The film is a demonstration of the Rotadie Press made by the Deritend company of Birmingham which is a rotary cutting machine that cuts out template shapes from corrugated cardboard. A commentary describes how the machine is set up and a new die is made by welding studs onto a curved plate and adding cutting edges. We then see the machine in operation running at various speeds. It is described as 'rotadie cutting at its best'.
