ABSTRACT:
A clipper apparatus is provided which is convertible between single and dual punch operation and includes a single pneumatic cylinder for driving both punches. One of the punches is driven directly by the cylinder. The second punch is connected to the first punch by means of a pin and key assembly which enables coupling or decoupling of the second punch to the first punch. Thereby the punches can be made to operate simultaneously. Alternatively, only the first punch will be driven by the pneumatic cylinder.
