  • the packaging manufacturer has at least two cassettes. A first cassette is in the machine during production and is adapted according to the transformation work in progress. During this time, a second cassette is being assembled and adjusted to be adapted according to the following transformation work. When changing jobs, the operator takes out the old cassette and inserts the new cassette, minimizing machine downtime.
