Needle perfected for machine sewing, characterized by the fact that on the face presenting the cavity, at the bottom of which the hole or eye for passing the thread has been practiced and partially associated therewith, there is a notch of generatrix preferably cylindrical and of convenient radius of curvature, which gives rise to the existence of a transition plane that, forming a small ramp, progressively links the bottom of the antecedent cavity with the outer surface of the needle.
