The cassette is moveably mountable on the dolly and includes a cassette frame having first and second cassette conveyors engagable with the dolly for moveably supporting the cassette on the dolly. A first drive wheel is attached to the cassette frame between the first and second cassette conveyors.

A location of the first axis of rotation is continuously adjustable relative to the cassette frame as the cassette moves along the path-of-travel.
