Needle perfected for machine sewing, characterized by the fact that, almost completely covering the area where there is a cavity in whose bottom has made the hole or eye for the passage of the thread, has also practiced a recess of revolution in the form of neck of elongated amphora, with arcuate generatrix of suitable radius and arrow, whose length is substantially equal to the distance that mediates from the tip of the needle proper to the lower extremity or origin of said revolution depression, giving rise to its existence the formation of a transition zone that, determining small ramps, goes progressively from the bottom of the annular depression to the outer surface of the needle.
