Abstract
A felting needle has a working part that extends lengthwise along a part of the longitudinal extent thereof. The needle has a cross-sectional area which extends in the radial and circumferential directions of the felting needle and forms the cross-sectional area of the working part for much of the length thereof and at least one barb which penetrates into the working part which is formed by an incut running from the outer surface of the working part towards the interior of the needle. The needle includes at least one bulge which projects beyond the circumferential surface of the felting needle in the working part thereof. The bulge extends lengthwise only along a part of the working part and has volume constituents that do not belong to the barbing bead of the barb. The barb adjoins the outer surface of the bulge lengthwise along the felting needle.
