A combined iris and shear unit for a coil forming device is provided that includes an actuator and a plurality of support members coupled together in series to support formation of a coil and connected to the actuator. Each support member further comprises a retractable shear blade. The actuator adapted to cause movement of the support members between an open position with the blades of the combined iris and shear unit being retracted away from the reform tub wall, so that coil forming takes place within the reform tub without interference. A support position with the blades extends into the reform tub and providing support for the coil; or a shear position for cutting the coil before it is extracted.
