Abstract
Helical ferrule for the folding of umbrella characterized by the fact that it consists of a strip with one flat face and the other convex -section in a half-round or similar- wound in a cylindrical helix, leaving the inside flat faces and the convex ones outside of the strip, with the essential characteristic that the internal diameter of the ferrule must match a certain adjustment with the upper part of the folded umbrella to which it is intended, so that it embraces the folded fabrics thereof.
