The Screw Spindle Capper Machine gets its name from the spindles it uses to tighten the caps onto the containers. Spindles are vertical rotating shafts that mostly utilizes sets of spindles or rubber wheels grip the cap and container simultaneously, applying torque to twist and tighten the cap.
Therefore, in some cases, we prefer to call the spindle capping machine by the number of rubber wheels, such as an 8-wheel capping machine. It is one of the most popular automated capping machines for screw-type caps cause it is versatile and available to fit many different threaded caps.
