Quick change, steady rest input and output racks, allow the tube to rotate at up to 3000 RPM for 1" tube. Strip is fed to the machine from a payoff table beneath the Bare Tube Rack or from a free standing oscillating coil payoff system. The strip is guided to the primary forming roller and spindle roller and by adjusting the angle and rolling force of the primary forming roller, the outside fibers of the fin are rolled with a uniform taper. The fin curls as a result and hugs the tube. The rolling process locates more fin material near the base of the fin and tube for advantageous fin efficiency.
