Abstract
Method for the manufacture of propellers for fans.The invention refers to a method designed for the manufacture of propellers for fans obtained by a combination of welding some supports to the propeller hub and riveting, welding or screwing some blades to the said supports, so that with this type of arrangement it is applicable to any type of blade independent of the size or angle. When the fan motor is the external rotor type, the outer surface is normally used as the propeller hub.
