connection path with respect to an axis extending between the outer cylindrical portion and the inner cylindrical portion of the roller to provide a tunable spring constant in the roller.
